Embodiment Construction

[0028] Such as Figure 1-Figure 4 As shown, the specific embodiment of the present invention is an intelligent miniature circuit breaker, which includes a housing 1 and a handle 2, an operating mechanism 3, a tripping mechanism 4, an electric opening and closing mechanism 5, and a handle set in the housing 1. The thickness of 1 is a modulus of 18mm. The housing 1 is made up of a base and an upper cover. The operating mechanism 3 and the tripping mechanism 4 are arranged oppositely in the housing 1. The tripping mechanism 4 includes a contact plate 41 and a tripping mechanism. The armature 42, the armature 43, and the suction plate 44 are arranged in parallel on the outer surface of the contact plate 41. The two sides of the armature 43 extend to the inner side of the contact plate 41 to form a hinge seat 431. A hinge hole 432 is formed in the hinge seat 431. One end of the suction plate 44 A hinge shaft 441 is extended to both sides. The hinge shaft 441 is inserted in the hinge...

Abstract

The invention relates to an intelligent miniature circuit breaker which comprises a shell and a handle, an operating mechanism, a tripping mechanism and an electric breaking-closing mechanism which are arranged in the shell, wherein the electric breaking-closing mechanism comprises a circuit board, a motor, a worm, a turbine, a linkage gear, a driving gear and a handle gear; a metering unit is arranged on the circuit board, the circuit board is arranged between the tripping mechanism and the shell, the motor is arranged on the circuit board, the worm is connected to an output shaft of the motor and is in linkage connection with the linkage gear and the driving gear by the turbine, the turbine and the linkage gear are arranged between a contact board and a circuit board, a section driving gear is fixed on the driving gear and is meshed with the handle gear, the handle gear is a section gear and is coaxially connected with a handle, and the handle is connected with a jump pin by a connecting rod. According to the invention, the functions of electric energy metering, short circuit protection, electronic protection, fee-controlled breaking and automatic reclosing are realized in one module.

Description

Technical field [0001] The invention relates to a low-voltage electrical switch, in particular to an intelligent miniature circuit breaker with functions of short-circuit protection, electronic protection, electric energy metering, cost control breaking and automatic reclosing. Background technique [0002] The intelligent miniature circuit breaker is a mechanism that controls the breaking of the circuit breaker through electrical signals. The existing circuit breakers generally use electromagnetic releases for short-circuit protection. The single function of this electromagnetic release can only correspond to short-circuit and over-current protection, which cannot meet current requirements. More and more intelligent electrical control protection requirements. Summary of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides an intelligent miniature circuit breaker with comprehensive functions and simple structure. [0004] In ord...
