Description
Technical Field
The utility model belongs to electric power system auxiliary device field, concretely relates to test wire high altitude termination.
Background
At present, when primary equipment such as 35kV and above high-voltage circuit breakers, voltage transformers and the like in a transformer substation are tested, two auxiliary modes of hanging a test line are mainly adopted: the high-altitude operation vehicle or the high-altitude wiring clamp is adopted. The actual current situation is that the number of overhead working trucks is limited, and it takes a few hours, even two or three hours, to reach the working site, and the labor cost of the drivers of the overhead working trucks is increased. Based on the above consideration, the high-altitude work vehicle is replaced by the high-altitude wiring clamp in most cases. The high altitude binding clip who has used has the aspect of carrying, advantage that the practicality is strong, however along with a large amount of uses in the work, the weak point of current high altitude binding clip also shows gradually:
(1) the high-altitude jointing clamp needs to be jointed in multiple sections for convenient carrying. At present, high-altitude wiring pliers are spliced, iron threads are arranged at joints, and the length of a single section is 1 meter. The height of a wiring board of primary equipment such as a high-voltage circuit breaker of 35kV or more is at least 3 meters, particularly the height of an upper wiring board of the primary equipment with the voltage class of 220kV is 8 meters. In order to complete the connection of the test wire, the overhead wiring clamp needs to be spliced on site, the average time is 7 minutes, and if the joint is rusted, the splicing time is longer and reaches 10 minutes. The splicing operation seriously influences the test progress, and further increases the economic loss of power failure maintenance.
(2) The high-altitude wiring clamp is made of epoxy resin materials, the self weight of the high-altitude wiring clamp reaches 5.6kg, and if the weight of the test wire is added, the overall weight of the high-altitude wiring clamp reaches 8 kg. Meanwhile, the length of the whole jointing clamp is 7 meters, and according to a moment formula, if the jointing clamp is operated by a single person, a heavy object which is as important as 70kg is erected, so that the jointing clamp is difficult to erect by the single person, and at least two persons are needed to erect the jointing clamp in the field operation process.
(3) The test wire and the high-altitude jointing clamp only have two fixed points with the distance of 18mm at the jaw, and the condition that the test wire swings exists in the hanging process, so that the fixed point of the jaw is likely to be disconnected due to the action of the self weight of the test wire, and the test wire is further failed to be hung. Meanwhile, the swing of the test wire can make the whole high-altitude wiring clamp unstable, so that the high-altitude wiring clamp has the risk of toppling over and has great potential safety hazard.
