Description

Clapper type electromagnetic mechanism

Technical Field

The utility model relates to a low-voltage apparatus field, concretely relates to clap box-like electromagnetic mechanism.

Background

The circuit breaker is used as a switch which can provide functions of voltage loss, undervoltage, overload, short-circuit protection and the like, and can effectively improve the safety and reliability of low-voltage electric appliances and power lines. The device can be used for distributing electric energy, starting an asynchronous motor infrequently, protecting a power supply circuit, the motor and the like, automatically cutting off a circuit when serious overload or short circuit, undervoltage and other faults occur, generally does not need to change parts after breaking fault current, and has been widely applied; a short circuit protection mechanism, also called an electromagnetic mechanism, is usually provided in the circuit breaker, and when the current passing through the circuit breaker increases to a certain value, the electromagnetic mechanism causes the circuit breaker to trip rapidly, thereby achieving the circuit protection function.

The existing electromagnetic mechanism usually adopts thinner iron plate punch forming as a magnetic pole surface, when a short circuit occurs in a circuit, an armature is attracted with a magnetic yoke, and the armature pushes a lock catch to be unlocked, so that a system is tripped; however, since the magnetic resistance is large and the magnetic field passing through the magnetic pole surface is small, the armature has a slow action speed, and the circuit breaker cannot be quickly disconnected when short circuit of a small multiple occurs, and the circuit and the equipment cannot be reliably protected.

SUMMERY OF THE UTILITY MODEL

In order to overcome the deficiency of the background art, the utility model provides a stable operation's clapper formula electromagnetic mechanism.

The utility model discloses the technical scheme who adopts: the utility model provides a clapper type electromagnetic mechanism, its includes the casing, install yoke in the casing, articulated first armature and the elasticity piece that resets of installing in the casing and corresponding yoke top position, surface mounting has second armature on the first armature, elasticity piece one end that resets is connected the casing, first armature is equipped with downwardly extending and the installation pole of being connected with the elasticity piece other end that resets.

The surface of the first armature is provided with a mounting hole, and the second armature is provided with a mounting post inserted into the mounting hole.

The both sides of installation pole personally submit the cockscomb structure, elasticity resets and adopts the extension spring, elasticity resets and is the couple.

The casing is internally provided with a support, two ends of the first armature are provided with hinged shafts, the hinged shaft at one end of the first armature is arranged in the casing, and the hinged shaft at the other end of the first armature is hinged on the support.

The utility model has the advantages that: one end of a hinged shaft at two sides of the first armature is arranged on the shell, and the other end of the hinged shaft is arranged on the bracket; when a short circuit fault occurs to the circuit and the equipment, the armature iron rotates towards the magnetic yoke under the action of the magnetic field, and pushes the lock catch to act in the rotating process, so that the mechanism is unlocked, the circuit breaker is opened, the circuit is disconnected, and the circuit and the equipment are protected. After the circuit is disconnected, the armature loses the acting force of the magnetic field, and the armature returns to the initial position under the action of the return spring; according to the technical scheme, the thick second armature is added on the first armature, so that the magnetic field passing through the armature is enhanced, the action speed of the armature is increased, and a reliable protection effect is achieved on a line and equipment.

Detailed Description

The embodiments of the present invention will be further explained with reference to the accompanying drawings:

as shown in the figure, the clapper type electromagnetic mechanism comprises a shell 1, a magnetic yoke 2 arranged in the shell 1, a first armature 3 which is hinged in the shell 1 and corresponds to the position above the magnetic yoke 2, and an elastic reset piece 4, wherein a second armature 5 is arranged on the upper surface of the first armature 3, one end of the elastic reset piece 4 is connected with the shell 1, and the first armature 3 is provided with an installation rod 6 which extends downwards and is connected with the other end of the elastic reset piece 4; one end of a hinged shaft at two sides of the first armature is arranged on the shell, and the other end of the hinged shaft is arranged on the bracket; when a short circuit fault occurs to the circuit and the equipment, the armature iron rotates towards the magnetic yoke under the action of the magnetic field, and pushes the lock catch to act in the rotating process, so that the mechanism is unlocked, the circuit breaker is opened, the circuit is disconnected, and the circuit and the equipment are protected. After the circuit is disconnected, the armature loses the acting force of the magnetic field, and the armature returns to the initial position under the action of the return spring; according to the technical scheme, the thick second armature is added on the first armature, so that the magnetic field passing through the armature is enhanced, the action speed of the armature is increased, and a reliable protection effect is achieved on a line and equipment.

The surface of the first armature 3 is provided with a mounting hole 31, the second armature 5 is provided with a mounting post 51 inserted into the mounting hole 31, and the detachable mounting structure is adopted, so that the practicability is good.

The cockscomb structure is personally submitted to the both sides of installation pole 6, elasticity resets 4 and adopts the extension spring, elasticity resets 4 and is the couple, the couple of extension spring is hung on the installation pole, provides the pretightning force that resets for first armature, owing to be the cockscomb structure, and the couple keeps tensile state always and can not break away from the installation pole, and stability is good.
