Abstract
The utility model discloses a contacting combining structure of the high voltage grounding switch knife and contact in the power distribution system. The contact (1) is designed to be a plane structure in the model, while the knife is designed to have two compressing springs outside. When the contact(1) and the knife(2) are closed together, the compressed spring(3) will pressed the switch knife(2) tightly, and the convex of knife(2) will be contacted with the surface of the contact(1) completely. The combining structure has the characteristics of simple design, low consumption and simple processing craft, and has guaranteed the combination of the knife and the contact.
Description
Technical field
The utility model belongs to electrical technology field, the contact matching structure of particularly a kind of high voltage ground switch contact knife and contact.
Background technology
High voltage ground switch is used for making system earth when circuit disconnects in electrical power distribution system, thereby guarantees being perfectly safe of construction or attendant.Existing high voltage ground switch contact knife and contact contact matching structure are that projection is arranged on the contact, and contact knife is a planar structure, close a floodgate when contacting at contact knife and contact, and stage clip compresses contact knife from both sides, and the projection of contact knife and contact is contacted.This contact matching structure can not guarantee the integrity that contacts of contact knife and contact, can cause the accident of distribution system when serious, even cause staff's injures and deaths.Complex structural designs, consumptive material are big, the processing technology difficulty is big.
The utility model content
The purpose of this utility model be design a kind of simple in structure, consumptive material is few, easy to process, and make the intact fit structure that contacts of high voltage ground switch contact knife and contact.
The technical solution of the utility model is such: with the earthed switch contact design is planar structure, the earthed switch contact knife is taked the belling structure, and stage clip is arranged on the outside of contact knife, when contact knife and contact close a floodgate when contacting, stage clip compresses contact knife from both sides, makes contact knife projection and contact plane contact.
The high voltage ground switch contact that the utility model provides and contact knife contact matching structural design is simple, consumptive material is little, processing technology is little has guaranteed contacting of contact knife and contact fully.
Description of drawings
Fig. 1 is existing high voltage ground switch contact knife and contact contact matching structural representation;
Fig. 2 is the structural representation of a utility model high voltage ground switch contact knife and an embodiment of contact contact matching structure.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, contact 2, contact knife 3, stage clip
In the embodiment shown in Figure 2, earthed switch contact 1 is a planar structure, and earthed switch contact knife 2 is provided with belling, and contact knife 2 arranged outside have two stage clips 3.When contact 1 closed a floodgate with contact knife 2, stage clip 3 compressed earthed switch contact knife 2 from both sides, and contact knife 2 contacts with contact 1 plane fully by the projection of self.
Claims (1)
- The contact matching structure of a kind of high voltage ground switch contact knife and contact, comprise contact (1), contact knife (2) and stage clip (3), it is characterized in that: earthed switch contact (1) is planar structure, and earthed switch contact knife (2) is provided with belling, and contact knife (2) arranged outside has two stage clips (3).
