Abstract
The utility model discloses a fuse type knife switch, comprising a bottom board, a crossbeam, guide boards, sockets, fuses, arc-extinguishing chambers, a drive mechanism and an operating mechanism, wherein, three fuses are arranged on the crossbeam side by side, three groups of the sockets and three arc-extinguishing chambers are respectively fixed on the position of the bottom board corresponding to the fuses, the crossbeam can make up and down movement along the guide boards which are fixed on the both sides of the bottom board, the drive mechanism is fixed on the bottom board and connected with the crossbeam, the operating mechanism drives the drive mechanism, and the drive mechanism drives the crossbeam, which realizes the split-closing of the fuses and the sockets. The utility model is characterized in that the operating mechanism adopts a rotary type operating mechanism, and the drive rod of the rotary type operating mechanism is connected with the traction rod of the drive mechanism. The utility model has the advantages of compact structure, convenient installation and convenient operation.
Description
The utility model relates to a kind of switch with fuse that distribution system is made short circuit and overload protection that is used for.
Switch with fuse is made up of base plate, crossbeam, guide plate, transmission mechanism, socket, fuse, arc control device and lever operating mechanism.2 guide plate separation base plate both sides, crossbeam can move up and down along guide plate, 3 fuses are installed on the crossbeam side by side, 3 groups of sockets and 3 arc control device are fixed on the base plate, lever operating mechanism drive transmission device, the fuse that is fixed on the crossbeam is moved up and down along guide plate, insert or pull away socket, to realize the connection and the disjunction of circuit.Use this switch with fuse, when electric wiring is short-circuited or transship, by RTO closed tube fuse with patch seal disjunction fault current, but this switch with fuse adopts the lever operating mechanism, the positive pull switch up and down of operating personnel's palpus, arm need move up and down, and movement range is big, application of force inequality.In addition, the setting height(from bottom) of switch with fuse on power distribution equipment is subjected to the restriction of operating personnel's height, and the component structure that influences power distribution equipment is arranged.
The purpose of this utility model provides a kind of easy to operate, installs to be easy to switch with fuse.
The structure of the switch with fuse that the utility model proposes comprises base plate, crossbeam, guide plate, socket, fuse, arc control device, transmission mechanism and operating mechanism, 3 fuses are installed on the crossbeam side by side, 3 groups of sockets are separately fixed at position corresponding with fuse on the base plate with 3 arc control device, crossbeam can move up and down along the guide plate that is fixed on the base plate both sides, transmission mechanism is fixed on the base plate and with crossbeam and is connected, the operating mechanism drive transmission device, transmission mechanism transmission crossbeam, realize fuse and socket deciliter, it is characterized in that operating mechanism adopts rotary operating mechanism, the drive link of rotary operating mechanism is connected with the draw bar of transmission mechanism.
The switch with fuse compact conformation that the utility model proposes adopts rotary operating mechanism, and fitting operation is convenient.Rotate the handle of operating mechanism, drive link is reciprocating with regard to the draw bar of drive transmission device, realize fuse and socket deciliter.
Followingly concrete enforcement of the present utility model is further described with reference to accompanying drawing.
