The utility model discloses a ground connection that the connector that sets up on the earthed pole and the threaded connection of earth connection plug realized the earth connection, simple to operate is swift, the T type contact and the connector terminal surface dead contact of installation in the earth connection plug moreover, set up spring on T type contact can guarantee T type contact all the time with the terminal surface in close contact with of connector, guarantee the good nature of contact, moreover, T type contact has increased area of contact, has reduced ground resistance. The utility model discloses the contact is good, connects firmly, can not take place not hard up phenomenon, and operating personnel's safety has been guaranteed to the reliable ground.

Description

Distribution network line maintenance grounding discharge device
Technical field
The utility model belongs to distribution network line repair apparatus technical field, is specifically related to a kind of distribution network line maintenance grounding discharge device.
Background technology
According to " electrical safety working regulation " regulation, 10kv distribution line and equipment, when interruption maintenance, must fulfil the measure that " power failure, electrical verification and installing earth connection " ensures safety.Earth connection (i.e. earthing device) is exactly the wire of tieline road or equipment and the earth, also can be called safety return circuit line, and time dangerous, it just switches through high voltage direct and marries the earth, is ensure electricity
Lik-Sang produces a lifeline of worker at the production line's safety.
Connection between the earth connection hung during current distribution line interruption maintenance and earth rod connects by bolt; According to the requirement of State Grid Corporation of China in earth connection keeping maintenance, use earth connection earth rod to be pulled down at every turn, independent sealing keeping, avoid corrosion, so just make in work progress, to install and remove earth connection time-consuming, the contact area (only having bolt junction) less than normal of earth rod and earth connection, makes the earth resistance of whole earthing device bigger than normal simultaneously at every turn, earthing effect is bad, also there will be loosening phenomenon.According to investigation and analysis before, find following problem: the contact area S of (1) earth connection and earth rod is less, make earth resistance bigger than normal; (2) the connecting bolt trouble of earth connection is installed and removed, consuming time longer; (3) connected mode can not ensure that the connection of earth rod and earth connection is each all reliable, easily occurs loosening phenomenon.
Such connected mode can not ensure that the connection of earth rod and earth connection is each all reliable, the requirement that the earth connection not reaching regulation in " safety " " must contact good, connect reliable ".Therefore improve existing 10 KV grounding wires, effectively reduce earth resistance, can ensure safety ground further, make connection procedure firmly easy simultaneously, guarantee the safety of the person and equipment, stopping the generation of electric shock casualty accident, is very necessary.
Utility model content
For above-mentioned deficiency described in the prior, the purpose of this utility model is to provide a kind of easy installation and removal, and contact area is large, and earth resistance is little, contacts well firm distribution network line maintenance grounding discharge device .
For realizing above-mentioned technical purpose, the technical scheme that the utility model adopts is as follows:
A kind of distribution network line maintenance grounding discharge device, comprise earth brace and earth connection plug, earth connection plug is threaded with the connector of earth brace; The T-type contact element contacted with connector is provided with in earth connection plug; T-type contact element is provided with the electric-conductor for being connected with earth connection.
Described earth connection plug comprises header body and T-type contact element, and be provided with internal thread in header body, T-type contact element is arranged in header body, and one end of T-type contact element is protruding through header body; T-type contact element in header body is provided with spring, the T-type contact element outside header body is provided with for the electric-conductor be connected of connecting wires.
Connector is provided with the external screw thread matched with header body internal thread.
Insulating barrier is provided with in the outside of header body.
The utility model is grounded the ground connection of line by the connector arranged on earth brace with being threaded of earth connection plug, quick and easy for installation, and the T-type contact element of installing in earth connection plug contacts completely with connector end face, the spring be arranged in T-type contact element can ensure T-type contact element all the time with the end face close contact of connector, ensure the formedness of contact, and T-type contact element increases contact area, reduce earth resistance.Electric-conductor realizes the connection with earth connection, and T-type contact element, connector and earth brace are electric conducting material and make.The utility model contact is good, and stable connection, loosening phenomenon can not occur, reliable ground, ensure that the safety of operating personnel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
