Problems solved by technology

However, since the above clearance control is performed manually, errors may occur depending on each operator
Also, even if the same operator performs gap control, errors may occur depending on individual products
The time-delay operating characteristics of the circuit breaker may be affected by such errors, which may degrade the quality of the circuit breaker
[0014] Also, if the process is done manually, it also takes a lot of time for gap control
this can reduce productivity

Embodiment Construction

[0038] A detailed description will now be given of exemplary embodiments with reference to the accompanying drawings. For brief description with reference to the drawings, the same or equivalent components will be provided with the same reference numerals and description will not be repeated.

[0039] figure 1 is a schematic diagram of a circuit breaker according to the invention.

[0040] refer to figure 1 , the circuit breaker 100 includes a housing 10 configured to accommodate components therein. The case 10 is molded from an insulating material and is configured to insulate its inside from the outside. This structure is common, and therefore, its detailed description is omitted here.

[0041]Provided in the housing 10 are: a switch mechanism 20 configured to switch on / off a circuit; a terminal portion 50 including a fixed contactor 51 and a movable contactor 52 to which a power supply and a load are respectively connected 51 and movable contactor 52; detection mechani...

Abstract

Disclosed is a method for controlling a gap in a circuit breaker (100), the circuit breaker configured to interrupt a circuit by separating a movable contactor (52) from a fixed contactor (51) as a cross bar (33) is pressed to be rotated by a pressing member (32) due to bending of a bimetal (31), the method including: a gap forming step (S100) of bending the bimetal (31) by applying a set current, in a state where the pressing member (32) is coupled to a coupling hole (35) so as to be freely-movable, the coupling hole (35) formed at an upper part of the bimetal (31); and a gap fixing step (S200) of interrupting the set current when a prescribed time has lapsed, and of welding the pressing member (32) to the bimetal (31).

Description

technical field [0001] The present disclosure relates to a circuit breaker, and in particular, the present disclosure relates to a method for controlling a gap in a circuit breaker that detects an accident current and interrupts a circuit, the method being capable of passing a detection mechanism, for time The delay operation feature automatically sets the gap between the bimetal and crossbar. Background technique [0002] Circuit breakers are used to open or close loads in power substations or circuit lines, etc., or to interrupt current flow in the event of accidents such as ground faults or short-circuit currents. The circuit breaker converts the state of the circuit into the "off" or "on" state according to the user's operation. When overload and short-circuit current occur in the circuit, the circuit breaker interrupts the circuit to protect the load and the circuit. [0003] The circuit breaker has a time-limited trip characteristic and an instantaneous trip characte...
