Electronic transducer bracket of low-voltage circuit breaker

Abstract

The invention discloses an electronic transducer bracket of a low-voltage circuit breaker, which is formed by splicing a first bracket, a second bracket and a third bracket; the first bracket and the second bracket which have U-shaped structures sheath at least two third brackets with horizontal H structures; the first bracket is composed of a side wall, and a top wall and a bottom wall which areextended with the same length along the same direction from two ends of the side wall; the second bracket is composed of a side wall, and a top wall and a bottom wall which are extended along the same direction from two ends of the side wall; the third bracket is provided with a side wall, and a top wall and a bottom wall which are extended along the direction of two sides from two ends of the side wall; the electronic transducer bracket can realize three-electrode and four-electrode assembling requirements of the electronic circuit breaker simply and easily; the installation and location of the transducer is accurate and lead wire routing is sequential.

Description

technical field [0001] The invention relates to an electronic release installed in a low-voltage circuit breaker, in particular to a bracket for fixing a transformer in the electronic release. Background technique [0002] Commonly used low-voltage circuit breakers are power distribution type, motor protection type, residual current protection type and electronic circuit breaker. The electronic low-voltage circuit breaker has functions such as overload long-time delay, short-circuit short-time delay, short-circuit instantaneous and undervoltage protection. It is more comprehensive in function than ordinary circuit breakers, and it provides more reliable protection for power distribution lines and electrical equipment; electronic The various functions of the circuit breaker are realized by the electronic release. The electronic release includes: transformers, circuit boards and actuators. Each pole of the circuit breaker has a transformer to detect the current status flowing ...

AI Technical Summary

Problems solved by technology

The transformers of the current electronic circuit breakers are generally directly positioned in the limit grooves matched with the base, so there are many limit structures on the base that cooperate with the transformers, and the defect is that the base is complicated

Any transformer has lead wires connected to the circuit board. The existing installation method makes the wiring messy, the connecting wires are not positioned, and the wires are easy to be damaged during assembly and are easy to touch the main circuit of the circuit breaker, causing potential safety hazards in the line.
