The Protective Oil Surge Relay (OSR) operates on the principle of Oil turbulence. Copyright © 2022 Zhou, Xie, Chen, Guan, Deng, Liu and Yan. 1088/1755-1315/495/1/012008. Oil Surge Relay (OSR) is also fixed with a glass window to easily check changes in oil colors. Predominate and rotate the whole system until it reaches the top stop, with the Mercury switch in the open position. Study on Oil Flow Surging and Protection Optimization for on Load Tap Changer of Converter Transformer. The action pressure range and action percentage are shown in Table 5. In order to reduce the breaking capacity of the main contact, the value of transition resistance should be lower. The made heat causes decomposition of electrical device oil and gas bubbles are made. Minimum frictional resistance to fluid flow.
Please add weight and delivery pincode to get estimate shipping price. Transformers, its types and installation 4. You seem to be 'Offline'. If high eddy currents, local overheating, or partial discharges occur within the tank, bubbles of resultant gas rise to the top of the tank. More... Oil surge relay rs 2001 type: rs 2001 connection: with flanges with 4 holes switching system: no alarm: normaly â open disconnection: normaly â open oil flow tripping the flap valve 1, 20 ms. Oil surge relay in transformer les. more... Buchholz relay detects the fall in oil level due to formation of gases after any internal fault inside the transformer. 97 kg/(ms), the thermal conductivity is 0. Buchholz relay is used for protection of oil filled transformers/reactors fitted with conservators against low oil level and internal faults.
Minimum order quantity - 5 Unit/Units. This relay is a security device used in the fields like the transmission of power, as well as distribution. The curve drawn according to the above simulation data is shown in Figure 11. Fusion Energ 37, 346–353. The following work of this paper will analyze more types of OLTC and summarize a unified protection configuration method. Difference between Buchholz Relay and Oil Surge Realy: Generally there is confusion between operation of Buchholz relay and Oil surge relay. Years Of Experience. The corresponding breaking capacity P1 of the main contact, the switching capacity P2 of the transition contact and the total breaking capacity P3 can be expressed as: The relationship between the switching capacity P1 of the main contact and P2 of the auxiliary contact, total switching capacity P3, and coefficient n of transition resistance is shown in Figure 3. Oil surge relay in transformer formula. Whenever the amount of oil in the transformer drops. The oil flow surging is related to the energy generated during the tap changing process, the volume of the oil chamber, the height difference between the oil chamber and the conservator, and the diameter of the pipe. The Buchholz relay purpose is to give the protection to a transformer from the different faults happening in the transformer like the Short circuit, inter-turn, core, incipient, etc. Therefore, the calculation area is set to be filled with transformer oil (#25), with oil pressure of 100 kP A and oil temperature of 40°C. Figure 10B shows the velocity field and pressure field at the central section of the oil barrel of the OLTC before the arc energy of the main contact is added, after the moving contact and fast mechanism act for 13. Thus, it is the aim to make sure an exact measurement of the transformer condition.
Buchholz Relay Construction The Buchholz Relay consists of two elements, namely the upper element, and the lower element. Characterizing the Diverter Switch of a Load Tap Changer in a Transformer Using Wavelet and Modal Analysis. Otherwise, a similar test method is recommended. Liquid-flow control relays for OLTC | Hitachi Energy. Buchholz Relay The main features of Buchholz relay include field proven consistency, No fake alarms, the design is robust, special design for OLTC applications, airtight transformers and transformers with conservator with a rubber bag, etc.
Hence, protecting the Transformers and its accessories from failure is of utmost importance in the smooth functioning of the Power system. A magnetically held paddle attached to the bottom float is positioned in the oil-flow stream between the conservator and transformer tank. Working Principle of OSR Relay: Under normal condition, the OLTC OSR relay reads normal pressure, since the relay become in active. 2 times the rated load, the oil flow speed reaches 1. Western Express Highway, Nr. Oil surge relay in transformer book. Get Best QuoteRequest A Callback. The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. If the oil flow relay of the converter transformer OLTC is one of the above three oil flow relays, the pressure threshold of the matched oil pressure relay can be set with reference to the above results. Transformer 10, 48–52. The tap selector connects the tap in advance according to the tap sequence and makes it bear continuous load. Xu, H., Wang, J., Liao, W., Shan, H., and Wang, J. Mercury switches employed are of a special design to prevent maloperation due to excessive transformer vibration. Each solid wall is set as an adiabatic nonslip boundary, without the consideration of the influence of wall roughness.
It can be seen from Table 1 that 1) the recovery voltage of the auxiliary contact is greater than that of the main contact; 2) the breaking current and the recovery voltage of the main contact is independent of the transition resistance R and the stage voltage, respectively, while those of the auxiliary contact are related to the transition resistance R and stage voltage. The Mercury switches were connected to sensitive detecting equipment and no maloperations were recorded. In the process of switching, when the moving and static contacts are separated from contact, the main contact and transition contact not only rotate with their own rapid mechanism but also rotate around their own rotating shaft under the action of the spring at the bottom of the contact. The following are the drawbacks of the Buchholz relay. From the above Buchholz relay manual, finally, we can conclude that these relays are not responsive to external servicing required throughout the function. Buchholz Relay Role in Oil Filled Transformers. During tap changing, the insulating oil in the chamber will be heated, expanded, and surged by the energy generated from arc breaking.
It can be seen that by increasing the applied pressure value continuously, the correct rate of oil flow relay action is gradually improved, and finally 100% correct action is achieved. Some scholars have explored the cooperation between OLTC oil flow surge and nonelectric protection by means of the equivalent test. If a small amount of gas is found in this relay when the transformer is new (a few months after startup), it is probably just air that has been trapped in the transformer structure and is now escaping; there is little cause for concern. So, How to reduce earth leakage current in case that isolation transformer is used? Developed & Managed by SME Business Services Ltd. These contacts are typically connected to cause the transformer to trip. In terms of OLTC operation characteristics analysis, electromagnetic transient simulation research has been carried out for the switching process of the OLTC, and quantitative analysis has been obtained from the two aspects of amplitude and phase.
Since the gasification of transformer oil caused by arcing is not considered in the simulation, the actual oil flow velocity should be higher than that of the numerical simulation, so it is necessary to consider increasing the setting value of oil flow relay. Based on which, the optimization suggestions on the protection relay threshold configuration of OLTC oil velocity and oil pressure are put forward. Through the correlation analysis of the transition resistance coefficient, the arcing energy, oil flow, and oil pressure data are shown in Table 2, and it can be found that the correlation coefficients of transition resistance coefficient–arcing energy, transition resistance coefficient–oil flow, and transition resistance coefficient–oil pressure are −0. The switches of the contacts stopped and an alarm circuit strengthened. Pbwel Mercury Switch Type Buchholz Relays consists of a lightweight container fitted with two pivoted elements. Product Price: Rs 8, 500 / UnitGet Best Price. The paddle activates the same magnetic switch as the bottom float mentioned above, which trips the transformer. 2015) improved the on-load tap changer of the double transition resistance branch triggered by micro-arc and established a new model of active trigger combined with the double transition resistance branch. These are known for their light weight, accurate measurements, excellent quality and sturdy design. According to the test report, the arcing time does not exceed 12 ms, with an average of 6 ms. The process from contact to separation is the opposite.
Failure of Transformers or its accessories will lead to power outages and repairing of the same will be time consuming and expensive process. When the relay is full of oil, both cylinders appear to lose weight. 5 m/s are used for the comparative experiment.
