Nuclear phase device and electroscope used in cooperation with nuclear phase device

Abstract

The invention relates to a nuclear phase device and an electroscope used in cooperation with the nuclear phase device. The nuclear phase device comprises a chassis vehicle, a vehicle body and at least one leaf electrometer arm, wherein the two sides of the chassis vehicle are provided with an interlocking device used for opening a high-voltage switch cabinet insulating baffle and a grounding device being matched with a grounding insertion hole of a high-voltage switch cabinet respectively, the vehicle body is perpendicularly fixed on the chassis vehicle, each leaf electrometer arm is arranged to be parallel to the chassis vehicle, one end of each leaf electrometer arm is fixed on the vehicle body, and the other end of each leaf electrometer arm makes contact with a power supply fixed contact of the high-voltage switch cabinet; each leaf electrometer arm comprises a contact arm, a contact and metal rod, wherein the contact and the metal rod are fixed at the two ends of the contact arm, the contact is matched with the power supply fixed contact and suitable for being inserted into the power supply fixed contact, the conductive connection between the contact and the metal rod is achieved through the contact arm, and the metal rod perpendicularly penetrates through the inner side faces of the vehicle body and penetrates out from the outer side face. When nuclear phase is performed, an operating worker uses a leaf electrometer rod or the electroscope to probe the interior of a leaf electrometer inserting hole, then the nuclear phase is directly performed, the problem that in the prior art, when faults occur to a sensor and other components, an actual voltage signal can not be acquired to perform the nuclear phase is solved, and safety accidents are avoided.

Description

Technical field [0001] The invention relates to a nuclear phase device and an electroscope used in conjunction with the nuclear phase device, in particular to a nuclear phase device used in a high-voltage switch cabinet and an electroscope used in conjunction with the nuclear phase device. Background technique [0002] In the power operation of the power system, when two power sources need to supply power to the same electrical equipment, phase verification should be performed at the parallel point to prevent inconsistent phase sequence (phase) from causing short-circuit accidents. [0003] In the prior art, the nuclear phase of the 10KV high-voltage switchgear needs to be carried out by two groups of personnel at the same time, who are respectively responsible for measuring the phasors of the two power supply voltages of I and II, and then comparing them. Take the measurement of the A phase power supply voltage of No. I as an example: one person manually uses an insulating brake l...
