Abstract
The invention discloses a double contact of a vacuum arc extinguishing chamber. The double contact is characterized by being provided with two contact bodies of the same structures, wherein each contact body mainly comprises a main contact base, a contact limiting block, a guide cylinder, a pressure spring, an auxiliary contact base, a main contact and an auxiliary contact; and respective main contacts and auxiliary contacts of the two contact bodies of the same structures are opposite to each other, and can be absorbed to be contacted or separated. In the switch-on/off process of the contacts of the vacuum arc extinguishing chamber, the main contact is not eroded and abraded, the contact resistance between the contacts is low, and the resistance value is less than 2 micro-ohm, so that the resistance of a main loop of a circuit breaker can be reduced, the heating amount of the main loop of the circuit breaker is lowered, the application performance of the vacuum circuit breaker is enhanced, and the service life of the vacuum circuit breaker is prolonged.
Description
Technical field
The invention belongs to the electrical engineering technical field, particularly relate to the improvement of vacuum arc-extinguishing chamber contact.
Background technology
The break-make of vacuum circuit-breaker is closed by vacuum arc-extinguishing chamber contact and is closed, cut-offs realization in the power circuit.Present vacuum interrupter product on the market, its design and manufacturing process thereof be comparative maturity, but goes back existent defect.During normal operation circuit, vacuum arc-extinguishing chamber contact flows through load current, vacuum arc-extinguishing chamber contact cut-offs fault or load current when fault or stoppage in transit, along with increasing of vacuum arc-extinguishing chamber contact open and close times, and serious, contact Contact resistance increase that contact is ablated, weares and teares, worn out.Circuit breaker major loop caloric value increases, and vacuum arc extinguish chamber housing epoxy resin heat dispersion is relatively poor, and the high heat of generation has a strong impact on serviceability and the useful life of vacuum circuit-breaker and parts thereof.For the problem of present vacuum arc-extinguishing chamber contact existence and the negative effect that brings thereof, the development of new vacuum arc-extinguishing chamber contact is very important.
Summary of the invention
The objective of the invention is to manufacture and design the two contacts of a kind of vacuum interrupter, to overcome present vacuum interrupter product, contact flows through load current, vacuum arc-extinguishing chamber contact cut-offs fault or load current when fault or stoppage in transit, along with increasing of vacuum arc-extinguishing chamber contact open and close times, serious, contact Contact resistance increase that contact is ablated, weares and teares, worn out.Circuit breaker major loop caloric value increases, and vacuum arc extinguish chamber housing epoxy resin heat dispersion is relatively poor, and the high heat of generation has a strong impact on the serviceability of vacuum circuit-breaker and parts thereof and the shortcoming in useful life.
The objective of the invention is to reach like this: the two contacts of vacuum interrupter, it is characterized by: have two contact bodies that structure is identical, described contact body comprises that mainly an end is fixed with the main contact seat 4 of main contact 6, be arranged in the main contact seat 4 and the contact guide vane end stop 1 that links to each other with guide cylinder 2, be arranged in the main contact seat 4 and guide cylinder 2 that two ends link to each other with stage clip 3 with contact guide vane end stop 1 respectively, be arranged in the main contact seat 4 and stage clip 3 that two ends link to each other with main contact seat 4 with guide cylinder 2 respectively, be arranged at the auxiliary contact base 5 that main contact seat 4 interior also ends are fixed with auxiliary contact 7, be fixed in the main contact 6 of main contact seat 4, be fixed in the auxiliary contact 7 of auxiliary contact base 5, the identical contact body of described two structures, but main contact 6 separately and auxiliary contact 7 are in twos in opposite directions and adhesive or separate.
When the two contacts of vacuum interrupter normally move, main contact conducting load current; When vacuum arc-extinguishing chamber contact cut-offs, the disjunction of main contact elder generation, auxiliary contact drop-out current; Vacuum arc-extinguishing chamber contact closes when closing, and auxiliary contact closes first, closes behind the main contact.
Main contact 6 adopts silver oxide to make.
Auxiliary contact 7 adopts chromiumcopper to make, and copper weight of chromium ratio respectively accounts for 50 percent.
Take the present invention of above measure, close at vacuum arc-extinguishing chamber contact close, in the interrupting process, contact is not ablated, wearing and tearing, contact Contact resistance is little, its resistance is less than 2 micro-ohms, can reduce circuit breaker major loop resistance, reduce the caloric value of circuit breaker major loop, improve serviceability and the useful life of vacuum circuit-breaker.
Below the invention will be further described by reference to the accompanying drawings again.
Description of drawings
Accompanying drawing 1 is the structural profile schematic diagram of the present invention's (embodiment) a contact body.
Description of reference numerals: contact guide vane end stop 1, guide cylinder 2, stage clip 3, main contact seat 4, auxiliary contact base 5, main contact 6, auxiliary contact 7.
Embodiment
Accompanying drawing 1 has provided the structural profile schematic diagram of a contact body of the embodiment of the invention.Can know the structure that the present invention is inner concrete referring to accompanying drawing 1.
The contact body comprises that mainly an end is fixed with the main contact seat 4 of main contact 6, be arranged in the main contact seat 4 and the contact guide vane end stop 1 that links to each other with guide cylinder 2, be arranged in the main contact seat 4 and guide cylinder 2 that two ends link to each other with stage clip 3 with guide vane end stop 1 respectively, be arranged in the main contact seat 4 and stage clip 3 that two ends link to each other with main contact seat 4 with guide cylinder 2 respectively, be arranged at the auxiliary contact base 5 that main contact seat 4 interior also ends are fixed with auxiliary contact 7, be fixed in the main contact 6 of main contact seat 4, be fixed in the auxiliary contact 7 of auxiliary contact base 5.The contact body is except main contact 6 and auxiliary contact 7 usefulness metal materials are made, and miscellaneous part is made with insulating material.Main contact 6 and auxiliary contact 7 are done circlewise.
The present invention has two contact bodies that structure is identical.Two contact bodies that structure is identical, but main contact 6 separately and auxiliary contact 7 are in twos in opposite directions and adhesive or separate.One of them contact body can be fixed as the fixed contact body, and another contact body is that the moving contact body moves under the effect of external force, and main contact 6 separately and auxiliary contact 7 are in twos in opposite directions and adhesive or separate.
