Abstract
The utility model discloses a primary contact with high current-carrying ability, mainly comprising a box-like bracket, and is characterized in that at least two primary contacts are arranged in the box-like bracket. The utility model has reasonable structure and skilled design because a plurality of primary contacts are arranged in the box-like bracket, and a plurality of contact points are parallel connection, thereby enhancing the current-carrying ability. The utility model can change the number of the parallel connection contact point according to the switch current-carrying requirement so as to adapt to the requirement of a plurality of standards on-load tap-changer to current, and has great extension value.
Description
Technical field
The utility model relates to the appliance switch technical field, specifically, relates to a kind of main contact of on load tap changer.
Background technology
In existing on load tap changer, main contact has various ways, use more have following two kinds: 1, two contacts are housed at contact base, link to each other with contact base by being flexible coupling, contact base also plays the conducting function of current, pressure by spring during installation makes contact reliably contact with outer terminal, the conducting electric current.2, the fixed contact that the inboard is and moving contact switches, the outside is a contact chip, has to be flexible coupling between fixed contact and the contact chip to link to each other, the pressure by spring during installation makes contact chip reliably contact with outer terminal, the conducting electric current.From last introduction as can be seen, in the existing on load tap changer, main contact mostly is a contact, even two contacts are arranged, all there is independent structures separately each contact, equals two contact additions, and to rethink increase contact number, structurally intractable.Because the main contact contact is few, the electric current that can carry just is restricted.
Summary of the invention
The purpose of this utility model is, provides a kind of and can effectively overcome above-mentioned defective, multiconductor parallel connection, the main contact of the high current carrying capacity of increase current capacity.
For achieving the above object, the utility model adopts following technical scheme: a kind of main contact of high current carrying capacity, mainly form by the box-like support, and it is characterized in that: be provided with at least three main contacts in the box-like support.
Owing to adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is rational in infrastructure, be skillfully constructed, owing to be provided with a plurality of main contacts in the box-like support, the multiconductor parallel connection has increased current capacity, can be according to the requirement of switch current-carrying, change the collateral contact number,, have promotional value to adapt to of the requirement of many specifications on load tap changer to electric current.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a cross-sectional view of the present utility model.
Embodiment
Referring to accompanying drawing, the bottom of box-like support 20 is equipped with spring 50, and the top of spring 50 is provided with four main contacts 10, and the middle part of main contact 10 is provided with mounting hole 11, is equipped with pilot pin 40 in it, plays the contact point guiding effect.Wherein, the both sides of each main contact 10 are provided with and are flexible coupling 30, be flexible coupling 30 to turn up, by screw in compression in box-like support 20 outsides.The box-like support plays the effect of conducting electric current simultaneously.
