Portable 70kV full-machine deposition static test equipment

Abstract

The invention relates to a portable 70kV full-machine deposition static test device. The equipment comprises a box body, a front cover plate, a rear cover plate, handles and a generator main body, the front cover plate and the rear cover plate are hinged to the front end and the rear end of the box body respectively, the handles are connected to the two side walls of the box body respectively, the generator main body is arranged in the box body, a plurality of evenly-distributed adjusting grooves are formed in the bottom end face of the generator main body, and a plurality of buffering mechanisms are detachably connected to the inner walls of the top ends of the adjusting grooves. A balance adjusting mechanism detachably connected with the buffering mechanism is arranged in the adjusting groove. The portable 70kV full-aircraft deposition static test equipment can detect whether the generator main body is inclined in real time, obtains the inclination direction and the inclination angle, controls the balance adjusting mechanism at the corresponding position to extend or retract after calculation, and is matched with the connection angle adjustment of the universal joint, so that the test efficiency is improved. The relative positions of the generator main body and the box body can be changed, so that the generator main body inclining along with the box body is reset to a horizontal state again, and the leakage of insulating oil in the generator main body can be effectively prevented.

Description

technical field [0001] The invention belongs to the field of aircraft electrostatic protection equipment, and in particular relates to a portable 70kV full-machine deposition electrostatic test equipment. Background technique [0002] During the flight of the aircraft, its surface collides with dust, ice crystals, rain, and other material particles. Continuous collisions will cause charges to be separated from the particles and transferred to the aircraft, thereby generating a large potential at the tip of the aircraft. Electrostatic discharge occurs when the charge accumulated on the tip exceeds a certain amount, thereby creating an excessive potential difference with the charged cloud in the surrounding air. In addition, when the aircraft is refueling in the air, since the two aircraft are charged separately, the potential difference between the two aircraft due to static electricity may reach 300kV. The wide-spectrum electromagnetic field generated by the natural dissipa...

Problems solved by technology

And if there is static charge accumulation at both ends of the lead-out line of the device, because the line spacing is very small, it is particularly prone to electrostatic discharge, which will lead to the failure of aircraft navigation, communication, and computer control, and even lead to the detonation of weapons and equipment such as missiles.

[0003] Static noise control requires attention to eliminate streamer and spark noise since only corona noise is affected by ESD, noise reception may persist due to sparks between adjacent surfaces on the airframe, these fault points are difficult to find , as they are often hidden by paint or buried inside the fuselage, checking with a resistance meter can be difficult as the aluminum connectors can show DC ground but have resistance to radio frequency

[0004] At present, the common measuring equipment is mostly composed of generator body, probe assembly, power cord, grounding wire, detection meter, spare discharger, ion current generator, warning light, current collector, anti-static spray, corona ball , High-voltage cable, power cord interface, fuse interface, grounding socket, warning light interface, high-voltage probe interface, equipment switch, high-voltage output switch, high-voltage display light, voltmeter, equipment operating timetable, ammeter, emergency stop button, voltage The main body of the generator is a DC high-voltage source whose current is limited to the uA level and the output voltage is in the range of 0-70kV. It contains insulating oil inside, and it is used in the transportation, logistics, Tilting and shaking may occur during transportation and storage, which may easily cause insulating oil to overflow
