Auxiliary wiring device for high-altitude high voltage tests

Abstract

The invention belongs to the field of high-altitude high voltage tests and particularly relates to an auxiliary wiring device for high-altitude high voltage tests on transformer station high voltage electrical equipment. The device comprises a metal hook, an insulation rod, a supporting rod, a lifting rod, a traction rope, a fixed pulley or a directional shaft, and a sliding rail. A rod body of the lifting rod is provided with a traction point for fixing the traction rope, when a high voltage leading wire lifting assembly is in a natural suspension state, an arrangement height of the fixed pulley or the directional shaft is not lower than height of the traction point at the lifting rod portion when the supporting rod is in a horizontal state, an upper side rod face of the lifting rod forms a supporting face for supporting a high voltage leading wire when the lifting rod is in a horizontal state, and a sliding rail face of the sliding rail faces towards the direction of the supporting rod and is in a travel path of the lifting rod guided by the traction rope. The device is advantaged in that the device is convenient and rapid to use, and influence of miscellaneous capacitance on a high-altitude high voltage test data result can be greatly reduced.

Description

technical field [0001] The invention belongs to the field of high-altitude high-voltage testing, and in particular relates to a wiring auxiliary device for high-altitude high-voltage testing of substation high-voltage electrical equipment. Background technique [0002] High-voltage test is an essential step for health inspection of electrical equipment. The accuracy of the test data and whether the test task can be completed within the specified time is the key to ensure the operation and emergency repair of high-voltage circuit breakers, high-voltage metering, high-voltage lines, high-voltage cables and other equipment. An important evaluation indicator for the safe and successful completion of work. At present, the most commonly used test method for high-altitude electrical equipment is to directly connect the high-voltage lead wire to the equipment under test installed at high altitude; if the high-voltage lead wire is too long, use an insulating tape to fix the high-volt...

AI Technical Summary

Problems solved by technology

However, even under the action of oblique tension, the high-voltage lead still presents an acute angle with the electrical equipment under test, that is, the upper half of the high-voltage lead will still be affected by miscellaneous capacitance

In order to increase the above-mentioned acute angle as much as possible, the use of insulating tape to pull and fix the high-voltage leads obliquely usually still requires the use of climbing tools to maximize the angle of the high-voltage leads relative to the electrical equipment under test; this not only brings safety hazards to field work , various fixed facilities will increase the workload of the testers no matter from transportation or on-site use, which will bring great troubles to the testers
