Abstract
The utility model belongs to the electric shock prevention equipment and especially relates to a compact high-voltage switch cabinet safety protection device. The device comprises a conductive guide rail, an insulating rod and a grounding lead. Three conductive grounding wire clamps which can move on the guide rail are arranged on the guide rail. One end of the grounding lead is connected to any one of the grounding clamps through a fixing screw and the other end is grounded. The grounding clamps are provided with moving contacts. One end of the insulating rod is provided with a connecting device which is cooperated with the moving contacts. A space in the switch cabinet is small so that a grounding wire can not be installed. By using the device of the utility model, the above problem is solved. Manufacturing is simple and installation and dismounting during a usage process are convenient. After the installation, the device does not occupy large space and can be suitable for various kinds of switches.
Description
Technical field
The utility model belongs to protection against electric shock equipment, specifically a kind of compact-type high-pressure switch cubicle safety device.
Background technology
The electrical safe working order regulation: during the high voltage electric equipment maintenance, must be at the both sides installing earth connection that repair apparatus may be sent a telegram here.But in the high voltage electric equipment maintenance process, as a step-down, two step-down GG-1AF type high-tension switch cabinets, because of space in cabinet less, high voltage isolator and circuit breaker spacing are nearer, and earth connection length is 1 meter, because these odjective causes can't be installed earth connection in bus bar side, can only be at one group of earth connection of breaker outgoing line side installing.Like this, maintainer's safety has been formed serious threat, and seriously violated the pertinent regulations of electric industry safety regulations.
Summary of the invention
Technical problem to be solved in the utility model is: how a kind of safety device is provided, prevents that the maintainer is for the moment off one's guard, mistake is touched charging equipment in maintenance process.
The technical scheme that the utility model adopts is: compact-type high-pressure switch cubicle safety device, but comprise conductive guide, insulating bar, earth lead, three conductive earthing clamps that can move on guide rail are arranged on described guide rail, one end of described earth lead is connected to other end ground connection on any described earth clip by fixed screw, have on described earth clip a moving contact is respectively arranged, an end of insulating bar has the jockey that coordinates with moving contact.
As a kind of optimal way: described moving contact termination is double-screw bolt, and described insulating bar is hollow, and there is the screw thread that coordinates with double-screw bolt an end inside of described insulating bar.
The beneficial effects of the utility model are: the utility model has solved switch cubicle internal cause narrow space and can't install the problem of earth connection, the utility model is not only made simply, and fill in use procedure, tear open conveniently, do not take too large place after installation, can be applicable to multiple switch.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the material of earthing clamp is all selected the good copper of electric conductivity, one copper guide rail is installed in three-phase ground wire clamp bottom, the three-phase ground wire clamp can adjust along with circuit breaker three spaced apart, move laterally to suitable position and be connected with the equipment conductor, this invention movable type wire clamp can meet the requirement that the different phase spacings of various circuit breakers use.
Insulating bar is hollow, and material adopts the insulating cement rod, and this material can effectively guarantee operating personnel's personal safety.The termination of insulating bar can be by being rotated in the forward the moving contact that connects earthing clamp.After the three-phase ground wire clamp installs, insulating bar can be pulled down during the insulating bar reverse rotation,, to stay larger space for maintenance to the maintainer, do not hinder staff's activity.
Lower left at earthing clamp is equipped with fixed screw, can be fixed with the line nose of multiply annealed copper wire, guarantees that earthing clamp is connected with the earth reliably by copper conductor.
Select the multiply annealed copper wire of 25mm2 with the multiply annealed copper wire of plastic sheath, to guarantee to meet the requirement of ground connection ampacity.
