Beijing Kanggaote instrument and equipment guideThe circuit breaker is an important equipment in the substation, is the main control and protection element in the power grid, it plays an important role in connecting and disconnecting the circuit, cutting off and isolating the fault part.
TM1800 Dual Earth Circuit Breaker Analysis System
The circuit breaker passes the load current under the normal operation of the system, and is used to interrupt the fault current when the system is grounded or short-circuit fault, so as to ensure that the equipment in the station is not affected by the fault current to the greatest extent, avoid the further expansion of the accident, and reduce the load loss. Therefore, the mechanical characteristics test of circuit breaker is very important for the safe and stable operation of the power grid.
TM1800 Circuit Breaker Mechanical Characteristics TesterIt is a state-of-the-art equipment designed to test the mechanical characteristics of circuit breakers. It is a key tool in maintaining the stable operation of the power system and providing safety assurance, with rich functions, high precision and easy operation.
The instrument can evaluate the operating state of the circuit by measuring the time, speed, stroke, dynamic and static resistance, coil current and other parameters of the switchgear. The instrument's unique dynamic capacitance (DCM) double-ended grounding test method, in the narrow space test of GIS, only need to install the current clamp and ferrite kit in the grounding circuit to carry out the time test in the case of double-ended grounding, through the current change curve in the circuit can accurately distinguish the opening time, to ensure that the test data is more accurate, which is also Megger's unique patented technology.
China's GB 1984-2003 "High Voltage AC Circuit Breaker" standard 6101.1.3. The characteristics and setting values of the circuit breaker that should be recorded before and after the test require that the characteristic values and setting values such as opening time, closing time, main circuit resistance, time-stroke characteristic curve need to be recorded and calculated. TM1800 circuit breaker mechanical characteristics tester meets the requirements of the above standards for testing, and can provide accurate judgment basis for the state of circuit breaker.
The instrument can be used in many fields such as power grids, subways, railways, airports, nuclear power, etc., and has been put into use in Guangdong, Sichuan, Zhejiang, Shaanxi, Inner Mongolia and other places across the country, helping users solve many test problems and making testing easier!
