The quick-tripping device is arranged between the adjacent modules, so as to lead an operating mechanism to carry out quick reaction and cut the short-circuit current to a short circuit and produce current limit effect and improve the breaking capacity of the low-voltage circuit breaker; the modularized design is adopted to lead the modules to have interchangeability; the rotational structures and the actuating ends are adopted, a mechanical signal is transmitted by the ejector rod, thereby being convenient for transmitting N-phase signals of a four-level circuit breaker and realizing N-phase protection.
Description
Technical field
The present invention relates to a utmost point or multipolar low-voltage circuit breaker, be specifically related to a kind of trip gear with modularization low-voltage circuit breaker of rapid-releasing function.
Background technology
An existing utmost point or multipolar low-voltage circuit breaker comprise the housing that base, base and cover are formed, and are installed in a utmost point or multipole contact device in the housing, realize the operating mechanism and the electromagnetic tripping apparatus of on/off switch.When circuit breaker was subjected to big current overload, the contact head in the contact apparatus was subjected to electrodynamic effect, and both repel; reach metering function; and then the action of the electromagnet portion in the electromagnetic tripping apparatus is hit fast, makes the circuit breaker disjunction, reaches the effect of protection circuit and equipment.Wherein, multipole whenever all might be subjected to the impact of short circuit current in extremely, so require every utmost point can both current limliting and the quick disjunction of electromagnetism.But the contact head phase repulsive interaction current limliting and the electromagnet portion in the electromagnetic tripping apparatus of being abutted against in the system of touching are moved when realizing disjunction, and operate time is long, and the short circuit breaking protective capability of circuit breaker is reached capacity, and is difficult to improve the disjunction class.In order to address this problem, to have adopted the guiding short circuit air flow to promote trip gear at present and improved breaking speed, to reach the breaking capacity of better current limitation effect and raising circuit breaker.But its defective is: have influence on the structure of contact modules, make contact modules lose interchangeability.When being applied to 4 utmost point circuit breakers, because N is at a distance of far providing same protection mutually to N from operating mechanism.
Summary of the invention
The objective of the invention is for solving low-voltage circuit breaker disjunction protective capability of the prior art easily saturatedly, the problem that the disjunction class is difficult to improve proposes a kind of quick-tripping device of low-voltage circuit breaker, is applied to 4 utmost point circuit breakers, not the interchangeability of influencing contactor module.
The technical solution used in the present invention is: housing is installed in the both sides in module, turntable is separately positioned in the respective housings and an end of turntable has the actuation ends of stretching out housing, two outer logical gas channels are respectively arranged in the housing, be provided with the piece that can under gas pressure, move in the gas channel, article two, outer logical gas channel is positioned at the both sides of turntable, block is set on turntable, and the push rod two ends of passing module are relative with block respectively close.
The invention has the beneficial effects as follows:
1, the present invention is installed between the two adjacent modules, makes operating mechanism carry out transient response cutting-off of short-circuit electric current to short circuit, produces current limitation effect, and has improved the breaking capacity of circuit breaker.
2, the present invention has adopted modular design, makes module have interchangeability.
3, adopt a turntable and actuation ends, transmit mechanical signal, can be advantageously used in the N phase signals transmission of 4 utmost point circuit breakers, realize protection the N phase by push rod.
