Problems solved by technology

[0006] In foreign countries, ABB, Siemens, GE and other companies have produced spark gaps for 500kV ultra-high voltage series compensation, but due to their different trigger ignition principles, the structure and function must be quite different
In addition, the spark gap and its trigger circuit equipment are arranged on the series compensation platform, which is in a high potential environment, and the electromagnetic environment is relatively complicated

Embodiment 1

[0039] Such as Figure 1-2 As shown in the figure, the main steps of the inventive method for obtaining the spark gap triggering energy of the invention in this example are first converting the line current into a secondary current through a current transformer; Secondary conversion processing, so as to meet the requirements of the subsequent circuit; rectify the obtained current into DC, and charge the capacitor; monitor the capacitor voltage in real time during the charging process of the capacitor, and maintain the voltage at a certain level through the hysteresis control method; when the capacitor When the charging is abnormal, an alarm signal is sent to provide reference for maintenance.

[0040] The specific method is as follows: the line current is converted into a smaller secondary current i through the current transformer 1 , and connect the secondary output side of the current transformer to the spark gap trigger control box through a shielded cable, and the outer l...

Abstract

The invention relates to a series compensation spark gap trigger energy acquisition system and an acquisition method thereof. The system and method realize the trigger energy acquisition of the spark gap on the series compensation platform through the current transformer connected with each other by the shielded cable and the spark gap triggering the transformer, the charging circuit and the monitoring circuit inside the spark gap trigger control box, and propose a highly reliable method at the same time. Sexual implementation circuit.

Description

[0001] Technical field: [0002] The invention relates to the field of spark gap trigger energy acquisition, and more particularly relates to a series compensation spark gap trigger energy acquisition system and an acquisition method thereof. [0003] Background technique: [0004] In the power system, the spark gap for series compensation belongs to the mandatory trigger gap, and the generation of ignition pulse in the trigger process requires a certain trigger energy. The spark gap for series compensation is the main protection of the voltage limiter MOV and the backup protection of the capacitor bank. As a key primary device for series compensation, the spark gap must have extremely high working reliability. Therefore, how to obtain the trigger energy and develop a high-reliability circuit is one of the key technologies of the spark gap, which is related to the method of obtaining the trigger energy and the design of the related circuit system, which is related to whether t...
