      Views:

       I. Overview
      With the development of society, people have higher and higher requirements for the safety and reliability of power consumption. High-voltage circuit breakers have the dual tasks of control and protection in the power system. The performance of the power circuit is directly related to the safe operation of the power system. The mechanical characteristic parameter is one of the important parameters for judging the performance of the circuit breaker.
      The YCKG-A Switch characteristic tester is a special instrument developed by the company to meet the needs of various high-voltage switch action characteristics tests, and can accurately measure various oil grades such as less oil, more oil, vacuum, sulfur hexafluoride, etc. Mechanical dynamic characteristics of high voltage circuit breakers. For circuit breakers with closing resistors, the closing resistor and switching waveform can be accurately measured. The instrument adopts large-screen display, Chinese characters prompt man-machine dialogue operation, Chinese characters display results and printout, with intelligent, multi-function, accurate data, strong anti-interference, simple operation, small size, light weight, beautiful appearance, etc...

      2.Instrument characteristics
      It is applicable to SF6 switch, GIS combined electrical appliance, vacuum switch and oil switch of all models of metal contact produced at home and abroad.
      Linear travel sensor and rotary sensor are easy to install.
      Mainframe large screen, transparent, background light LCD, contrast electronic adjustment. Chinese menu prompt operation, switch action once, display all data and waveform map.
      The host can store multiple groups of on-site opening and closing test results, and the real-time clock in the host is convenient for archiving and storing the test date and time.
      Built in fast micro printer to print all data and atlas.
      The instrument has powerful data analysis function, which can effectively analyze various index parameters of the mechanical characteristics of the circuit breaker.

      3.Performance introduction

      Time: inherent opening and closing time of 12 common fractures. In phase synchronization, in phase synchronization.
      Reclosing: closing opening, opening closing, opening closing opening process time of each fracture: one opening time, one closing time, two opening time, golden short time, no current time value.
      Bounce: closing bounce time, bounce times, bounce process and bounce waveform of each fracture; opening bounce amplitude of each fracture.
      Speed: rigid opening and closing speed, maximum speed, time travel characteristic curve.
      Current: opening and closing current value and current waveform of opening and closing coils.
      Action voltage: dc30-250v / 20A digital adjustable circuit breaker action power supply is provided in the unit, which automatically completes the low voltage action test of the circuit breaker and measures the action voltage value of the circuit breaker.
