Abstract
The utility model discloses a contact knife compression structure of a isolation switch. The structure is a curved steel spring plate; the steel spring plate is compressed through a bolt, and the steel spring plate directly compress a contact knife. The isolation switch is electrified to generate heat during the operation process of the contact knife compression structure; the steel spring plate can not be deformed under the condition of allowable temperature rise and a certain of time, and the good contact between the contact knife and a contactor is not influenced. The contact knife compression structure has the advantages of simple production, convenient regulation and strong applicability, and can better meet the compression of the switch contact knife.
Description
Technical field
The utility model relates to a kind of power distribution isolating switch, and is special relevant with the contact compressing structure with the contact knife of isolating switch.
Background technology
High voltage isolator is the device that isolation under the non-loaded state of circuit, connection, conversion electrified body and electric device are got in touch in the electrical power distribution system.Existing its contact knife of optional isolating switch is to cooperate with spring, magnetic padlock plate and bolt with the contact compressing structure, comes holddown spring and magnetic padlock plate with bolt, makes spring compression magnetic padlock plate, and the magnetic padlock plate compresses contact knife, makes that contact knife and contact are intact to be contacted.But in running, isolating switch energising produces heat, and spring to a certain degree with under the time produces distortion being heated, and contact knife can not intactly be contacted with contact, can cause the major accident of distribution system in the time of seriously, causes isolating switch to burn.
The utility model content
The purpose of this utility model is that a kind of temperature rise of design is not yielding, the switch touching knife of contact stabilization and contact compressing structure.
The technical solution of the utility model is: this isolation switch contact compressing structure is a curved steel spring plate, and by bolt holddown spring steel plate, steel spring plate directly compresses contact knife.
The isolation switch contact compressing structure that the utility model provides, in running, the isolating switch energising produces heat, and steel spring plate does not influence contact knife and contacts with contact is intact allowing can not produce distortion under temperature rise and the certain hour.Make simple, easy to adjust, applicability is strong, satisfied the switch contact knife better and compressed.
Description of drawings
Fig. 1 is existing switch touching knife compressing structure schematic diagram;
Fig. 2 is the utility model switch touching knife compressing structure schematic diagram.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, spring 2, magnetic padlock plate 3, contact knife 4, steel spring plate
As shown in Figure 2, the utility model switch touching knife compressing structure is a curved steel spring plate 4, and by bolt holddown spring steel plate, steel spring plate directly compresses contact knife.
This switch touching knife compressing structure guaranteeing on the existing contact knife compressing structure characteristics basis, and spring 1 structure that matches with magnetic padlock plate 2 is changed into with steel spring plate 4, and realization compresses contact knife 3, satisfies the required pressure requirement of switch contact knife.
Claims (1)
1, a kind of switch touching knife compressing structure, its characteristics are: it is a curved steel spring plate (4), and by bolt holddown spring steel plate, steel spring plate directly compresses contact knife.
