Abstract

The invention discloses a reclosure controller having an external electric leakage function based on an intelligent plastic shell. The reclosure controller comprises a sampling circuit, a microprocessor, a magnetic flow converter and an electric operating mechanism, wherein the input end of the sampling circuit is connected with the input end of the microprocessor, the output end of the microprocessor is connected with the input end of the magnetic flow converter, and the microprocessor is connected with the electric operating mechanism in a bidirectional mode. According to the reclosure controller, the functions can be achieved only with one breaker, and the structure is simple and practical.

Description

technical field [0001] The invention relates to a reclosing controller, in particular to a reclosing controller based on an intelligent plastic case with an external leakage function. Background technique [0002] Existing intelligent molded case circuit breakers only have overload protection, short-circuit short-time delay protection, and short-circuit instantaneous protection; while the residual leakage protection function is realized by an external leakage module on the side of the circuit breaker, without leakage reclosing function. The existing intelligent molded case circuit breaker has no leakage reclosing function. Contents of the invention [0003] The object of the present invention is to provide a reclosing controller with an external leakage function based on an intelligent plastic casing to address the defects in the prior art. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] The inventio...
