LS2162
Lshun
The LS2162 Transformer Comprehensive Tester integrates a DC resistance tester and transformer ratio tester into one device for testing large power transformers.
Product Design
1.One-time wiring completes all test items, reducing the workload of on-site testers.
2.Equipped with a 7-inch color touch LCD screen for control and display, providing a user-friendly interface.
3.Built-in micro printer for on-site printing of test results.
4.USB storage function for external storage of test results.
5.One isolated Rs232 communication interface with standard protocol communication.
6.Bluetooth communication module with standard protocol wireless communication.
7.High-reliability RS485 bus for internal communication.
8.lsolated circuit design to eliminate interference between test functions; hardware and software filtering to improve anti-interference capability; good
grounding and shielding measures to enhance overall anti-interference capability.
DC Resistance Test
1. Three-phase simultaneous testing and automatic magnetization.
2. High and low voltage current and potential test leads can be connected to the transformer at once, eliminating the need to switch test leads during the
test.
3. For star-connected windings with a neutral point, the A0, B0, and C0 phase resistances can be tested simultaneously, significantly saving test time.
4. For an internally delta-connected three-phase five-limb transformer, the automatic excitation method can be used during low-voltage side testing,
which offers fast testing speed.
5. Displays and prints all test data of high, medium, and low voltage windings, automatically calculates three-phase unbalance, and prints resistance values
converted to rated temperature.
6. Comprehensive back EMF protection.
Transformer Ratio Test
1.Chinese/English menu prompts, simple and convenient operation.
2.Three-phase testing only requires inputting the high-voltage side connection method to automatically measure the group.
3.Capable of both single-phase measurement and automatic testing of three-phase windings. The connection group can be arbitrarily selected,
completing the measurement of parameters such as the ratio, error, and connection group of AB, BC, and CA phases in one go.
4.Protection function for high and low voltage reverse connection.
5.Fast testing speed, completing single-phase testing in 15 seconds.
6.Protection functions for transformer short-circuit and inter-turn short-circuit.
VRP Series Varnish Removal Oil Purifier
Application
Used in gas and steam turbine, compressor, to remove dissolved and suspended soft pollutants in oil products, sludge and other harmful substances. Avoid turbine failures and expensive oil changes due to paint film problems. When the film is formed, the loss of production is very high. The initial formation of the film is known as a soft pollutant, caused by hot spots in the system, such as bearings, pumps, and high flow on-line filtration. Recent studies have found that the existence of soft pollutants can be divided into dissolved state and suspended state, by removing these soft oxides can avoid the production of paint film. Once the film forms, it will clog valves, filters and other small links, and the life of the oil will be significantly reduced.
The formation of cleaning film will cause the following adverse consequences: valve adhesion, loss of control, resulting in unit failure or startup failure; Filter plugging, limiting oil flow, resulting in oil temperature rise and wear increase; Heat exchange failure, oil temperature rise; Sandpaper surface, increase component wear; Forming paint on the bearing, limiting flow, increasing wear and temperature; Frequent oil changes and system flushes. When the soft pollutants are dissolved in the oil, typically when the oil temperature is above 40℃, they cannot be removed by ordinary mechanical filtration or electrostatic filtration, and these soft pollutants show natural magnetism. For polar absorption, the cooler metal surface "cold spot", i.e. the valve and cooler. When the temperature of the oil is lowered, the thermal stability of the soft pollutants is less than that of the oil, so they are more likely to bake hard on hot surfaces, such as axial shafts.
VRP paint film cleaner. It achieves revolutionary and efficient removal of soft pollutants (dissolved and suspended) from oil products, including gas and steam turbines and compressors under high temperature operation. The warm oil is pumped from the lowest point at the bottom of the tank to the VRP paint film purifier by the equipment's own transfer pump. After cooling treatment (using the thermal stability of the paint film is worse than that of oil), the paint film, particulate matter and moisture are removed by the filter element with wood fiber as the raw material (no need to use ion-exchange resin filter material, greatly saving the cost of use).
Features:
● Increase system reliability and stability. ● No more shutdowns and startup failures caused by paint film.
● No longer need to clean the tank and system flushing. ● Increase jacking oil pressure, more stable bearing temperature.
● Improve the life of oil products, blood additives and system components, such as bearings, valves, seals, etc.
● Great savings can be achieved by avoiding turbine failure and extending the life of oil products. Features:
