Abstract
The utility model relates to an outdoor high-voltage alternating current vacuum breaker. A wire inlet end of the breaker is electrically connected with a wire inlet base; a wire outlet end of the breaker is educed from an upper contact base through a fixing seal pole pillar; an isolating cutter comprises a first tail end and a second tail end; the first tail end is hinged with the upper contact base; the second tail end is moveably hinged with one end of an insulating pull rod; the other end of the insulating pull rod is fixedly connected with an insulating pillar; the second tail end is in contacting connection with a wire outlet base; the outdoor high-voltage alternating current vacuum breaker comprises an energy storage handle and a manual switching handle; the manual switching handle acts on the second tail end through the insulating pillar and the insulating pull rod; and the energy storage handle acts on an energy-storing spring in a spring operation mechanism. The isolating cutter and the insulating pull rod are folded or stretched by operating the manual switching handle, so that the second tail end on the isolating cutter is in contact with or separated from the wire outlet base and the switch-on/off of an isolating switch is realized. The outdoor high-voltage alternating current vacuum breaker has the characteristics of simple structure, convenience in operation, easiness in mounting, and safety and reliability in use.
Description
Technical field
The utility model relates to a kind of outdoor high-voltage alternating current vacuum circuit-breaker.
Background technology
High-pressure vacuum breaker be applicable to rated voltage 3KV and more than, be used for connecting electrical equipment with the disjunction galvanic circle.It mainly is made up of vacuum interrupter, electromagnetism or spring operating mechanism, support and other parts.The break-make electricity of high-pressure vacuum breaker mainly is the moving contact in the dependence vacuum interrupter and realizes effective connection of fixed contact.Because the spacing in the vacuum interrupter between moving contact and the fixed contact is less, if the vacuum extinction decreased performance very likely can cause short circuit because of air breakdown.Therefore high-pressure vacuum breaker generally cooperates isolating switch to use, and purpose is in the galvanic circle, to increase isolation fracture, makes the disjunction of galvanic circle safer.The combined electrical apparatus complex structure of existing high-pressure vacuum breaker and isolating switch, bulky very likely misoperation occurs during use and causes security incident, and in addition, product is installed also relatively difficulty.
Summary of the invention
The purpose of the utility model is to overcome the defective of prior art, provide a kind of simple in structure, when operation is safe and reliable and be convenient to the outdoor high-voltage alternating current vacuum circuit-breaker that equipment is installed.
For realizing above-mentioned purpose; The utility model adopts a kind of like this outdoor high-voltage alternating current vacuum circuit-breaker, comprises circuit breaker and isolation knife, and said circuit breaker is arranged in casing; The end of incoming cables of described circuit breaker is electrically connected to the inlet wire seat; The leading-out terminal of described circuit breaker is drawn touch base through pole, and described isolation knife comprises first terminal and second end, and described first end is articulated in the described touch base of going up; Described second end is movably hinged the end in insulated tension pole; The other end of described insulated tension pole is fixedly connected insulation column, and described second terminal the touching with the outlet seated connection is connected, and described outdoor high-voltage alternating current vacuum circuit-breaker comprises energy storage handle and manual divide-shut brake handle; Described manual divide-shut brake handle acts on described second end through described insulation column, described insulated tension pole, and described energy storage handle acts on the energy-stored spring in the spring operating mechanism.
Especially, described outdoor high-voltage alternating current vacuum circuit-breaker comprises the mechanical interlocking structure, and described mechanical interlocking structure acts on described circuit breaker and rotating shaft respectively, and described rotating shaft and described manual divide-shut brake handle keep interlock.
Compared with present technology; The beneficial effect of the utility model is embodied in: through operating manual divide-shut brake handle; Make isolation knife and insulated tension pole amount to or stretch, thereby make the terminal contact of second on the isolation knife or leave the outlet seat, realize the closure and the disjunction of isolating switch.In addition,, the operation of circuit breaker and isolating switch is carried out in certain sequence, stopped the misoperation behavior through the mechanical interlocking structure.The utlity model has simple in structure, easy to operate, be easy to install and safe and reliable characteristics.
