Problems solved by technology

This method is relatively primitive, takes up manpower, has certain risks, and it is difficult to meet the requirements of the relevant standards for the operating speed of the handle, and has certain randomness, which is not conducive to objective and fair product testing.
[0004] Some foreign test stations use automatic devices to reduce the influence of human factors on the test results. Electromagnets are usually used as the power mechanism. However, it is found in practice that the stroke and operating speed of this device cannot be adjusted, which may easily cause the circuit breaker handle to break. damage
In addition, this device also has certain limitations in the adjustment of the operating direction and the dust protection of the device itself.

Abstract

The invention provides an automatic device for breaker short-circuit open / close test, which comprises a support, a driving cylinder fixed on the support, a soft connection component and a control device; wherein the driving cylinder is fixed on the handle of a breaker on the support to realize the power of disjunction when in operation; the soft connection component is used for connecting the breaker handle and the axis of the driving cylinder; and the control device is used for controlling the motion of the driving cylinder, so as to drive the breaker to open and close.

Description

technical field [0001] The invention relates to an automatic device for short-circuit closing and opening tests of circuit breakers. The automatic device is applicable to circuit breakers with push-pull handles of various specifications. Background technique [0002] According to the relevant provisions of the national standard GB14048 and the international standard IEC60947, in the short-circuit test of the circuit breaker, the test object is required to be closed to generate a short-circuit current, so as to test the short-circuit making ability and short-circuit breaking ability of the circuit breaker. [0003] At present, some domestic test stations usually use manual operation in practice: a rope is fixed on the handle of the circuit breaker, and the operator pulls the rope outside the test room to drive the handle to close. This method is relatively primitive, takes up manpower, has certain risks, and it is difficult to meet the requirements of the relevant standards f...
