Abstract
The utility model relates to a gas insulated vacuum circuit breaker, which is applicable for gas insulated metal-enclosed switchgear, is characterized in that the circuit breaker has an insulation casing of larger climbing distance, a vacuum interrupter is fixedly arranged in the insulation casing, the operating mechanism uses a structure that a stainless steel bellow is movably connected with the closed part of a gas box; the insulation casing can be a structure of every monomer and can also use a structure of three-phase community. The vacuum interrupter of the inner section of the gas box is fixed using the epoxy resin insulation casing, not only the stable property of the circuit breaker is increased, but the insulation climbing distance is effectively increased, the power frequency withstanding voltage of the circuit breaker can be increased 25kV; the electrical, mechanical service life and the insulation technical targets of the gas-insulated vacuum circuit breaker are effectively improved to ensure that the maintenance-free period of the medium voltage gas-insulated vacuum circuit breaker can be 40 years, and the service life cycle can be 70 years.
Description
Affiliated technical field
The utility model belongs to equipment for power transmission and distribution, especially a kind of vacuum circuit-breaker that is applied to the gas-insulated metal enclosed switchgear of 6～35kV C-GIS equipment for power transmission and distribution.
Background technology
Cubicle Gas-Insulated Switchgear, can abbreviate C-GIS as, with regard to it, the present domestic dependence on import of mainly going back, what imported product was mainly considered on stream is disposable use, the gas tank of one time components and parts all adopts full-closed structure, do not possess the openable function of gas tank, so the mounting means of its breaker vacuum arc control device all adopts the horizontal positioned mode of being convenient to install.Because ground electrical networks such as Europe, North America are the earth neutral system designs, and China's electrical network is an isolated neutral system, the two differs
Insulation voltage doubly, therefore, external its insulation level of vacuum circuit-breaker product also can't reach the requirement of China GB and industry DL standard.In addition, existing C-GIS product is subjected to the totally-enclosed welded process technology limit of gas tank, owing to the horizontal mode that the installation of its gas insulation breaker vacuum extinction unit (vacuum interrupter) is adopted, has influenced the electric and mechanical life-span of vacuum circuit-breaker.
Summary of the invention
In order to overcome the technical problem that exists in the prior art, the utility model proposes a kind of vertically arranged gas-insulated vacuum circuit-breaker of vacuum interrupter that fundamentally solves electric, mechanical endurance and Insulation Problems.
The technical scheme in the invention for solving the technical problem is: the gas-insulated vacuum circuit-breaker, comprise gas tank, vacuum interrupter, the operating mechanism and the electric secondary element that it is characterized in that this circuit breaker are installed on outside the gas tank that is filled with gas, vacuum interrupter is fixed in and has in the insulation drive shell that increases creep distance, and operating mechanism adopts corrugated stainless steel tubing to carry out being dynamically connected of gas tank sealing place; Vacuum interrupter adopts the vertical fixing mode to install in the gas tank that is filled with the specified SF6 of calming the anger gas; Be filled with in the gas tank of the specified SF6 of calming the anger gas, every phase vacuum interrupter is fixedly installed in and has in the insulation drive shell that increases creep distance, and this insulation drive shell can adopt every phase unitary structure, also can adopt three-phase coenosarc formula structure.
The effect that the gas-insulated vacuum circuit-breaker reaches is: the vacuum interrupter in gas tank inside adopts the epoxy resins insulation drive shell to fix, and has not only increased the stability characteristic (quality) of circuit breaker, has also increased the insulation creep distance effectively, can make the circuit breaker industrial frequency withstand voltage improve 25kV; Fundamentally improved electric, the mechanical endurance and the insulation technology index of gas-insulated vacuum circuit-breaker effectively, made its insulation index be higher than IEC standard and external product far away, reached rated short circuit current (31.5kA) and cut-off 50 times; Rated current (2000A) is cut-off 10000 times; Industrial frequency withstand voltage 118kV/1min; The technical indicator of the withstand voltage 218kV of lightning impulse guarantees that the non-maintaining cycle of medium pressure gas insulation vacuum circuit-breaker reaches 40 years, and cycle life-cycle reached more than 70 years;
Description of drawings
Fig. 1 is the structural representation of gas-insulated vacuum circuit-breaker of the present utility model

Gas-insulated Vacuum circuit breaker adopts corrugated stainless steel tubing to carry out being dynamically connected of gas tank sealing place, makes the gas-insulated vacuum circuit breaker The operating mechanism of device is in the gas tank outside, can open cover plate by gas tank, with the vertical peace of vacuum interrupter (2) Be loaded on gas tank inside, live part of air insulation vacuum circuit breaker is in the SF6 gas-insulated state;
The moving contact connecting rod (3) of vacuum interrupter (2) is installed on the gas that is filled with rated pressure SF6 gas In the case, the vacuum interrupter mounting means adopts and is arranged vertically, and vacuum interrupter is every to adopt independent insulation to drive mutually Shell (1) is to the vacuum interrupter isolation of insulating. The branch of air insulation vacuum circuit breaker, making process, head In the operating mechanism action of gas tank outside, logical mechanism's pull bar (6) pulling bellows assembly (7) will be grasped before this The horizontal movement of doing mechanism (9) is sent to the gas tank inside that is filled with SF6 gas, then by mechanism's guide (4) horizontal movement is converted to move both vertically, and then the inner vacuum interrupter (2) of gas tank (10) advances Hang Guan, close action.
Embodiment
Its material of insulation drive shell of gas-insulated vacuum circuit-breaker can select for use insulating material such as epoxy resin to pour into a mould, and its insulation drive shell can adopt three-phase cast form, also can adopt three-phase monomer cast form.Parts such as vacuum interrupter are installed in the gas tank that is filled with rated pressure SF6 gas.The vacuum interrupter of this circuit breaker carries out the vertical fixing formula by the openable passage of gas tank to be installed, and every phase vacuum interrupter is fixed in and has the parts such as the interior vacuum interrupter of insulation drive shell that increase creep distance and be installed in the gas tank that is filled with rated pressure SF6 gas.
