Abstract

The utility model relates to a novel fuse-type isolating switch, which consists of a base, a plastic cover and a protective cover. First screws, contact seats A, contact seats B, clamping pieces, second screws, wiring terminals, third screws, nuts, contact plates and square rods are additionally arranged on the base. The contact seats A and the contact seats B are respectively and tightly screwed on the nuts of the base through the first screws. The clamping pieces are respectively arranged beside the contact seats A and the contact seats B. The clamping pieces are clamped on the contact seats. The contact plates are connected with the contact seats A through the second screws. Two square rods are arranged below the base to tightly clamp the switch on a bus bar. The wiring terminals are fixedly arranged on the contact seats B through the third screws. The plastic cover can be opened or closed in a sector shape, is installed on the base through a hinge and can be fully removed out from the base. The protective cover is divided into an upper cover and a lower cover, wherein the upper cover and the lower cover are clamped in the base through bayonets. The novel fuse-type isolating switch has the advantages that not only can the novel fuse-type isolating switch be conveniently assembled and disassembled and can the installation space be saved, but also the state of a fusible core can be conveniently observed.

Description

A kind of new type fuse formula isolating switch

Technical field

The utility model relates to a kind of low voltage power transmission equipment, particularly a kind of fuse disconnecting switch.

Background technology

Fuse disconnecting switch is a kind of switch of power consumption equipment being protected through fusible core, and that this switch requires in use is deciliter simple, rapidly.

At present, existing fuse disconnecting switch generally includes the base that fixed contact is installed and the loam cake that moving contact is installed, and loam cake is hinged through a connector and base, the branch of the rotation realization switch through loam cake, closes.There is following defective mostly in the fuse isolating switch of existing structure:

1, the connector that is fixed on loam cake generally is exposed to the base side wall outside, in use by the parts of external equipment easily with its clamping stagnation, reduced the reliability of switch branch, combined floodgate.

When 2, existing operating personnel manually carry out branch, closing operation, because divide-shut brake speed is slower, between dynamic/static contact, produce electric arc easily, cause the contact damage, the equipment that influences normally uses.

3, existing fuse disconnecting switch loading and unloading fusible core is inconvenient, and is difficult for observing fault state.

The utility model content

The purpose of the utility model is: a kind of simple to operation, safe and reliable new type fuse formula isolating switch is provided, to address the above problem.

The utility model solves the technical scheme that its technical problem adopted:

A kind of new type fuse formula isolating switch is made up of base, vinyl cover and protective cover three parts, also comprises on the said base: first screw, touch base A, touch base B, holder, second screw, binding post, the 3rd screw, nut, contact plate, square bar; The position of touch base A and touch base B is symmetry up and down; Pass through first screw-driving respectively on the nut of base, touch base A and touch base B next door are respectively arranged with holder, and holder is clipped on the touch base; Said contact plate is connected with touch base A through second screw; Pass through first screw again on base, base has two square bars, and said square bar is clamped in switch on the busbar; Said binding post passes through the 3rd screw on touch base B; Said vinyl cover can be fan-shaped to be opened or closes, and through being hingedly mounted on the base, and can from base, withdraw from fully; Said protective cover is divided into cover and covers down; The said cover through bayonet socket up and down snaps in base, and the protection conductive pieces can not make the people touch.

Further, the switch installation form of the utility model adopts the bus mounting structure, can save installing space significantly like this.

Further, also be provided with a packing ring and a spring washer below said second spring.

Further, also be provided with spring A under the said contact plate.

Further, said square bar has spring B, and the outside is locked by tight locking button.

Further, also be provided with one the 4th screw on the base, but turn the 4th screw easy removal switch.

Further, said vinyl cover is provided with the key part, presses key part loading and unloading fusible core easily.

Further, be embedded with transparent panel on the said vinyl cover, can clearly observe fusible core fault whether situation through transparent panel.

Adopt the utility model to possess following advantage:

1, fusible core is loaded on the vinyl cover and directly forms electric loop behind the touch base as moving contact insertion base, and vinyl cover can break away from switch fully like this, the loading and unloading fusible core that can follow one's inclinations.

2, the key part is set on the vinyl cover, can loads and unloads fusible core easily, time saving and energy saving, one by getting final product.

3, on the vinyl cover transparent panel is set, sees through the situation that transparent panel can clearly be observed fusible core.

4, be provided with the 4th screw that is used to load and unload switch specially, as long as turning the 4th screw from the front just can load and unload switch like a cork, and needn't be around go dismounting at the back to regulator cubicle.

5, the switch installation form of the utility model adopts the bus mounting structure, can save installing space significantly like this.
