Abstract
The invention discloses an anti-misoperation demarcating load switch with a disconnecting link. The anti-misoperation demarcating load switch with the disconnecting link comprises a demarcating load switch. A clamping tooth (5) and a locking rod (6) are arranged in the shell (7) of the demarcating load switch; a three-position separation disconnecting link is arranged on the line inlet side of the shell (7) of the demarcating load switch, and comprises a disconnecting link body, a fixed contact (1), a moving contact (2), an grounded fixed contact (10) and a disconnecting link transmission shaft (4). A crank connecting rod (11) is connected to the disconnecting link transmission shaft (4); the crank end of the crank connecting rod (11) is connected to the disconnecting link transmission shaft (4), and the connecting end of the crank connecting rod (11) is hinged in the middle of a main disconnecting link (8); the locking rod (6) is connected to the disconnecting link transmission shaft (4), and rotates along with the disconnecting link transmission shaft (4); the far end of the locking rod (6) makes contact with or is separated from the clamping tooth (5) in the shell of the demarcating load switch. The demarcating load switch is time-saving, labor-saving, safe and convenient to operate.
Description
Technical field
The present invention relates to a kind of demarcation load switch, specifically, is a kind of anti-misoperation demarcation load switch with disconnecting link.
Background technology
Demarcation load switch is a kind of responsibility separation of the 10KV of being installed in overhead distribution, can excise automatically and isolate have single phase ground fault, the circuit of phase fault.Do not possess the isolation switch grounding function in the existing demarcation load switch, after circuit is determined faulty section, during the work of beginning electric power overhaul, usually way is to disconnect on-load switch earlier, after draw back isolating switch, and can begin service work after articulating the working earthing line, because overhead distribution is based on insulated conductor at present, and the user T place of connecing generally also is that insulated conductor or high-tension cable T connect, and is can't hanging earthing conductor not destroying wire insulation, has very big potential safety hazard.For fear of security incident occurring, the power worker adds special ground loop or hanging earthing conductor at T contact line and line, line and cable junction usually, thus so not only time-consuming, effort but also as often processing ease cause that the junction is loosening causes bigger potential safety hazard.
Summary of the invention
The present invention has overcome deficiency of the prior art, and a kind of anti-misoperation demarcation load switch with disconnecting link is provided.
Technical scheme of the present invention is: a kind of anti-misoperation demarcation load switch with disconnecting link, comprise demarcation load switch, in the housing 7 of demarcation load switch, be provided with latch 5 and deadlock lever 6, housing 7 inlet wire sides at described demarcation load switch are provided with three station isolation switchs, described three station isolation switchs comprise disconnecting link, fixed contact 1, moving contact 2, ground connection fixed contact 10, disconnecting link power transmission shaft 4, described fixed contact 1 is connected with inlet wire plate on the demarcation load switch, moving contact 2 is connected with inlet wire plate 3, ground connection fixed contact 10 is connected housing inlet wire side bottom, described disconnecting link is by operator lock 8 and ground connection disconnecting link 9 vertical connecting and composing mutually, be hinged on the moving contact 2 by tie point, operator lock end is positioned at fixed contact 1 side, ground connection disconnecting link end is positioned at ground connection fixed contact 10 sides, the lock 8 of perhaps operating engages with isolation fixed contact 1, perhaps ground connection disconnecting link 9 engages with ground connection fixed contact 10, be connected with crank connecting link 11 at described disconnecting link power transmission shaft 4, the crank end of crank connecting link 11 is connected on the disconnecting link power transmission shaft 4, connecting-rod head is hinged on the middle part of operator lock 8, described deadlock lever 6 is connected on the disconnecting link power transmission shaft 4, rotate the latch 5 in the contact of deadlock lever 6 far-ends or the disengaging demarcation load switch housing with disconnecting link power transmission shaft 4.
Compared with prior art, advantage of the present invention is: when drawing back isolation switch, by interlock, make demarcation load switch excision faulty line, simultaneously ground connection.The present invention has compact conformation, be convenient to install, and simultaneously, switch deciliter ability is strong, and the characteristics that security performance is good can also apply to various on-load switches on the electric pole, above the vacuum switch.
