An energy-saving circuit breaker

Abstract

The invention discloses an energy-saving circuit breaker, which includes a button, a return spring, a switch body, a main circuit conductor, a pull-in circuit and a first mutual inductor, the main circuit conductor includes a first wire and a second wire, and the first wire and a second wire The adjacent ends of the two wires have contacts and are located under the switch body. The ends of the first wire and the second wire that are far away from each other are used as external joints. The switch body includes a contact plate and a pull-in armature connected by a guide rod. The lower surface of the contact plate is provided with electrical contacts and is facing the contact at the adjacent end of the first wire and the second wire. The contact plate is connected to the button upwards, and the lower part of the button is also provided with a return spring. On one side, a pull-in circuit is arranged under the pull-in armature, and the pull-in circuit is connected with the first wire or the second wire through the first transformer, and the first transformer converts the main circuit current on the first wire or the second wire into The pull-in circuit becomes the drive current.

Description

technical field [0001] The invention relates to the field of circuit breakers, in particular to an energy-saving circuit breaker. Background technique [0002] The circuit breaker is an important part in the circuit, which is used for the safety protection of the circuit. [0003] In the prior art, the circuit breaker is only used to undertake the function of breaking the overcurrent, and the magnitude of the breaking current is inconvenient to adjust, and is usually fixed during manufacture. [0004] In the existing electrical technology, there is no simple switch component that can identify a small current and then break the circuit. In some applications, such a simple switch is actually needed, which can be safely broken after a power cycle is over. When the main circuit is turned on, only outside operators perform manual operations before starting the next cycle of work to prevent, for example, some components on the assembly line from starting, and these operations are...

[0003] In the prior art, the circuit breaker is only used to undertake the overcurrent breaking function, and the breaking current is inconvenient to adjust, and it is generally fixed during manufacture.

[0004] In the existing electrical technology, there is no simple switch component that can identify a small current and then break the circuit. In some applications, such a simple switch is actually needed, which can be safely broken after a power cycle is over. When the main circuit is turned on, only outside operators perform manual operations before starting the next cycle of work to prevent, for example, some components on the assembly line from starting automatically, and these operations are now generally realized through current sensors and automatic control, which is more troublesome
