Description
Technical field
The utility model relates to a kind of electric switch, particularly a kind of isolating switch with ice-melt short circuit and ground connection handoff functionality.
Background technology
When transmission line being carried out to the ice-melt operation, the transmission line end need to be carried out to the three-phase shortcircuit connection, after completing, ice-melt work also needs to remove this connection.In existing mode of operation, aforesaid operations is by manually carrying out this work (according to on-the-spot practical experience, the time that completes 110kV and following transmission line short circuit and remove the short circuit operation was generally about 0.5-1 hour), existing mode causes the security risk of ice-melt inefficiency, maintainer's field operation high.The applicant has designed a set of technical scheme in order to address this problem before this, this scheme application utility model patent, and obtained mandate, its name is called " with the isolating switch of ice-melt short-circuit function " (patent No.: ZL201220115423.4).But, adopt this scheme to complete this work, need to increase additional space, versatility is restricted; " with the isolating switch of ice-melt short-circuit function " manufacturing cost is relatively high in addition.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of isolating switch with ice-melt short circuit and ground connection handoff functionality is provided, it realizes the quick switching of ice-melt short circuit and conventional grounding function, the three-phase shortcircuit that completes the transmission line end connects, do not need to change outward appearance main structure and the basic installation dimension of prototype isolating switch simultaneously, do not need to increase additional space, to overcome the deficiencies in the prior art yet.
The utility model is achieved in that the isolating switch with ice-melt short circuit and ground connection handoff functionality, comprise vertical support frame, be provided with operating mechanism I and operating mechanism II on vertical support frame, be connected with vertical links on the operating mechanism I, top at vertical support frame is provided with horizontal stand, be provided with insulating carriage on horizontal stand, be provided with horizontal conductive link on insulating carriage, be provided with junction block on horizontal conductive link, junction block is arranged with the one pole grounding switch and is connected by aluminium, the earth terminal of one pole grounding switch is arranged with horizontal stand and is connected by aluminium, the bottom of one pole grounding switch is connected with the top of vertical links, be provided with post insulator on horizontal stand, at the top of post insulator, be provided with the isolated switch main disconnecting link contact, on the isolated switch main disconnecting link contact, be provided with fixed contact pedestal, the vertical conduction bar presss from both sides and is fixed on horizontal conductive link by conductive connecting, and horizontal conducting rod is connected with the operating mechanism II by the insulation level connecting rod.
Insulating carriage plays the effect that horizontal conductive link and horizontal stand are isolated mutually, has met the requirements of insulation level.
Operating mechanism I and operating mechanism II are the electric linkage structure of three-phase.1 of the every phase of motor-operating mechanism, realize the phase-splitting operation, electric-linked operation between three-phase.
The operating mechanism I can be man-operating mechanism or motor drive mechanism, when the operating mechanism I drives the vertical links rotation, drive one of them insulator rotating of one pole grounding switch simultaneously, connecting rod interaction through between one pole grounding switch pole, make two insulators rotations, thus realize the one pole grounding switch minute, closing operation.
In the present invention, formed " short circuit and ground connection " disconnecting link by horizontal conducting rod, vertical conduction bar and insulation level connecting rod, the operating mechanism II can be man-operating mechanism or motor drive mechanism, the operating mechanism II be " short circuit and ground connection " disconnecting link realize motion and complete minute, the power resources of closing operation: when the operating mechanism II drives vertical links and rotates, drive the level insulation link motion simultaneously, like this, the horizontal conducting rod be attached thereto is rotation simultaneously also, by rotarily driving the vertical conduction bar motion of three-phase, thus realize " short circuit and ground connection " disconnecting link minute, closing operation.
The utility model realizes that the switching concrete steps of " short circuit and ground connection " functional mode are:
Short-circuit function: the first step: pull open one pole grounding switch (by being incorporated into minute); Second step: " short circuit and ground connection " disconnecting link (closing by assigning to) closes.Grounding function: the first step: the one pole grounding switch that closes (closing by assigning to); Second step: " short circuit and ground connection " disconnecting link (closing by assigning to) closes.
Owing to having adopted above-mentioned technical scheme, compared with prior art, the utility model utilizes existing isolating switch to be improved, make the structure with ice-melt short circuit and ground connection handoff functionality isolating switch, only need by operating the one pole grounding switch to closing position, just can be according to normally operation under the normal mode of original isolating switch; When needs carry out short circuit by circuit, only need pull open original isolating switch, then pull open the one pole grounding switch, the three-phase shortcircuit that " short circuit and the ground connection " disconnecting link that closes again can complete transmission line is connected, complete operation only needed about 1-2 minute, and eliminated maintainer's job safety risk fully.The utility model is simple in structure, economic and practical, and does not need to increase additional space, and result of use is good.
