Description

Technical Field

[0001] The invention belongs to the field of low-voltage distribution networks, and in particular relates to a multi-channel arc generating device. Background Art

[0002] As a key link directly facing the vast number of users, the safety, stability and rapid recovery of the distribution network after faults have received more and more attention, and it has extremely important practical significance for the safe and stable development of the urban economy. In the distribution network, when a single-phase grounding fault occurs in the system operation, the voltage of one phase to the ground where the fault occurs will drop, while the voltage of the other two phases to the ground and the zero-sequence voltage at the neutral point will rise, so that the three-phase voltage to the ground in the system will no longer be balanced. However, the line voltage will continue to maintain the original symmetrical operation in a short time, and will not have a significant impact on the power supply of users. At this time, if the arc is not extinguished, that is, the discharge arc continues to exist at the fault point, it may cause further expansion of insulation damage and may also cause arc overvoltage. The resulting overvoltage lasts for a long time and runs through the entire network, which will cause insulation breakdown, resulting in a short-circuit fault between phases, which will have a serious impact on personal safety, user power supply and related equipment.

[0003] In the arc generating device simulating single-phase grounding fault in the low-voltage distribution network, a manual rotating roller or a stepper motor is often used to realize the movement of the nut in the screw nut mechanism, thereby controlling the distance between the two electrodes of the arc. Manually twisting the roller during the arc drawing process may cause electric shock and breakdown of the signal line; the stepper motor controller and the host computer need to use CAN / 485 communication, which is limited by the length of the signal line and the power line and cannot be operated remotely. In order to solve the above problems, the patent application with publication number CN117269687A discloses an arc action execution and acquisition monitoring system based on 4G communication technology, in which the single-phase AC 220Vac-50Hz is boosted to 690Vac-50Hz by an autotransformer, and is connected to the AC circuit breaker, the AC arc drawing device and the load resistor in sequence. The action of the arc control device sends a distance instruction to the servo motor controller through the 4G communication module, which controls the servo motor to drive the screw nut to move, thereby controlling the distance between the two electrodes of the arc. The voltage transformer and current transformer collect arc voltage and arc current respectively, and transmit them to the host computer through voltage transmitter, current transmitter, 485 / CAN to USB to display the curve. This system solution realizes the remote control of arc drawing device, the collection and display of arc data, and the controllability of arc length, reducing the risk of electric shock.

[0004] However, the current arc generating device still relies on external power supply to the pinion drive motor to realize the rotation of the gear reducer; the energy replenishment of the main battery also relies on external power supply, and the real-time distance between the two electrodes cannot be perceived, which is limited in certain field operations or application scenarios with limited external power supply.

[0048] A hexagonal boss is upwardly arranged in the middle of the lower support base plate 30, and a group of stationary electrodes and their fixing flanges 50 are respectively arranged on each side of the hexagonal boss.
