Description
Technical Field
The utility model relates to an electric power application technical field especially relates to 10 kilovolt cubical switchboard power cable screens device.
Background
In the transformer substation, 10 kilovolt equipment generally is the armor and removes indoor formula cubical switchboard, can divide into main bus-bar room, circuit breaker room, secondary terminal room, instrument room and cable chamber in the cubical switchboard, wherein the circuit of joining in marriage in the 10 kilovolt cubical switchboard of most is the cable chamber that 10 kilovolt power cable inserted in 10 kilovolt cubical switchboard, and cable terminal and cable chamber copper bar (aluminium row) are drawn the line and are connected with the bolt, guarantee 10 kilovolt power cable and connect the fastening, steady power transmission.
According to the 5 th minute book of the national grid company transformer maintenance management regulation (trial run): item 1.3.2 of the switchgear examination and repair rules: the reference period of the switch cabinet and the internal equipment is 35kV and below 4 years. Therefore, class C service and routine testing of 10 kv cables is performed every 4 years to ensure that the 10 kv cables are operating properly.
At present, when a 10 KV power cable is subjected to C-type maintenance and high-voltage test, a maintainer opens and removes a bolt of a power cable terminal (hereinafter referred to as a cable head) in a switch cabinet and a copper bar (aluminum bar) in a cable chamber to lead the cable, but the self weight of the cable head is large due to the narrow implementation space in the switch cabinet, and after the cable head is separated from the busbar, the situation that the cable integrally slides into a cable trench at the lower part of the switch cabinet is easy to occur, so that the maintainer needs to take relevant measures for preventing the cable from sliding down integrally. General case, the maintainer can take three kinds to prevent the whole landing measure of cable: (1) the maintainer demolishs the double-phase of three-phase cable head, and another looks is not demolishd and is prevented the cable landing. The disadvantage of doing so is that the single-phase cable bears the weight of the whole cable, which damages the cable; secondly, the cable can only be subjected to split-phase test, the integral test cannot be carried out, and test data are inaccurate; (2) the maintainer uses the haulage rope, ties cable three-phase bifurcation department on fixed framework. The disadvantages of this method include that although a three-phase cable test can be performed, the existence of the hauling rope requires consideration of the test position to prevent ground discharge during the test, and due to the narrow space, the hauling rope is not easy to find a proper fixing frame; (3) the cable three-phase is completely dismantled and placed in a cable trench for high-voltage test, and the defect that when a three-phase cable is reinstalled, an operator needs to enter the cable trench below a switch cabinet, straighten the cable from the trench to a hole of the switch cabinet again, and pull the cable by ground personnel at the same time to reconnect the cable is overcome.
The three methods not only waste a large amount of manpower and time, but also easily cause collision accidents due to space limitation and complicated cables in the cable trench, and even cause human casualties if the collision is mistakenly caused by accidental intervals. Therefore, the utility model provides a 10 kilovolt cubical switchboard power cable screens device to solve the weak point among the prior art.
