Abstract
The utility model discloses an anti-misoperation locking rod which mainly consists of a locking rod and a buckle device which is connected with the lower end of the locking rod, the upper end of the locking rod is provided with a hook. The buckle device is connected with the locking rod by a lock catch and the buckle device is of anchor ear structure or watch chain structure. The locking rod consists of at least one rod body, and the rod bodies are connected by connecting joints so as to control the length of the locking rod. The lower end of the locking rod is provided with a rain cover. The locking rod is made of insulating-material epoxy resin. By applying a down force to an electric rod load knife, the anti-misoperation locking rod locks the load knife and ensures the load knife always in the breaking state, thus avoiding human injury caused by charged line owning to closed load knife caused by misoperation or uncertain factors.
Description
Technical field
The utility model safeties, particularly a kind of electrical network high voltage power anti-incorrect manipulation deadlock lever of working line electric pole.
Background technology
Guarantee in " State Grid Corporation of China's electric power safety working regulation " power circuit part that technical safety measures when power circuit work personnel work has power failure, electrical verification, installing earth connection, uses individual security personnel's line, hangs indication plate and installing is blocked on the interruption maintenance circuit.
Because of causing unexpected combined floodgate of power failure equipments, the external force factor influence make the dead line accident charged for preventing simultaneously, clearly stipulate once more among " State Grid Corporation of China's electric power safety working regulation " power circuit part 3.2.2: each end in power failure equipments should have obvious cut-off point (except the equipment that can't observe obvious cut-off point).Should lock on the operating mechanism of circuit breaker (switch), isolating switch (disconnecting link); The fusion tube of fuse switch should be taken.
Along with the application of modern technologies, adopted the load plug-in strip in a large number at operation of power networks circuit 1# lever switch device at present, this be a kind of arc extinguishing function and obvious cut-off point of collecting for all over the body, with the switchgear of quick operating mechanism, easy to operate.But can't realize pinning function after plug-in strip draws back, be subjected at equipment under the situation of external force, machinery or other factors, may cause malfunction to close a floodgate, make interruption maintenance equipment charged, cause the line maintenance personnel injury of getting an electric shock.
Summary of the invention
The purpose of this utility model is to provide a kind of electric pole plug-in strip that can pin for the deficiency that solves above-mentioned technology, and is easy to operate, and safe and reliable high voltage power anti-incorrect manipulation deadlock lever.
In order to achieve the above object, the novel designed high voltage power anti-incorrect manipulation deadlock lever of this usefulness, it mainly is made up of deadlock lever and clasp, and clasp is connected the deadlock lever lower end, and the deadlock lever upper end is provided with hook.In order to guarantee effective connection very, clasp is connected with deadlock lever by snap close, and clasp can be hood type structure or table chain structure, to adapt to the needs of various different environments for use.Deadlock lever is made up of a pole body at least, connects by being connected joint between the body of rod and the body of rod, can increase or reduce the quantity of the body of rod accordingly to the electric pole of differing heights, to control the length of deadlock lever.Bottom at deadlock lever is provided with rain cover, can not form path because of natural causes such as rainwater with the protection operating position.Deadlock lever is to be made of insulating material epoxy resin, has guaranteed the fail safe of operation.
The resulting high voltage power anti-incorrect manipulation deadlock lever of the utility model, by being continuously applied a downward active force to electric pole load plug-in strip, locking load plug-in strip, make the load plug-in strip remain at the state of cut-offfing, effectively avoided causing the charged personnel's injury that causes of circuit because of the load plug-in strip closure that misoperation or some uncertain factors cause.This high voltage power anti-incorrect manipulation deadlock lever simultaneously also has simple in structurely, easy to operate, safe and reliable, very easily quantizes characteristics such as production.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
In conjunction with the accompanying drawings patent of the present invention is further described below by embodiment.
Embodiment 1
As shown in Figure 1, the high voltage power anti-incorrect manipulation deadlock lever that present embodiment is described, it mainly is made up of deadlock lever 1 and clasp 2, and clasp 2 is connected deadlock lever 1 lower end, and deadlock lever 1 upper end is provided with hook 3.In order to guarantee effective connection very, clasp 2 is connected with deadlock lever 1 by snap close 4, and clasp 2 is table chain structures.Deadlock lever 1 is made up of three pair rod body 7, connects by being connected joint 5 between the body of rod 7 and the body of rod 7, is provided with rain cover 6 in the bottom of deadlock lever 1, can not form path because of natural causes such as rainwater with the protection operating position.Deadlock lever 1 is made up of insulating material epoxy resin, has guaranteed the fail safe of operation.
During use, high voltage power anti-incorrect manipulation deadlock lever hung on the handle hole of load plug-in strip operating sheet 8, pull down to extreme position by deadlock lever 1 plug-in strip 8 of will loading by linking up with 3.By clasp 2 deadlock lever 1 lower end is fixed on the electric pole 9 then, the extreme position that makes load plug-in strip 8 remain at disconnection gets final product.
