Description
Technical field
The present invention relates to a kind of transmission facility technical field, particularly relate to a kind of on-load switch.
Background technology
The operation principle of high voltage load switch is similar to circuit breaker, simple arc-control device is generally housed, but it is relatively simple for structure, figure is a kind of air pressing type high voltage load switch, its course of work is: during separating brake, and under the effect of tripping spring, main shaft turns clockwise, piston is moved up, by gas compression by slider-crank mechanism on the one hand; On the other hand by the drive system of two cover quadric chain compositions, main switch cutter is first opened, and then promote arc extinguishing plug-in strip and arcing contact is opened, the compressed air in cylinder blows out electric arc by spout.During combined floodgate, by main shaft and drive system, main switch cutter and arc extinguishing plug-in strip are turned clockwise simultaneously, and arcing contact first closes; Main shaft is rotated further, and main contact is closed subsequently.In making process, tripping spring is energy storage simultaneously, because on-load switch can not cut-off short circuit current, therefore normal and High Voltage HRC Fuse is used in combination, utilize the current-limiting function of current limiting fuse, not only complete the task of cut-offfing circuit and the heat that can significantly alleviate caused by short circuit current and electrodynamic effect.
Low voltage switch, also known as switch fuse group, is suitable in AC power frequency circuit, has live road with manual infrequently break-make, also can be used for overload and the short-circuit protection of circuit, on-off circuit is completed by contact knife, overload and short-circuit protection are completed by fuse, before 20 century 70s, glue lid knife switch used and enclosed knife switch all belong to low voltage switch, the low voltage switch Contact Breaking/Making Operations speed of low capacity is relevant with lever operated speed, the low voltage switch operating mechanism that capacity is larger adopts spring energy-storage operating principle, sum velocity and lever operated speed speed is divided to have nothing to do, structure is simpler, and with reliable mechanical interlocks, lid open rear switch can not close a floodgate and switch close a floodgate after lid can not open, work safety can be ensured.
Current existing compound switch structure is complicated, safeguards inconvenience, cause useful life shorter after long-time use.
