Abstract
The invention discloses a switching-on lever for a low-voltage switch. The switching-on lever includes an insulating operating rod. One end of the insulating operating rod is provided with an epoxy switching-on handle, and the other end of the insulating operating rod is provided with an L-type epoxy switching-on lever body. The upper end of the switching-on handle and the upper end of the switching-on lever body are respectively and movably connected with the insulating operating rod through hinge pins. The upper end of the switching-on handle and the upper end of the switching-on lever body are connected through a transmission connecting rod. The switching-on handle and the switching-on lever body are respectively connected with the insulating operating rod through springs. In the switching-on process of the low-voltage switch, the switching-on lever body is aligned with the switching-on handle of the low-voltage switch, an operator holds the tail end of the switching-on handle and pushes forwards the transmission connecting rod, and the switching-on handle of the low-voltage switch is pushed to the switching-on position. As the switching-on handle can rotate, the operator can perform switching-on operation on one side of the switch; in this way, once a short trouble occurs, the operator will not be hurt, and the personal safety of the operator is ensured. Besides, the technical problem of unsafety existing in the prior art is solved.
Description
technical fieldthe invention belongs to electric power combined floodgate utensil technical field, be specifically related to a kind of low tension switch switch lever.
background technologyin low-voltage electrical work, staff is when operation low tension switch, if low-voltage circuit exists fault, the moment that will close a floodgate at low tension switch, short circuit current flows through switch, produce strong arc light and a large amount of heats, easily cause and switch blast electric operation personnel and equipment are damaged, design a kind of safe low tension switch operating grip that closes, safety to electric operation personnel, plays a significant role.
summary of the inventionthe object of the invention is to solve prior art and have unsafe technical problem.Provide a kind of can low tension switch switch lever.
To achieve these goals, low tension switch switch lever of the present invention, it comprises insulating bar; One end of described insulating bar is provided with epoxy resin switch lever, and the other end is provided with L-type epoxy resin combined floodgate bar; The upper end of described switch lever and combined floodgate bar is flexibly connected with insulating bar by bearing pin respectively, and described switch lever is connected by kinematic link with the upper end of combined floodgate bar; Described switch lever is connected with insulating bar by spring respectively with combined floodgate bar.
The present invention is rational in infrastructure, be convenient to make, and when carrying out low tension switch closing operation, by the combined floodgate handle of the accurate low tension switch of combined floodgate pole pair, operating personnel hold switch lever end, and the front kinematic link that pushes away is pushed the combined floodgate handle of low tension switch to closing position.The length of insulating bar, the principle that can ensure personal safety while breaking down according to low tension switch is selected.Meanwhile, switch lever can rotate, and operating personnel can carry out closing operation in the side of switch, once there is low-voltage short-circuiting fault, can not injure operating personnel, guarantees operating personnel's personal safety.The invention solves prior art and have unsafe technical problem.
accompanying drawing explanationaccompanying drawing is that the present invention uses status architecture schematic diagram.
In figure 1, insulating bar 2, switch lever 3, spring 4, kinematic link 5, spring 6, combined floodgate bar 7, low tension switch 8, combined floodgate handle
embodimentwith reference to accompanying drawing, it comprises insulating bar 1 the present invention; One end of described insulating bar 1 is provided with epoxy resin switch lever 2, and the other end is provided with L-type epoxy resin combined floodgate bar 6; The upper end of described switch lever 2 and combined floodgate bar 6 is flexibly connected with insulating bar 1 by bearing pin respectively, and the upper end of described switch lever 2 and combined floodgate bar 6 is connected by kinematic link 4; Described switch lever 2 is connected with insulating bar 1 by spring 3,5 respectively with combined floodgate bar 6.
During combined floodgate, first one end of action bars 1 is fixed on low tension switch 7, combined floodgate bar 6 is aimed to the combined floodgate handle 8 of low tension switch 7; Operating personnel one hold the other end of action bars 1, another holds switch lever 2, to the direction shown in arrow firmly, by kinematic link 4, power is passed to combined floodgate bar 6, and the bar that makes to close a floodgate is to the direction motion shown in arrow, the combined floodgate handle 8 of effect low tension switch, combined floodgate handle 8 is upwards pushed away, low tension switch 7 is closed a floodgate.The effect of spring 3 and spring 5 is mainly for stable operation member.
Before the present invention does not have research and development application: during low-voltage circuit fault, due to the moment that low tension switch closes a floodgate, short circuit current flows through switch, produces strong arc light and a large amount of heats, easily cause switch blast, to electric operation, personnel damage, damage equipment.Nearly 3 years 8-11 months of our work area, (containing load peak, low ebb) < < 0.4kV sky opened maintenance record > >, added up annual drawing sky and outputed existing flash burn person-time 6-8 time every year on average; And after use the present invention: in effect, check and phase 8-11 month flash burn operations staff example does not occur.
Safety benefit of the present invention: safety is the cardinal task of electrical production, the application of the invention, has guaranteed field operation personnel's safety, its benefit cannot be estimated.The low tension switch switch lever of development is used widely within the scope of professional chamber, the principle that can ensure personal safety while breaking down according to low tension switch due to the length of handle is selected, simultaneously, switch lever can rotate, operating personnel can carry out closing operation in the side of switch, and flexible operation, once low-voltage short-circuiting fault occurs, can not injure operating personnel, guarantee operating personnel's personal safety.
