Abstract
Disclosed is a single-module double-pole breaking multifunctional residual current circuit breaker. A bimetal plate is mounted on the upper portion of a circuit board close to a bottom push board and disposed in a middle partition board, a cavity for holding a pressure sensitive resistor is arranged at the lower part of the middle partition board, the cavity is communicated with a cavity beside the circuit board, a wire on the circuit board penetrates through a groove on an arc slot of the circuit breaker and extends into a magnetic ring cavity at the lower part of an inlet end of the circuit breaker, and a magnetic ring is disposed in the magnetic ring cavity. The single-module double-pole breaking multifunctional residual current circuit breaker has the advantages that a circuit board cavity is high in volume due to novel design, a circuit board with a 14K pressure sensitive resistor can be disposed in the circuit board cavity, and accordingly electromagnetic compatibility of the circuit breaker can be enhanced.
Description
Technical field
The utility model relates to a kind of circuit breaker, particularly a kind of residual current circuit breaker.
Background technology
The bipolar multifunctional electric leakage circuit breaker that opens circuit of unimodular number in the past is because the defective in the design, can not vacate bigger space and place the piezo-resistance of 14K, cause electric properties such as circuit breaker electromagnetism compatibility not reach the national standard requirement, the arc quenching system that the bipolar multifunctional electric leakage that opens circuit of traditional unimodular number opens circuit is little, be difficult to cut fast arc, cooling electric arc, breaking capacity is poor.
Summary of the invention
At the deficiency of above-mentioned technical problem, the utility model provides a kind of novel unimodular number the bipolar multifunctional electric leakage circuit breaker that opens circuit.
To achieve these goals, technical solution adopted in the utility model is:
The bipolar multifunctional electric leakage circuit breaker that opens circuit of unimodular number, comprise housing, median septum, handle, tripping system, operating mechanism, arc quenching system, the arc quenching system bottom is provided with a cavity along the housing bottom inboard, wiring board places in the cavity, wiring board is equipped with bimetal leaf near push pedal top, the end, and bimetal leaf places in the median septum, and the median septum bottom has one to place the cavity of piezo-resistance, and this cavity communicates with the cavity on wiring board side, the wiring board upper conductor goes out the chase that is provided with on the arc groove by circuit breaker and extends to the magnet ring chamber that is located at bottom, circuit breaker end of incoming cables, and magnet ring is arranged in the magnet ring chamber, and N polar conductor and L polar conductor are received on the end of N utmost point end of incoming cables and current coil respectively in the magnet ring along the end of incoming cables madial wall;
The other cavity of wiring board is equipped with operating mechanism by striking sheet top, operating mechanism top is provided with moving device of wink, described wink, moving device was: handle is built-in with energy-storaging spring and wink is moved snap close, wink, moving tripping one end was enclosed within the circuit breaker stake, during work along arcuate movement, the other end places operating mechanism bottom, and the termination withstands on and pushes away on the spring, and wink moving tripping middle part has to be moved snap close wink and be interlockingly connected on a recess and the handle;
Described piezo-resistance is 14K.
The beneficial effects of the utility model: 1, the wiring board chamber is because innovative design, volume is big, can place be equipped with the 14K piezo-resistance wiring board, thereby can improve the Electromagnetic Compatibility of circuit breaker, and the requirement that can be up to state standards, unimodular number in the past is bipolar to open circuit multifunctional electric leakage circuit breaker because the defective in the design can not be vacated the piezo-resistance that 14K is placed in bigger space, causes electric property such as circuit breaker electromagnetism compatibility not reach the national standard requirement.2, top, wiring board chamber can be equipped with larger volume two arc-extinguish chambers; separate by median septum; be respectively the L utmost point and N utmost point arc extinguishing; the arc quenching system that the bipolar multifunctional electric leakage that opens circuit of the unimodular number that the volume ratio of this arc-extinguish chamber is traditional opens circuit is much bigger; can cut arc fast; cooling electric arc makes circuit breaker have earth leakage protective, has higher breaking capacity in the time of multifunction protections such as overvoltage protection.
