Description
Technical field
This utility model relates to a kind of interlock, particularly relates to the interlock of a kind of on-load switch.
Background technology
On-load switch is generally equipped with simple arc-control device, but it is relatively simple for structure, and its work process is: during separating brake,
Under the effect of tripping spring, main shaft turns clockwise, and on the one hand makes piston move up by slider-crank mechanism, by gas
Compression；On the other hand by the drive system of two set quadric chain compositions, make main switch cutter first open, then promote arc extinguishing plug-in strip
Making arcing contact open, the compressed air in cylinder blows out electric arc by spout.

The drive system of linkage composition, makes main switch cutter first open, and then promotes arc extinguishing plug-in strip to make arcing contact open, the pressure in cylinder
Contracting air blows out electric arc by spout.During combined floodgate, by main shaft and drive system, make main switch cutter and arc extinguishing plug-in strip the most clockwise
Rotating, arcing contact first closes；Main shaft is rotated further, and makes main contact close subsequently.In making process, tripping spring is store simultaneously
Energy.Owing to on-load switch can not cut-off short circuit current, therefore often it is used in combination with High Voltage HRC Fuse, utilizes current limliting
The current-limiting function of fuse, is not only completed and cut-offs the task of circuit and can significantly alleviate the heat caused by short circuit current and electronic
The effect of power.
The high pressure dry hole formula limiting fuse of existing combined transformer is the most upper and lower with high voltage load switch to be arranged on
On fuel tank, when on-load switch is in fuse band electric position, blocking owing to fuse operation handle lacks, careless slightly meeting is drawn
Play the generation of maloperation event, be i.e. under electriferous state operation at high pressure dry hole formula limiting fuse, thus cause personnel to hinder
Dying and device damage accident, therefore needing that research and development one avoids badly can be to fusing when on-load switch is in and makes fuse band electric position
Device operates, thus effectively prevent the interlock of the on-load switch of casualties and the generation of device damage accident.
