Abstract

The invention discloses a opening and closing coil test system, and the system comprises a test cabinet which comprises an industrial control computer and a measurement and control subsystem which are connected with each other; a temperature and humidity test box which is used for testing the service life of the opening and closing coil together with a service life test tool, is connected with the industrial personal computer through a communication cable and a test cable, and is controlled by a measurement and control subsystem in the test cabinet; and a coil structure test tool which is connected with the test cabinet through a communication cable and is used for carrying out structure test on the opening and closing coil, specifically comprises a turn-to-turn insulation tester and a coil turn number tester. The opening and closing coil can be tested quickly and conveniently.

Description

technical field [0001] The invention belongs to the technical field of circuit breaker opening and closing coil testing, and in particular relates to an opening and closing coil testing system. Background technique [0002] A circuit breaker is a switching device that can close, carry and break current under normal circuit conditions and close, carry and break current under abnormal circuit conditions within a specified time. It can be used to distribute electrical energy and can Protect the circuit, etc. When the circuit is seriously overloaded, short-circuited and under-voltage, the circuit breaker can automatically cut off the circuit to protect the circuit. [0003] The closing coil is the core component of the electric closing part in the high-voltage circuit breaker. It is a hollow cylindrical coil wound with copper wire. The development and type testing of the short-circuit current of the opening and closing coils must be carried out. [0004] The traditional test m...
