Abstract
The invention relates to a high voltage load switch connected by hinged joints. The high voltage load switch comprises a bottom frame, an arc extinguishing chamber, a fuse and a control box, both the arc extinguishing chamber and the fuse are fixed onto the bottom frame through insulators, an isolating switch is arranged on the bottom frame, the inner side of the isolating switch is connected with an insulated pull rod, the insulated pull rod is connected with a spindle at the center of the bottom frame through a rocker, the spindle is connected with the arc extinguishing chamber through a spring transmission mechanism, and joints on the isolating switch and the insulated pull rod are connected by the hinged joints. By the mode, transmission parts are connected by the hinged joints, so that the problem of unbalanced stress is solved, and inharmonious control force is avoided. The service life of the high voltage load switch can be prolonged, abrasion of the high voltage load switch is decreased, and noise in action of the high voltage load switch is reduced.
Description
Technical field
The present invention relates to dynamo-electric manufacturing field, particularly relate to the high voltage load switch that a kind of articulated joint connects.
Background technology
High voltage load switch adopts the principle of vacuum extinction, the beginning ability is strong, and its design volume is little, convenient for installation and maintenance, simple to operate, isolating switch has been opened obviously visible cut-off point, and inlet wire side and load side are arranged apart, can satisfy fully in the situation that the current collection circuit does not have a power failure, change the requirement of fuse or maintenance transformer and low-pressure side.But isolating switch open and close continually can once add the fatigue data of its junction, affects the fatigue strength of its linkage section.And common link is difficult to accomplish stressed uniform effect, so also can affect the useful life of high voltage load switch.
Summary of the invention
The technical problem that the present invention mainly solves is to provide the high voltage load switch that a kind of articulated joint connects, and it is reasonable in design, and is simple in structure, adopts the hinged connected mode of sphere to carry out transmission.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is to provide the high voltage load switch that a kind of articulated joint connects, and comprising: underframe, arc control device, fuse and control cabinet; Described arc control device and fuse all are fixed on underframe by insulator, also are provided with isolating switch on described underframe; Arc control device, fuse and isolating switch are connected copper bus-bar and connect successively, have consisted of the loop of completing; The isolating switch inboard is connected with insulated tension pole, and insulated tension pole is connected with the main shaft at underframe center by rocking bar; Described main shaft is connected with arc control device by spring transmission mechanism; Described isolating switch all adopts articulated joint to be connected with each junction on insulated tension pole.
Preferably, described articulated joint is the articulated joint of spherical structure.
The invention has the beneficial effects as follows: the high voltage load switch that provides a kind of articulated joint to connect, adopt articulated joint connection for transmission spare and driving member, solved so stressed unbalanced problem, avoided the inharmonic phenomenon of control.And be conducive to extend the life-span of product, reduced the wearing and tearing of product, the noise when also having reduced simultaneously the product action.
