Abstract
The utility model relates to a moving contact mechanism for a compound vacuum loaded tap switch, which comprises a primary contact and a secondary contact, wherein, a transition resistance is arranged between the primary contact and the secondary contact. One vacuum switch tube is respectively serially connected between the primary contact and the transition resistance and between the secondary contact and the transition resistance. The moving contact mechanism adopts a vacuum switch tube to extinguish arc so the utility model has the advantages of good effect, transformer oil saving and operating cost reducing.
Description
The utility model relates to a kind of dynamic contact mechanism that is used for compound vacuum on-load operation switch.
Compound on load tap changer is used for selecting to be connected with the tap of switching transformer at load condition, realizes on-load voltage regulation.Its structure comprises that having the switch of selecting with handoff functionality concurrently inserts core, insulating cylinder, quick mechanism and operating mechanism.Quick mechanism and operating mechanism are installed on the dividing plate of switch insertion core, switch inserts core and inserts insulating cylinder, fixed contact is installed on the insulation barrel, dynamic contact mechanism is installed on the main shaft that inserts core, main shaft can rotate, order about moving contact by the contact of set program and fixed contact with separate, finish the switching of circuit.Dynamic contact mechanism comprises a main contact (during normality and fixed contact closure) and secondary contact (during normality and fixed contact throw off), is connected to the transition resistance of using when switch switches between main contact and secondary contact.This dynamic contact mechanism need be immersed in the transformer oil and switch, and transformer oil need regularly replace as arc-extinguishing medium, and the maintenance trouble has increased operating cost.The useful life that arc extinguishing has also reduced contact in oil simultaneously.
The purpose of this utility model provides a kind of dynamic contact mechanism of arc extinguishing in a vacuum, is applicable to compound vacuum on-load operation switch.
The dynamic contact mechanism that the utility model proposes comprises a main contact and a secondary contact, between main contact and secondary contact, be connected to transition resistance, it is characterized in that between main contact and the transition resistance and secondary contact and transition resistance between be connected in series 1 vacuum switch tube respectively.
The dynamic contact mechanism of this practical proposition is rational in infrastructure, and the electric arc that moving contact and fixed contact produce in handoff procedure is gone out in vacuum switch tube to be removed, respond well, has saved transformer oil, has reduced operating cost.
Followingly concrete enforcement of the present utility model is further described with reference to accompanying drawing.
It shown in the accompanying drawing phase dynamic contact mechanism cutaway view that reality is had on-load shunting switch in vain.
This dynamic contact mechanism comprises main contact (1) and secondary contact (2), be connected to transition resistance (6) between main contact (1) and the secondary contact (2), it is characterized in that between main contact (1) and the transition resistance (6) and secondary contact (2) and transition resistance (6) between be connected in series 1 vacuum switch tube (5) respectively.Vacuum switch tube (5) is an existing product, main contact (1) and secondary contact (2) are individually fixed in the upper and lower side of fore-stock (3), the front end of 2 vacuum switch tubes (5) directly contacts with secondary contact (2) with main contact (1) respectively, vacuum switch tube (5) and main contact (1), spring (4) is housed between the secondary contact (2), the rear end of 2 vacuum switch tubes (5) is individually fixed in the upper and lower side of after-poppet (7), the rear end brace (8) of 2 vacuum switch tubes (5) is connected with the two ends of transition resistance (6) respectively, transition resistance (6) is evenly on fore-stock (3) and after-poppet (7), fore-stock (3) is separately fixed at after-poppet (7) and inserts on the core main shaft (not drawing among the figure), can rotate, make the fixed contact (not drawing among the figure) on moving contact and each tap position realize break-make.
