Abstract
The utility model discloses a conveniently detachable type end screen grounding device comprising an end screen screw rod connected with a capacitive type device. The screw rod is provided with a nut. One end of the screw rod is in the shape of a cuboid, and an outer side of the screw is provided with a housing. A grounding end of the screw rod of the end screen grounding device is in the shape of a cuboid, therefore a grounding end screw of the end screen grounding device can be conveniently assembled and detached, and the loosening phenomenon of the screw rod and the nut of the end screen grounding device during the reassembly can be prevented, and the safety hidden troubles can be eliminated. The outer side of the screw rod is provided with the housing, the erosion of the screw rod caused by rain, snow and moisture can be prevented, and the corrosion locking between the screw rod and the nut can be prevented. The conveniently detachable type end screen grounding device has advantages of simple economic practical structure, easy realization, no extra costs, and abilities of maintaining normal operation of electric devices, and reducing losses of electric power company.
Description
Technical field
The utility model belongs to the power construction equipment technical field, particularly a kind of detachable end screen earthing device.
Background technology
Screen necessary good earth in capacitive electric equipment in the electric power system (transformer high-voltage sleeve pipe, capacitive current transformer, capacitor type wall bushing, capacitance type potential transformer, coupling capacitor etc.) end produces otherwise have high voltage.For this reason, electric equipment manufacturer has all adopted multi-form end screen earthing device, to guarantee reliable ground, prevents high-tension generation.At present, produce the producer of capacitive electric equipment, all adopted the full screw thread screw rod to be equipped with end screen and earthing conductor that nut connects capacitance type equipment, reach the purpose of reliable ground.
Capacitive electric equipment is in outdoor mostly, usually is subjected to the erosion of sleet, humidity, makes to occur the corrosion locking phenomenon between screw rod and the nut.When test need be taken the earthing conductor of end screen earthing device apart, nut, screw rod locking often appear together, and " working day and night " phenomenon is difficult to ground connection is taken apart.Even expense is opened end screen ground connection very energetically, when recovering, also be difficult to guarantee no longer occur " working day and night " between screw rod, the screw, be difficult to reach reliable connection.For unfamiliar new hand, also might change disconnected to the connection lead-in wire of end screen, bring hidden danger for the safe operation of electric equipment.
The utility model content
The utility model provides a kind of erosion that can prevent sleet, humidity, and detachable easy to use end screen earthing device.
A kind of detachable end screen earthing device comprises that the end screen screw rod that connects capacitance type equipment is equipped with nut, the rectangular body of an end of described screw rod.
Described screw rod is provided with housing outward.
Described housing adopts elastomeric material.
The screw rod earth terminal that the utility model shields earthing device with the end is provided with rectangular body, the end of demolition, installation very easily screen earthing device earth terminal screw, and screw rod, the loosening phenomenon of nut have not been eliminated potential safety hazard in the time of dress end screen earthing device can not occurring back; Described screw rod is provided with housing outward, prevents sleet, moist erosion, favourablely prevents to occur between screw rod and the nut corrosion locking; Therefore, the utility model is simple in structure economical and practical, realizes easily, does not need to increase extra cost, can guarantee that electric equipment normally moves, and has reduced the loss of Utilities Electric Co..
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of detachable end screen earthing device comprises that the end screen screw rod 3 that connects capacitance type equipment is equipped with nut 5, the rectangular body of an end of described screw rod 3, and the described screw rod 3 outer housings 2 that are provided with, described housing adopts elastomeric material.
The screw rod earth terminal that the utility model shields earthing device with the end is provided with rectangular body, end screen lead-in wire 1 connects capacitance type equipment, end screen ground lead 4 connects the earth connection rod, the end of demolition, installation very easily screen earthing device earth terminal screw, screw rod, the loosening phenomenon of nut have not been eliminated potential safety hazard in the time of dress end screen earthing device can not occurring back; Described screw rod is provided with housing outward, prevents sleet, moist erosion, favourablely prevents to occur between screw rod and the nut corrosion locking; Therefore, the utility model is simple in structure economical and practical, realizes easily, does not need to increase extra cost, can guarantee that electric equipment normally moves, and has reduced the loss of Utilities Electric Co..
