Abstract
The utility model relates to a prepayment small-sized circuit breaker which comprises an arc extinguish chamber, a base, magnetic conducting plates, an electromagnetic system, a lock catch, a filament spring, a null line arc extinguish chamber, a U-shaped connecting rod, a lower flash barrier, a prepayment circuit board, a prepayment shunt excitation coil and the like, wherein the null line arc extinguish chamber is arranged between a moving contact on the electromagnetic system and a fixed contact on a fixed contact component; the null line arc extinguish chamber can be divided into four or six sheets; one end of the filament spring penetrates through the base and is positioned between the fixed contact component and the lock catch, and the other end of the filament spring is connected with the prepayment circuit board; the magnetic conducting plates are positioned at the two ends of the electromagnetic system and are connected with magnetic conducting plates; one end of the U-shaped connecting rod is connected with a handle, and the other end of the U-shaped connecting rod is connected with a jump pin; and one end of the prepayment shunt excitation coil is connected with an input end, and the other end of the prepayment shunt excitation coil is connected with a circuit arranged in the prepayment circuit board. The prepayment small-sized circuit breaker reduces the damage to a null line contact and the fixed contact during segmentation, and improves the breaking capacity of products.
Description
Technical field:
The utility model relates to a kind of miniature circuit breaker, and particularly a kind of pre-payment miniature circuit breaker has the zero line of minimizing contact, the damage of fixed contact in the time of segmentation, has improved the characteristics such as breaking capacity of product.
Background technology:
Circuit breaker is deciliter switch that is used to control electric loop as a kind of control electric installation, protection circuit and power supply under overload, short circuit and under voltage situation.When existing circuit breaker was carried closed and disconnected at band, arc chamber was prone to produce electric arc, thereby makes zero line moving contact, fixed contact when disjunction, produce damage, has reduced the breaking capacity of product.
The utility model content:
Technical deficiency to existing the said goods; The purpose of the utility model just provides a kind of pre-payment miniature circuit breaker, and it is made up of arc control device, pedestal, magnetic conduction sheet, electromagnetic system, snap close, filament spring, zero line arc control device, U-shaped connecting rod, following flash barrier, pre-payment wiring board, pre-payment shunt opening coil etc.
The utility model solves the technical scheme that its technical problem adopted: the zero line arc control device are located between the moving contact and the fixed contact on the fixed contact assembly on the electromagnetic system, and the zero line arc control device can be four or six; Filament spring one end passes pedestal between fixed contact assembly and snap close, and the other end links to each other with the pre-payment wiring board; Magnetic conduction sheet is positioned at the electromagnetic system two ends, links to each other with magnetic conductive board; U-shaped connecting rod one end connects handle, and the other end connects tripping; Pre-payment shunt opening coil one end connects input, and the other end connects pre-payment wiring board internal circuit.
The utility model beneficial effect: have the zero line of minimizing contact, the damage of fixed contact in the time of segmentation, improved the breaking capacity of product.
