Abstract
The utility model discloses an electric-shock-resistant door plate of a ring main unit. The electric-shock-resistant door plate comprises a main cabinet and a movable door plate, the back side of the movable door plate is fixedly provided with a screw, the fixed screw is fixed with a copper wire in a contacting and winding manner, and the other end of the copper wire is fixed with a grounding point of the main cabinet in a contacting manner. According to the electric-shock-resistant door plate of the ring main unit, the back side of the movable door plate is fixedly provided with the screw, the fixed screw is fixed with the copper wire in a contacting and winding manner, and the other end of the copper wire is fixed with the grounding point of the main cabinet in a contacting manner so that charge of the movable door plate can be guided to the grounding point of the main cabinet via the copper wire in real time, the electric shock due to the contact of the movable door plate is prevented, and the operation and the usage are safe.
Description
Technical field
The utility model relates to electric equipment, in particular a kind of ring main unit door-plate of protection against electric shock.
Background technology
The Medium Voltage Switchgear of electric system is all from external imported with original packaging the earliest.Main brand has ABB, Siemens and Schneider.Its upper-lower door plate structure is movable withdraw-type, form ground lead with main cabinet metal shell, such defect is that equipment declines for soft cabinet insulating properties, or be subject to external humidification environmental impact, once main cabinet inner high voltage major loop electric leakage, the door-plate of metal material can conduct electricity or store static, and operating personnel are once touch executive component on door-plate and door-plate, can cause Danger Electric shock risk, domestic existing many such accidents occur.
Therefore, there is defect in prior art, needs to improve.
Utility model content
Technical problem to be solved in the utility model is: a kind of ring main unit door-plate that operates and use safe protection against electric shock is provided.
The technical solution of the utility model is as follows: a kind of ring main unit door-plate of protection against electric shock, comprise main cabinet and movable doorboard, also be fixedly installed a screw at the back side of described movable doorboard, on described fixed screw, contact the copper cash that has been fastened, the other end of described copper cash contacts fixing with the earth point of described main cabinet.
Be applied to technique scheme, in described ring main unit door-plate, described screw is M8*20 screw, and described copper cash is 6 squares of annealed copper wires.
Adopt such scheme, the utility model, by being fixedly installed a screw at the back side of movable doorboard, contacts the copper cash that has been fastened on fixed screw, and the other end of copper cash contacts fixing with the earth point of main cabinet; So, the electric charge on movable doorboard can be in real time by the copper cash earth point of main cabinet that leads, get an electric shock thereby prevent from contacting movable doorboard, operation is used safety.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The present embodiment provides a kind of ring main unit door-plate of protection against electric shock, and described ring main unit door-plate arranges protection against electric shock structure, operation and use safety.
Wherein, ring main unit shell generally comprises main cabinet and movable doorboard, main cabinet and movable doorboard all adopt metal material to make, movable doorboard is arranged on master cashier's office in a shop, wherein, can movable doorboard be fixed on to master cashier's office in a shop by hinge, and, can open ring main unit by opening movable doorboard, thereby ring main unit internal components is overhauled.
As shown in Figure 1, also be fixedly installed a screw 103 at the back side of described movable doorboard 101, screw 103 is embedded and is screwed tight the back side that is fixed on movable doorboard 101 by instrument, and, also on fixed screw, contact the copper cash 102 that has been fastened, the exposed part contact of copper cash one end is produced to melt and is fixed on screw, and is screwed in the back side of movable doorboard, contacts fixing with movable doorboard; And the other end of copper cash 102 contacts fixing with the earth point of described main cabinet, for example, also can the exposed part of the other end of copper cash be fixed on earth point by screw, or, be directly fastened on the earth point of main cabinet; So, the electric charge on movable doorboard can be in real time by the copper cash earth point of main cabinet that leads, get an electric shock thereby prevent from contacting movable doorboard, operation is used safety.
Wherein, it is M8*20 screw that screw 103 can adopt gauge size, and copper cash preferentially adopts 6 squares of annealed copper wires, and so, copper cash can bear abundant electric charge, and, adopt annealed copper wire, facilitate the installation of copper cash fix and connect up.
These are only preferred embodiment of the present utility model, be not limited to the utility model, all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
Claims (2)
1. a ring main unit door-plate for protection against electric shock, comprises main cabinet and movable doorboard, it is characterized in that:
Also be fixedly installed a screw at the back side of described movable doorboard, contact the copper cash that has been fastened on described fixed screw, the other end of described copper cash contacts fixing with the earth point of described main cabinet.
2. ring main unit door-plate according to claim 1, is characterized in that, described screw is M8*20 screw, and described copper cash is 6 squares of annealed copper wires.
