Abstract
The utility model discloses a miniature lightning-proof circuit breaker which comprises a miniature electric leakage circuit breaker (10) and a surge protector (20), wherein the electric leakage circuit breaker (10) comprises an operating mechanism (1), an electric leakage release (3), a circuit board (4) and a transformer (5), and the surge protector (20) comprises a lightning-proof varistor (6). As the surge protector (20) is provided with an independent packaging structure, the volume of the lightning-proof varistor (6) positioned in the surge protector can be greatly increased, and the ability to absorb lightning surge currents and the lightning-proof ability can be greatly improved, and the problem that the lightning-proof varistor (6) explodes due to excessive absorption of lightning stroke energy can be avoided. The miniature lightning-proof circuit breaker integrates the miniature electric leakage circuit breaker (10) and the surge protector (20), and the miniature electric leakage circuit breaker and the surge protector are seamlessly mounted and connected together side by side, so that the miniature lightning-proof circuit breaker has a simple structure and is convenient to mount. The miniature lightning-proof circuit breaker is widely applied to the field of various miniature lightning-proof electric leakage circuit breakers.
Description
Technical field
The utility model belongs to low-voltage electrical apparatus and lightning-protected product field, is specifically related to a kind of small-sized lightning protection residual current circuit breaker.
Background technology
Existing domestic type DZ47LE series small-sized electric leakage (lighning proof type) circuit breaker has electric leakage, overload, short-circuit protection function and lightning protection function to a certain degree; its product is on the basis of DZ47LE residual current circuit breaker; the volume of the piezo-resistance in the electronic circuit is increased; be used for the overvoltage of absorption circuit, thereby reach the purpose of lightning protection.As shown in Figure 1, small-sized electric leakage (lighning proof type) circuit breaker comprises operating mechanism 1, piezo-resistance 2, leakage tripping device 3, wiring board 4, instrument transformer 5, and the operation principle of the prior art is a known technology, repeats no more.
The weak point of this technology is: (1) lightning protection capability deficiency.Rely on piezo-resistance 2 to absorb surge current, owing to be limited by the installing space of piezo-resistance 2, the finite volume of piezo-resistance 2 causes its scarce capacity that absorbs surge current, i.e. lightning protection capability deficiency; (2) security reliability is poor.Volume just because of piezo-resistance 2 is big inadequately, is being struck by lightning moment, and super-large current can cause the piezo-resistance blast, brings potential safety hazard, can not satisfy normal lightning protection demand.
The utility model content
At the deficiencies in the prior art, a kind of small-sized lightning protection circuit breaker of the special proposition of the utility model with defencive functions such as overload, short circuit, lightning protection.
Addressing the above problem the technical scheme of taking is: a kind of small-sized lightning protection residual current circuit breaker, to form by small-sized residual current circuit breaker 10 and Surge Protector 20, and described residual current circuit breaker 10 comprises operating mechanism 1, leakage tripping device 3, wiring board 4, instrument transformer 5; Described Surge Protector 20 comprises lighning proof type piezo-resistance 6.
Above-mentioned residual current circuit breaker 10 is the special-purpose small-sized residual current circuit breaker of CFJ65 series, because of it is a universal component, so its concrete structure and operation principle are repeated no more.
Above-mentioned Surge Protector 20 mainly comprises lighning proof type piezo-resistance 6, and it is an individual packages structure with insulation crust, links together by lead and the seamless side by side installation of small-sized residual current circuit breaker 10.
The beneficial effects of the utility model are: the lightning protection ability that (1) is powerful.Because the individual packages structure of Surge Protector 20, the volume that is positioned at lighning proof type piezo-resistance 6 wherein can improve greatly, and the ability and the lightning protection capability that absorb the lightning surge electric current significantly improve; (2) safe and reliable.Because the lightning protection capability of lighning proof type piezo-resistance 6 significantly improves, can not produce the problem that lighning proof type piezo-resistance 6 is exploded because of excessive absorption thunderbolt energy; (3) compact conformation, easy for installation.The utility model is integrated miniature circuit breaker 10 and Surge Protector 20, the two seamless side by side installation links together, and compact conformation is convenient to install.
Because above-mentioned beneficial effect, the utility model is widely used in various small-sized lightning protection residual current circuit breaker field.
Description of drawings
Fig. 1 is the line principle schematic diagram of prior art;
Fig. 2 is the utility model line principle schematic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
With reference to Fig. 2, a kind of small-sized lightning protection residual current circuit breaker, comprise special-purpose CFJ65 small-sized residual current circuit breaker 10 of series and Surge Protector 20, the special-purpose small-sized residual current circuit breaker 10 of CFJ65 series mainly is made up of operating mechanism 1, leakage tripping device 3, wiring board 4, instrument transformer 5 etc.; Because of it is a universal component, so its concrete structure and operation principle are repeated no more.
Surge Protector 20 mainly comprises piezo-resistance 6; it is an individual packages structure with insulation crust; special-purpose CFJ65 small-sized residual current circuit breaker 10 of series and special-purpose Surge Protector 20 are connected with screw by rivet, and are electrically connected by lead, and the two is combined into an integral body side by side.Because the individual packages structure of Surge Protector 20, the volume of the lighning proof type piezo-resistance 6 that it is inner improves greatly, and it is strong to absorb the lightning surge current capacity, and lightning protection capability significantly improves, and can not produce the problem of piezo-resistance blast.
