Abstract
The invention relates to an outdoor high-voltage switchgear used in a power system, and discloses a compact handcart type sealed insulating pole horizontal permanent magnetic vacuum breaker. The breaker comprises a handcart, wherein the handcart is provided with an operating box; an operating mechanism is arranged in the operating box; the operating box is provided with three sealed insulating poles which are connected with the operating mechanism; the breaker is characterized in that the three sealed insulating poles are horizontally arranged on the side wall of the operating box side by side; front movable contacts in the sealed insulating poles and the insulating poles are coaxially arranged and sealed by an insulating coating; the middle parts of the insulating poles are provided with a reverse L-shaped insulating arm; a rear movable contact and a conducting plate are sealed in the insulating arm; and the two ends of the conducting plate are connected with the rear movable contact and a movable contact of a vacuum arc extinguishing chamber respectively. The breaker solves the problems of large size, high cost, poor insulating property and the like of the conventional similar breaker, and is particularly suitable for opening or closing load current, overload current and short-circuit current in the power system.
Description
The ㈠ technical field: the outdoor high-voltage shape equipment that the present invention relates to use in the electric power system, especially a kind of compact handcart-type seal the horizontally-arranged permanent magnetism vacuum circuit-breaker of insulation pole admittedly.
㈡ background technology: at present, the switch that uses in the electric power system both at home and abroad is various in style, most typical have a loop-network switch cabinet, handcart type vacuum circuit breaker is a critical piece that is used for loop-network switch cabinet, existing handcart type vacuum circuit breaker, it comprises handcart, actuating case and operating mechanism are installed on the handcart, in the setting of the top of actuating case three solid envelope insulation poles are installed, each solid envelope insulation pole includes insulation column and former and later two moving contacts, is provided with vacuum interrupter in insulation column inside, and the insulated tension pole assembly is housed, wherein former and later two moving contacts are to be arranged vertically with insulation column, and only are set with silicone rubber sleeve in the outside of two moving contacts.Because the insulation property of silicone rubber sleeve are relatively poor, and there is the gap between silicone rubber sleeve and the insulation column, the main air insulation that relies between front and back moving contact between adjacent like this two solid envelope insulation poles and former and later two moving contacts in the same pole, therefore enough big between the pole in twos apart from requiring, enough big between the front and back moving contact in the same pole apart from also requiring; Make that the existing circuit breaker volume is big, materials are many, the cost height, and insulation property are poor, can not adapt to various adverse circumstances and use.Erectting the solid envelope insulation pole of installing on the other hand takes up room bigger in ring main unit.
The ㈢ summary of the invention: purpose of the present invention will solve exactly that existing handcart type vacuum circuit breaker volume is big, cost is high, insulation property are poor, can not adapt to adverse circumstances and use and the big problem that takes up room, provide a kind of compact handcart-type to seal the horizontally-arranged permanent magnetism vacuum circuit-breaker of insulation pole admittedly.
Concrete scheme of the present invention is: improve at existing handcart type vacuum circuit breaker, it includes handcart, the actuating case is installed on the handcart, in the actuating case operating mechanism is installed, on the actuating case, be connected three solid envelope insulation poles are housed with operating mechanism, each solid envelope insulation pole includes insulation column, with former and later two moving contacts, be provided with vacuum interrupter in insulation column inside, and the insulated tension pole assembly is housed, this insulated tension pole assembly links to each other the permanent-magnet manipulating mechanism of circuit breaker with the moving contact of vacuum interrupter, the fixed contact conducting of moving contact and vacuum interrupter before described, the moving contact conducting of back moving contact and vacuum interrupter is characterized in that: described three solid envelope insulation poles be and the horizontal sidewall that is installed in the actuating case of row of horizontal on; Moving contact is and the insulation column coaxial arrangement before in the described solid envelope insulation pole, the major part of preceding moving contact is sealed with insulating coating, insulating coating is and the insulation column structure that pours into an integrated entity, and " 7 " font insulation arm is arranged in the design of the middle part of insulation column, this insulation arm is to pour into an integrated entity with insulation column, horizontal segment at insulation arm is sealed with the back moving contact, and the vertical section of insulation arm is sealed with conduction panel, and the conduction panel two ends connect the moving contact of back moving contact and vacuum interrupter respectively.
Back moving contact axis and preceding moving contact parallel axes are arranged described in the present invention, two contact pitch≤200mm.
Insulation column described in the present invention and insulation arm and insulating coating are to adopt the high-performance epoxy resin material to pour into an integrated entity.
The width of handcart described in the present invention is controlled in the 300-400mm.
The operating mechanism of installing in the case of actuating described in the present invention is to adopt permanent-magnet manipulating mechanism.
The present invention has been owing to changed two moving contact structure positions, and taked solid envelope insulation measures in its outside, adopts high-performance epoxy resin to insulate, and the space length between each moving contact is reduced greatly; Introduced permanent-magnet manipulating mechanism simultaneously; Characteristics such as make that circuit breaker of the present invention has that compact conformation, volume are little, in light weight, low cost of manufacture, precision height, reaction speed are fast, high reliability, life-span are long, non-maintaining.And solid envelope insulation pole is taked horizontal type structure among the present invention, and the length that makes pole is to consistent with the handcart direction of motion, and highly reduction, so the present invention is used for loop-network switch cabinet, and to take volume little.
