Abstract
A tank type high-pressure vacuum circuit breaker solves the problems that a structure integrally and solidly sealing a silicon rubber insulator with an arc extinguish chamber is complex in manufacturing process and incapable of allowing the arc extinguish chamber to be replaced independently, and the vacuum arc extinguish chamber directly mounted in high-pressure insulating gas bears high pressure. The tank type high-pressure vacuum circuit breaker is characterized in that a cavity between a vacuum arc extinguish chamber and a large insulating cylinder and a cavity between a small insulating cylinder and an operational insulating rod are communicated with each other to form a closed low-pressure gas compartment filled with 0-0.1MPa dried air or nitrogen, and a cavity between the large insulating cylinder and a tank and a cavity between the small insulating cylinder and the tank form a closed high-pressure gas compartment filled with 0.15-0.6MPa dried air or nitrogen. The tank type high-pressure vacuum circuit breaker has the advantages that the vacuum arc extinguish chamber is operated in the low-pressure gas compartment so as to be protected effectively, and the high-pressure gas compartment guarantees insulating performance of the circuit breaker, so that only the vacuum arc extinguish chamber needs to be replaced singly if the vacuum arc extinguish chamber fails.
Description
Technical field
The invention belongs to high voltage electrical apparatus technical field, particularly high-voltage system is with a kind of pot type high-pressure vacuum breaker of dry air or nitrogen insulation.
Background technology
Existing primary cut-out product adopts sulphur hexafluoride to cut-off medium as electric insulation and circuit more, and a large amount of uses of sulphur hexafluoride can produce pollution to environment.For these reasons, adopt the circuit that cut-offs of the vacuum technology of cut-offfing to obtain enforcement in the high voltage field gradually.In the prior art, be the disclosed a kind of outdoor high-voltage vacuum breaker of 03133431.8 patent application like application number, it does not use sulfur hexafluoride gas to do insulation gas; But the technical scheme that it is taked is to charge into a kind of fluid silicone rubber dielectric in the arc control device outside, and the cooling back forms solid-state silicon rubber insulation body; This silicon rubber insulation body is enclosed in arc control device admittedly; Complex manufacturing technology especially when arc control device break down, can't be changed arc control device separately.And for example; A kind of high-pressure vacuum breaker that Nippon AE Pava Co., Ltd. produces, it does not use sulfur hexafluoride gas to do insulation gas yet, still; The technical scheme that it is taked is that vacuum interrupter is directly installed in the insulating gas of high pressure; Vacuum interrupter directly is in the high-pressure gas, so the vacuum interrupter pressure-bearing is very high, has so just increased the manufacture difficulty of vacuum interrupter.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the weak point of prior art, and a kind of pot type high-pressure vacuum breaker with dry air or nitrogen insulation is provided.
The technical solution that the present invention adopted comprises vacuum interrupter, tank body and pressure relief device; At the outdoor big insulating cylinder made from epoxy resin that is equipped with of vacuum extinction; Said big insulating cylinder right ends is separately installed with left bucking electrode and right bucking electrode; The left end of left side bucking electrode is installed little insulating cylinder; Cavity between vacuum interrupter and the big insulating cylinder and little insulating cylinder are connected with cavity between the operation insulating bar and form the low-pressure gas compartment that seals; Outside big insulating cylinder and little insulating cylinder, tank body is installed, the cavity between big insulating cylinder and little insulating cylinder and the tank body forms the gases at high pressure compartment of sealing, is connected with left connection bus and right connection bus respectively at left bucking electrode and right bucking electrode outer upper end.
Said left bucking electrode and right bucking electrode are rotational symmetry structure.
In the low-pressure gas compartment, charge into dry air or the nitrogen of 0～0.1MPa (gauge pressure), in the gases at high pressure compartment, charge into 0.15～0.6MPa (gauge pressure) dry air or nitrogen.
During use; Said vacuum interrupter is the three-phase absolute construction, and every phase all is installed in the low-pressure gas compartment, this low-pressure gas compartment is packed in the tank body again; Tank body is rack-mount; One side attended operation mechanism, the top of every phase arc control device is connected the top leading-out wire sleeve pipe of each current transformer through connection bus with the pair of electrical current transformer.
Compared with prior art, the invention has the beneficial effects as follows:
(1) the present invention is installed in vacuum interrupter and operation insulating bar in the low pressure gas compartment of sealing; Vacuum interrupter is operated in the gas of dry air or the such low-pressure of nitrogen of 0～0.1MPa (gauge pressure); Thereby vacuum interrupter and bellows have been protected effectively; And the 0.15～0.6MPa that charges in the high-pressure gas compartment (gauge pressure) dry air or nitrogen hyperbar have guaranteed the insulation property of circuit breaker; So just need not re-use sulfur hexafluoride gas does insulation gas, has also reduced the manufacture difficulty of vacuum interrupter simultaneously, if vacuum interrupter breaks down; Only need to change separately vacuum interrupter and get final product, whole high-pressure vacuum breaker then can normally use.
(2) the present invention's left side bucking electrode and right bucking electrode are rotational symmetry structure, can play the effect of uniform electric field and heat radiation.
