Abstract

The utility model relates to a part of a low-voltage power transmission apparatus, and specifically relates to a low-voltage breaker buckle-releasing apparatus with reinforced insulation. The buckle-releasing apparatus comprises a coil, a bimetallic strip, a thermal element and a magnet yoke which are sequentially arranged on an insulation support from front to back. An arm portion of the magnet yoke goes through the coil. The bimetallic strip is fixed with the thermal element through riveted joint. The magnet yoke is fixed on an insulation support in a pressing holding mode through an upper insulating part. An insulating panel is arranged between the magnet yoke and the thermal element. The low-voltage breaker buckle-releasing apparatus with the reinforced insulation of the utility model is simple in structure and convenient to install. According to the low-voltage breaker buckle-releasing apparatus with the reinforced insulation of the utility model, installation modes of magnet yokes in traditional buckle-releasing apparatuses are changed, and direct conductive contact between the magnet yoke and the thermal element does not occur. Possible short circuits when the coil is damaged are avoided, and the reliability of thermal and magnetic buckle-releasing is raised.

Description

The low-voltage breaker tripper of reinforced insulation
Technical field
The utility model relates to a kind of parts of low voltage power transmission equipment, specifically a kind of low-voltage breaker tripper of reinforced insulation.
Background technology
The release of low-voltage circuit breaker is for realizing the functional part of low-voltage circuit breaker emergency trip under overload current and transient short-circuit current condition.An existing class adopts thermal element and the synergistic release of yoke, and the release as Chinese patent CN101976640A and Chinese patent CN101004987 all disclose has.It generally includes coil, bimetal leaf, thermal element and the yoke be arranged on insulating support.Thermal element connects successively bimetal leaf and coil forms current circuit, and thermal element and bimetal leaf are for being reacted overload current, and yoke and coil are for being reacted short circuit current.In this structure, before and after coil, bimetal leaf, thermal element and yoke, precedence is arranged, and the body of yoke and thermal element riveted joint are fixing usually, and the arm of yoke is from the side through coil.In its course of work, if coil has breakage can encounter yoke, cause short circuit, affect the reliability of release magnetic action; Can increase the assembling difficulty if increase insulating tape on yoke.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of low-voltage breaker tripper of simple in structure, easy for installation, reinforced insulation that Reliability of Microprocessor is high is provided.
Coil, bimetal leaf, thermal element and yoke that the low-voltage breaker tripper of reinforced insulation of the present utility model is arranged in order before and after including on insulating support, the arm of yoke is through coil, and bimetal leaf and thermal element riveted joint are fixing; Described yoke is fixed on insulating support by a upper insulating part pressure holding, is lined with one deck insulation board between yoke and thermal element.
Described insulation board and thermal element riveting.
The utility model is simple in structure, easy for installation, and the mounting means that it has changed yoke in traditional release makes yoke and thermal element that direct conductive contact not occur, and has avoided contingent short circuit when coil is damaged, has improved the reliability that thermal and magnetic is threaded off.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is decomposition texture schematic diagram of the present utility model.
Embodiment
As shown in the figure, coil 2, bimetal leaf 3, thermal element 4 and yoke 5 that the low-voltage breaker tripper of this reinforced insulation is arranged in order before and after including on insulating support 1, the arm of yoke 5 is through coil 2, and bimetal leaf 3 is fixing with thermal element 4 riveted joints; Described yoke 5 is fixed on insulating support 1 by upper insulating part 6 pressure holdings, between yoke 5 and thermal element 4, is lined with one deck insulation board 7.Insulation board 7 and thermal element 4 rivetings.
