Description
Technical field
This utility model relates to a kind of electric component, be particularly suitable for big current outdoor high voltage isolator divide, use of closing a floodgate
Have strengthen contact pressure structure of contact terminal.
Background technology
The contact form that outdoor high-voltage isolating switch divides, close a floodgate has many types, but the overwhelming majority is to insert with contact
Enter in fingertip, and realize combined floodgate with fingertip compression contact.At present, the contact pressure of fingertip is all dependent on being located on fingertip
Spring produces.Under the conditions of out of doors, owing to being affected by factors such as variations in temperature, environmental pollution and the heatings of contact own, naked
Dew spring in an atmosphere is easy to cause fatigue and corrosion, causes elastic force to weaken, thus reduces the contact pressure between contact.This
In the case of Zhong, passing through if running into fault current again, the contact of disconnecting switch, the contact point of fingertip will be burnt, time serious
Contact can be burnt and cause power outage.
Summary of the invention
The purpose of this utility model is to provide a kind of structure of contact terminal having and strengthening contact pressure, and it is dependent on contact knot
The electric power that structure self produces, it is achieved strengthen the contact pressure between moving contact and static contact finger.
Technical solution of the present utility model is: a kind of have strengthen contact pressure structure of contact terminal, including moving contact,
Static contact finger, moving contact compression spring, it is characterised in that two static contact fingers being symmetricly set on conducting bracket are U-shaped, and U-shaped is quiet
The outboard end of fingertip is fixed on conducting bracket, and is connected with conductive strips, and the inner surface of inner side is provided with insulating base, moving contact pressure
Power spring one end is against on insulating base, and the other end is against on conducting bracket, and conducting bracket and conductive strips are connected on patch panel, dynamic
When contact is in closing position, its two ends contact surface is against on the interior aspect face of static contact finger respectively.
The structure of contact terminal that this utility model provides, is that two symmetrically arranged static contact fingers are designed to U-shaped, U-shaped static contact finger
Outboard end be fixedly connected on conducting bracket, be connected with patch panel by conducting bracket and conductive strips, formed electric pathway.Stationary contact
The active force of moving contact compression spring is born in the inner side referred to, is in close contact with the moving contact being in closing position.Work as structure of contact terminal
When being in "on" position, electric current flows through U-shaped static contact finger, and the medial and lateral electric current of static contact finger is incorgruous flowing, and the magnetic field of generation makes U
The both sides of shape static contact finger are mutually exclusive, owing to the outside of static contact finger is fixed on conducting bracket, therefore only produce inside static contact finger
Raw repulsive force, repulsive force and spring force jointly act on moving contact, thus enhance connecing between static contact finger and moving contact
Touch pressure, it is ensured that structure of contact terminal can reliable and stable operation under any environmental condition.
Feature of the present utility model is: have employed U-shaped static contact finger structure, when contact runs, static contact finger can produce one
Fixed repulsive force acts on moving contact, and the repulsive force of the biggest generation of electric current is the biggest, thus enhances static contact finger and moving contact
Between contact pressure, it is ensured that structure of contact terminal can reliable and stable operation under any environmental condition.This structure of contact terminal is the suitableeest
It is combined on heavy current disconnecting switches use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
Figure gives the structure of contact terminal being made up of a moving contact 5 and upper and lower symmetrically arranged a pair static contact finger, contact
Size and parameter etc. be that the size according to running current determines.Static contact finger 1 uses U-shaped structure, upper and lower static contact finger symmetry to set
Put on conducting bracket 6, illustrate as a example by one of them static contact finger, with bolt 2, the outboard end of static contact finger is fixed on Huang
On the conducting bracket that casting in bronze becomes, the outboard end of static contact finger is also associated with conductive strips 8, conducting bracket and conductive strips and is connected to connect simultaneously
On line plate 7.Connecting on inner surface inside static contact finger has insulating base 4, moving contact compression spring 3 one end to be against on insulating base, separately
One end is against on conducting bracket.The patch panel side of structure of contact terminal is fixedly mounted on contact supporting 9 by bolt 11, contact supporting
It is fixed on support insulator 10.In figure, moving contact 5 is in closing position, i.e. moving contact is manoeuvred into upper and lower being symmetrical arranged
Static contact finger in overturn the "on" position of 90 ° again, moving contact two ends contact surface is against on the outer surface inside static contact finger respectively, and
Under the effect of moving contact compression spring, moving contact two ends are compressed, be maintained at "on" position.
After disconnecting switch runs energising, the electric current I of structure of contact terminal is by the direction flowing of diagram, first from conducting rod (figure
Be not given) enter into moving contact 5, it is then divided into two-way and flows through from upper and lower static contact finger respectively, through conductive strips to patch panel, then from
Patch panel 7 flows out.After electric current enters static contact finger, electric current passes through along U-shaped loop, now, and the inside and outside effluent of same static contact finger
The sense of current of warp is contrary, during according to two adjacent current－carrying conductors by heterodrome, and the electricity produced under the influence of a magnetic field
Power makes the principle that two conductors are mutually exclusive, produces mutually exclusive power on static contact finger, leads owing to the outside of static contact finger is fixed on
On electricity support, repulsive force is all applied on moving contact by the inner side of static contact finger, so that the pressure that static contact finger is to moving contact
Increase, and along with the electrodynamic increase of the increase of electric current, the pressure of moving contact is strengthened by static contact finger the most therewith.
