Abstract
The utility model discloses a circuit breaker with a leakage protector, which is characterized in that conducting wires extracted from the circuit breaker are mutually connected with conducting wires extracted from the leakage protector, passing through holes on a cover shell of the circuit breaker and a seat shell of the leakage protector and running through a zero sequence mutual inductor in the leakage protector. The cover shell face of the circuit breaker is just matched with the seat shell face of the leakage protector; the height and the width are consistent; the cover shell face and the seat shell face are installed into one body. The utility model has the characteristics of small volume, beautiful appearance, convenient installation, safety, etc. The circuit breaker with a leakage protector can be used for personal electric shock and equipment leakage protection, overload and short circuit protection and non frequent conversion.
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.
" new product that has occurred since factory has used electric equipment handbook (hydraulic and electric engineering publishing house, Beijing, July nineteen ninety) typing always nineteen eighty-three is to the detailed introduction of contrasting of earth leakage protective device and low-voltage circuit breaker.Earth leakage protective device is to be mainly used to the person that fatal risk is arranged got an electric shock protect, and prevents the fire incident that causes because of electric equipment or line electrical leakage.Earth leakage protective device is threaded off to classify by it and can be divided into two kinds of electromagnetic type and electronic types.Electronic type is after instrument transformer detects signal and amplifies by the electronics amplifying circuit, to trigger controllable silicon or turn-on transistor switching circuit, connects the leakage tripping device coil and makes the earth leakage protective device action.Low-voltage circuit breaker in circuit mainly as the overload and the short-circuit protection of illumination, power-equipment and circuit.The DZ47 Series Circuit Breakers is for the small-sized plastic-shell formula, be made up of plastic casing, operating mechanism, contact system, arc quenching system and overcurrent trip etc.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.
Can both provide earth leakage protective device and circuit breaker (as DZ47 series) on the market now.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 as other, make troubles for like this electrician when mounted, and volume is not only big but also not attractive in appearance.
The purpose of this utility model provides and a kind ofly both can be used as that the person gets an electric shock and the usefulness of equipment earth leakage protective, can be used for illuminating line again and transship and short-circuit protection, and under even in everyday situations as the circuit breaker of the usefulness of the not frequent transitions of circuit.
In order to achieve the above object, the solution of the utility model employing is: the utility model is made up of circuit breaker (as the DZ47 type) and earth leakage protective device two parts.The lead of drawing in the circuit breaker 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 breaker cover shell and earth leakage protective device seat shell a gangbar is set, gangbar not only can drive the release of circuit breaker but also can drive the release of earth leakage protective device.When moving as earth leakage protective device, release drives gangbar, and gangbar drives the dropout of circuit breaker tripping device and opens circuit.
The utility model is compared with the external assembly unit situation of circuit breaker and earth leakage protective device, has that volume is little, a good looking appearance, easy for installation, safe and reliable advantage.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Accompanying drawing 1 is the stereogram of present embodiment.
Accompanying drawing 2 is the internal wiring schematic diagrames after present embodiment separates.
Present embodiment is made up of circuit breaker (1) and leakage switch (2).Circuit breaker (1) is the DZ47 type, just a turnover line is drawn in the hole, joins with the lead of drawing of leakage switch (2).Leakage switch (2) is made up of plastic casing, leakage tripping device, integrated circuit electron-amplifier, zero sequence current mutual inductor, test button, resistance etc.Inner leakage tripping device and the inner release of circuit breaker (1) of leakage switch (2) links with a gangbar (3).The seat shell face of the lid shell face of circuit breaker (1) and leakage switch (2) cooperates just, highly, the width unanimity, installs in aggregates.
Claims (2)
1, a kind of circuit breaker with earth leakage protective device; it is made up of earth leakage protective device and circuit breaker; it is characterized in that: the lead of drawing in the circuit breaker 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.
2, according to right 1 described a kind of circuit breaker, it is characterized in that with earth leakage protective device; The seat shell face of the lid shell face of circuit breaker and earth leakage protective device cooperates just, highly, the width unanimity, installs in aggregates.
