Abstract
A breaker with a creepage protector is provided, which is composed of a creepage protector and a breaker. The inner releases of the breaker of various phases use a link to communicate with each other, a link is arranged between the overcrust of the breaker sticking to the creepage protector and the seat of the creepage protector. The utility model is characterized in that: the input end inscribe lead and the connection end lead of the breaker cross the input end inscribe lead hole and the connection end lead hole on the seat shell and the cover shell of the front breaker to through a hole on the seat shell of the creepage seat shell, the input end inscribe lead crosses through the zero-sequence inductor in the creepage protector and combined with the connection end lead, then the power input ends of the breakers of each phase has crossed the zero-sequence inductor. Comparing with the external connection and assembly situation of the breaker and the creepage protector, the utility model has compact structure, small volume, beautiful appearance, convenient installation and safety and reliability.
Description
The utility model relates to a kind of circuit breaker switch, refers in particular to a kind of circuit breaker with earth leakage protective device.
Earth leakage protective device is mainly used to the person that fatal risk is arranged got an electric shock and protects, and prevents the fire incident that causes because of electric equipment or line electrical leakage.Electronic leakage protector triggers controllable silicon or turn-on transistor switching circuit after detecting signal and amplify by the electronics amplifying circuit with instrument transformer, connects the leakage tripping device coil and makes the earth leakage protective device action.Low-voltage circuit breaker mainly as the overload and the short-circuit protection of illumination, power-equipment and circuit, generally is made up of contact system, arc control device, free tripping mechanism, operating mechanism, overcurrent trip, under voltage (decompression) release, shunt release, auxiliary contact, shell or framework etc. in circuit.Circuit breaker has four kinds of one poles, two utmost points, three utmost points, four utmost points.Two utmost points, three utmost points, four-pole circuit breaker are on the basis of monopolar configuration, and inner release is linked with gangbar.At present, can both provide earth leakage protective device and circuit breaker on the market.If customer requirements is provided with in circuit and not only has earth leakage protective but also have in the protector for circuit cut-off overload, then must with leakage switch and circuit breaker is external be assembled into together.Because circuit is external as to take safe precaution measure, adds protective sleeve or safety guard etc. as other, make troubles for like this electrician when mounted, and volume is not only big but also not attractive in appearance.In order to overcome the defective of above-mentioned technology, the applicant had once designed " a kind of circuit breaker with earth leakage protective device " (ZL96203657), it is made up of earth leakage protective device and circuit breaker, it is characterized in that lead that circuit breaker draws is by hole on the breaker cover shell and the hole on the earth leakage protective device seat shell, pass the zero-sequence transformer in the earth leakage protective device, the lead of drawing with earth leakage protective device joins; Between the lid shell of circuit breaker and earth leakage protective device seat shell, a gangbar is set.This technology only is applicable to the occasion of single-phase circuit breaker band leakage switch.
Task of the present utility model is to provide a kind of circuit breaker with earth leakage protective device; multi-phase circuit breaker only is with an earth leakage protective device; compact conformation; volume is little; both can be used as the usefulness of person electric shock and equipment earth leakage protective; can be used for illuminating line overload and short-circuit protection again, and under even in everyday situations as the usefulness of the not frequent transitions of circuit.
For finishing above-mentioned task; the solution that the utility model is taked is: a kind of circuit breaker with earth leakage protective device; form by earth leakage protective device and circuit breaker; the inside release of each phase circuit breaker links with gangbar; between the lid shell of the circuit breaker that pastes mutually with earth leakage protective device and the earth leakage protective device seat shell gangbar is set; it is characterized in that; connect on the seat shell that lead and union end lead pass previous circuit breaker respectively in the input of circuit breaker and connect wire guide in the input of lid on the shell and the union end wire guide until the hole of passing on the earth leakage protective device seat shell, connect in the input lead pass zero-sequence transformer and union end lead in the earth leakage protective device engage be each mutually the power supply input of circuit breaker all passed through zero-sequence transformer.
The utility model is when normal operation; the phasor of each phase current and be zero; zero-sequence transformer secondary side no-output; when electric leakage (residual current) or person electric shock occurring, then induce residual current, after amplifying by the electronics amplifying circuit at the zero-sequence transformer secondary coil; the turn-on transistor switching circuit; connect the leakage tripping device coil and make the earth leakage protective device action, linked circuit breaker is threaded off and open circuit plays the earth leakage protective effect.The utility model is compared with the external assembly unit situation of circuit breaker and earth leakage protective device, has that compact conformation, volume are little, a good looking appearance, easy for installation, safe and reliable advantage.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Fig. 1 is the front view of present embodiment.
Fig. 2 is the back panel wiring schematic diagram after earth leakage protective device separates with circuit breaker.
As shown in Figure 1, present embodiment is to be with an earth leakage protective device by three single-phase circuit breakers are assembled.
As shown in Figure 2; a kind of circuit breaker with earth leakage protective device; form by earth leakage protective device 1 and circuit breaker 2; the inside release of each phase circuit breaker 2 links with gangbar; between the lid shell of the circuit breaker 2 that pastes mutually with earth leakage protective device 1 and 1 shell of earth leakage protective device a gangbar is set; it is characterized in that; connect on the seat shell that lead 3 and union end lead 4 pass previous circuit breaker 2 respectively in the input of circuit breaker 2 and connect wire guide 5 in the input of lid on the shell and union end wire guide 6 until the hole of passing on 1 shell of earth leakage protective device 7, connect in the input lead 3 pass zero-sequence transformer 8 and union end lead 6 in the earth leakage protective device 1 engage be each mutually the power supply input of circuit breaker 2 all passed through zero-sequence transformer 8.
