Abstract
An anti-thunder circuit breaker. An over-current protection circuit and a heat tripping mechanism are connected between input and output of every phase. A contact of the heat tripping mechanism and the output are grounded though Anti-thunder circuit composed of a varistor. The utility model which put the function of a surge protective device into the circuit breaker has the advantages of simple and compact structure, decreasing cost, fixing and using very conveniently and reliable lighing protection performance. Specification and geometry of the Anti-thunder circuit breaker can be made as the current Anti-thunder circuit breaker, so it is convenient to be matching, and installation space needed decreases.
Description
Technical field: the utility model relates to a kind of circuit breaker.
Background technology: general circuit breaker need connect surge protector at output if avoid the damage of thunder and lightning to circuit.Present surge protector all is the split acyclic type, wants plural parallel stage to install when connecting multi-phase circuit breaker, and wiring is pretty troublesome, in distribution box to take installing space big, shape-designing and circuit breaker do not match yet, and external surge protector makes the equipment cost increase.
Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of compact conformation, lightning protection circuit breaker easy to install.
Circuit breaker of the present utility model all is connected with current foldback circuit and crosses thermal tripping mechanism between the input of each phase, output, this crosses the lightning protection circuit ground connection of contact by being made up of piezo-resistance of thermal tripping mechanism and output.
The utility model is incorporated into the function of surge protector in the circuit breaker; constitute the lightning protection circuit breaker of integral type; compact conformation is simple; install and use very convenient; lightning protection properties is reliable, reduce cost, and form factors can be made into the same with present circuit breaker; be convenient to supportingly, the installing space that needs reduces.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is the circuit block diagram of embodiment;
Fig. 2 is the circuit connection diagram of embodiment.
Embodiment: as shown in the figure, all be connected with current foldback circuit 1 and cross thermal tripping mechanism 2 between the input of each phase, output, this crosses the lightning protection circuit ground connection of contact by being made up of piezo-resistance 3 of thermal tripping mechanism 2 and output.Present embodiment organically combines circuit breaker and surge protector, during installation external cabling very convenient, performance meets the lightning protection standard, and both are in conjunction with making current foldback circuit 1, crossing thermal tripping mechanism 2 and piezo-resistance 3 protect mutually, the raising reliability.In fact, also can comprise in the lightning protection circuit and the gas discharge tube 4 of piezo-resistance 3 series connection, can prevent leakage current like this, the lightning protection circuit better reliability.
Claims (2)
1, a kind of lightning protection circuit breaker all is connected with current foldback circuit and crosses thermal tripping mechanism between the input of each phase, output, it is characterized by: this contact of crossing thermal tripping mechanism (2) and output passes through the lightning protection circuit ground connection be made up of piezo-resistance (3).
2, lightning protection circuit breaker according to claim 1 is characterized by: also comprise in the lightning protection circuit and the gas discharge tube (4) of piezo-resistance (3) series connection.
