Embodiment Construction

[0025] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0026] The invention discloses a mobile impulse voltage test device. When the test is not being carried out, the tower of the high-voltage impulse generator is driven by lifting the bottom plate, and the high-voltage impulse generator arranged on the tower lies flat on the side of the movable device. In the cabin, when the test is being carried out, the tower of the high-voltage impact generator is vertically turned over by turning the lifting bottom plate vertically so that it can be erected on the ground, thereby realizing the automatic deployment of the test equipment without the need for external hoisting equipment, etc. to lift the tower It s...

Abstract

The invention discloses a movable type impact voltage test apparatus. The apparatus comprises a movable device with a cabin, a supporting base plate that is disposed in the cabin and can vertically overturn in the cabin, a high-voltage impact generator tower that is parallel to the supporting base plate, a high-voltage impact generator disposed on the tower, a locking unit disposed between the supporting base plate and the tower, and a supporting plate for supporting the tower. The test apparatus is capable of outputting 2100kV oscillation impact lightning waves and 1800kV oscillation impact operation waves with the impact energy greater than 230kJ, thereby meeting on-site impact test requirements of a 1000kVGIS and other extra-high-tension electrical devices. The apparatus is high in integrated automation, enables the work efficiency to be substantially increased, and is safe, reliable and convenient.

Description

technical field [0001] The invention relates to the field of high voltage impact test, in particular to a mobile impulse voltage test device. Background technique [0002] In addition to the power frequency voltage of normal operation, the high-voltage electrical equipment in the power system may also be attacked by temporary overvoltage and lightning overvoltage. Lightning may cause overvoltage with a high amplitude or slope on the transmission line or power equipment, which will greatly damage the insulation of the equipment. In engineering, it is often necessary to use an impulse voltage generator to simulate a lightning strike test to test the ability of electrical equipment to withstand lightning overvoltage. Traditional impulse voltage generators are generally bulky, with many components and components, and are generally fixedly installed in the test hall for use. During the field test, in addition to solving the problem of safe transportation and loading and unloadi...
