Description
Technical field
This utility model belongs to technical field of electric power, is specifically related to a kind of time delay quick action auxiliary switch.
Background technology
" close point " of primary cut-out refers to after Guan Bi through some milliseconds of times separating brake immediately, and closes between timesharing, i.e. the metal short circuit time is the material time parameter affecting breaking capacity of breaker.Control between involutory timesharing is more difficult, does not has good solution the most so far.One of auxiliary switch highly important element being to ensure that electric power netting safe running.In prior art, auxiliary switch sends according to the Angle Position of rotating shaft and is switched on or switched off signal, for the various operating mechanisms of primary cut-out, controls divide-shut brake loop switch, interlock protection etc..But existing auxiliary switch does not the most have time delay quick action function, the requirement of metal short circuit time cannot be met, so at present, by using auxiliary switch additional delay relay to ensure, it closes between timesharing primary cut-out, this mode is comparatively laborious, and the introducing of time-delay relay simultaneously adds cost of manufacture.
Utility model content
The purpose of this utility model is to provide a kind of time delay quick action auxiliary switch, to solve the problems of the prior art.
nullThis utility model is achieved by the following technical solution: a kind of time delay quick action auxiliary switch，Including shell、Slide block and supply unit，The left surface of described slide block is provided with contact，Described contact is electrically connected with the second contact of supply unit，The inside of described shell is provided with slide plate，One end of described slide plate is fixed with fixing post，The axis of symmetry of described slide plate is provided with Saw blade，Described slide block set is contained on slide plate，Described slide block is engaged with slide plate by plastics ratchet，And slide block is all arranged with two groups of spring fixed columns on fixing post，It is fixed with back-moving spring on described spring fixed column，Described back-moving spring is fixing with slide block and fixing post respectively to be connected，The flank threads of described slide block connects screw rod knob，The end of described screw rod knob is provided with pulley，The side of described slide plate is provided with the chute matched with pulley，Described screw rod knob is connected with slide plate slides.
Preferably, through wires hole is offered inside described slide block upper side.
Preferably, described back-moving spring is arranged with two groups.
Technique effect of the present utility model and advantage: this time delay quick action auxiliary switch, compared with traditional time delay quick action auxiliary switch, this utility model is fixedly connected with a slide block by back-moving spring fixing on spring fixed column, slide block set is contained on slide plate, and slide block engages the second contact delay power of band moving contact and supply unit by plastics ratchet with slide plate, then the pulley of screw rod knob connected by the flank threads of slide block is connected with the slide of the side of slide plate, and controls its speed by the degree of tightness of adjusting screw rod knob and chute；Therefore, its reasonable in design of this utility model, principle is simple and reliable, eliminates the introducing link of time-delay relay, saves cost of manufacture, complies fully with power system and makes primary cut-out have the requirement of " from protection capability " by improving auxiliary switch.
