Description
Technical field
The utility model is related to technical field of electric equipment, specially a kind of power distribution cabinet circuit fuse protecting device.
Background technology
Current protection is exactly to make a kind of protected mode of protective device action when electric current is more than predetermined maximum.Protection
When electric current in original paper is more than some numerical value adjusted in advance, protective device starts, and the selectivity of safety action, makes breaker
Trip or provide alarm signal.
Most of current protective device is protected by the way of fusing, when excessive by the electric current of fusible link
When, a large amount of heat is generated, fusible link is fused, cuts off circuit, to protective current, however existing fusible link is when in use,
The time of fusing is longer, ineffective in the protection of circuit.
Utility model content
The purpose of this utility model is to provide a kind of power distribution cabinet circuit fuse protecting devices, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the utility model provides the following technical solutions：A kind of power distribution cabinet circuit fuse protection dress
It sets, including：Cylinder, rubber stopper, metal terminal, fuse rod, filling gas, the cylinder is cylinder, and cylinder upper and lower ends are
Opening, the rubber stopper are connected to the upper and lower ends of cylinder, are sealed between rubber stopper and cylinder, and the metal terminal is affixed
In rubber stopper, metal terminal is made of three parts, and respectively top, connecting pole and wiring circle, the connecting pole are located at
In the middle part of rubber stopper, the top is the sheet metal of circular arc concave surface, and top is fixed in the top of connecting pole, and the wiring circle is solid
It is connected on the tail portion of connecting pole, the fuse rod is arranged in inner barrel, and fuse rod both ends are respectively embedded into the top of metal terminal
In head, the filling gas is nitrogen, and filling gas is filled in inner barrel.
Further, the cylinder is made of transparent material.
Further, insulation sleeve is socketed on the rubber stopper, the insulation sleeve center is provided with threading
Through-hole.
Compared with prior art, the utility model has the beneficial effects that：The circuit fuse protecting device of the utility model, body
Product is small, may be coupled directly on circuit, and when in use, fuse rod generates heat fusing, melt simultaneously in the case of line short
In disconnected process, a large amount of heat heating filling gas is will produce, gas expansion squeezes out the rubber stopper at both ends, when rubber stopper squeezes out,
Fuse rod can be detached with the top of metal terminal, by circuitry cuts, this mode can early cut-off circuit, need not wait for molten
Disconnected stick is fully disconnected, and the time of disconnecting circuit substantially reduces, and ensure that the protecting effect of circuit.
The utility model has many advantages, such as that simple in structure, easy to use, using effect is good.
Description of the drawings
Fig. 1 is the utility model overall structure diagram；
