  • Product Introduction

      ZCWS-100 Gas relay test bench is a new design of gas relay check and test equipment. The action mechanism of the gas relay calibration stand simulation of transformer internal fault, a new generation of embedded control and high precision sensor technology, accurate detection of the action of gas relay velocity value and action of gas volume, fast test speed, high accuracy, good repeatability test. Using hand wheel and screw driving mechanism, the operation of gas relay is easy and reliable, and the performance is reliable.
      ZCWS-100 The gas relay test bench is suitable for the verification of various types of gas relay in China and abroad. It can realize the sealing performance test of gas relay, the detection and verification of heavy gas protection action velocity and light gas protection action gas volume value. Each test project is completed independently and does not affect each other. The software interface is exquisite and the operation is simple. The test results can be easily saved, read and network transmission.

  • Product Features
     1.The ambient temperature -10ºC~+40ºC, the humidity ≤85%, no dramatic changes in ambient temperature places;
     2.No strong magneto electric interference, corrosion, inflammable and explosive gas or liquid place
     3.No special installation is required, only a flat and solid foundation (such as the ground) is needed.
     4.The calibration table should have enough work space on the side of the front, back and liquid level observation holes to facilitate the operation, dismantling, maintenance and cleaning of the equipment.
     5.The calibration stage is powered by three phase four wire system. When wiring is selected, wiring is required according to the electrician's manual, ensuring safety. If the wiring distance exceeds 25M, it is recommended to increase one specification wiring.
     6.The checkout console must be reliably grounded before use. The grounding wire must not be connected to other large current loads, but must be separately grounded. The earthing wiring must be shorter and the better.
      7.A proper amount of qualified transformer oil must be added before the first use of the instrument, and the filling hole is located at the oil return tank. It is suitable for the liquid level meter to observe the hole oil level in the distance of 6~8 centimeters from the upper cover of the tank.
