Embodiment 1

[0021] In the embodiment of the present invention, an electromagnetic balance type residual current operated circuit breaker includes a casing 1 and a rotating roller 3 rotating in the casing 1 and connected to the push button 4 through a connecting rod assembly 2; one end of the rotating roller 3 The rotating shaft is fixed with the triangular piece 11 that abuts against the magnet 9, the upper and lower ends of the magnet 9 (the orientation is based on figure 2 Confirm) are respectively provided with two electromagnet assemblies, the upper electromagnet assembly is used to repel the magnet 9 downward, and the lower electromagnet assembly is used to repel the magnet 9 upward. When the electromagnet assembly is energized, the magnet 9 is in two In the middle of the electromagnet components, the upward repulsive force is equal to the sum of the gravity of the magnet 9 itself and the downward repulsive force, so that under normal conditions, the magnet 9 is in a static state. Wh...

Embodiment 2

[0030] In the specific implementation process of the present invention, another embodiment is proposed to further illustrate the circuit breaker, thereby increasing the integrity of the application. Specifically, the upper and lower ends of the housing 1 are respectively provided with a first terminal 5 and a The second connection terminal 6, the first connection terminal 5 is used for accessing external current, and the second connection terminal 6 is used for connecting household current.

Abstract

The present invention relates to a circuit breaker, in particular to an electromagnetic balance type residual current operated circuit breaker, which comprises a casing and a rotating roller which rotates on the casing and is arranged through the casing; The upper and lower ends of the magnet are respectively provided with two electromagnet assemblies, the upper electromagnet assembly is used to repel the magnet downward, and the lower electromagnet assembly is used to repel the magnet upward. Below, the magnet is in the middle of the two electromagnet components, and the upward repulsive force is equal to the sum of the magnet's own gravity and the downward repulsive force. The invention is novel in design. The balance of the magnet position is realized by two electromagnet components. When the circuit is short-circuited, the magnetic force of the electromagnet component can be changed instantaneously, thereby affecting the position of the magnet, and then realizing the reset rotation of the roller, thereby realizing instantaneous disconnection. Electricity, play a protective role, high security.

Description

technical field [0001] The invention relates to a circuit breaker, in particular to an electromagnetic balance type residual current operated circuit breaker. Background technique [0002] The residual current operated circuit breaker can quickly cut off the faulty power supply in a very short time to protect the safety of people and electrical equipment. Current-operated circuit breakers are suitable for AC 50Hz or 60Hz, rated voltage single-pole two-wire, two-pole 230V, three-level / three-four-wire, four-level 400V, rated current up to 60A, when personal electric shock or grid leakage current exceeds the specified When the value is high, the residual current operated circuit breaker can quickly cut off the fault power supply in a very short time to protect the safety of people and electrical equipment. The residual current operated circuit breaker has the function of preventing people from getting an electric shock. According to the IEC standard, when the human body passes...
