Remote monitoring system for transformer

Abstract

The present invention provides a remote monitoring system for a transformer. The remote monitoring system is characterized in that the remote monitoring system comprises a leakage monitor (1) and a remote server (2), the leakage monitor (1) comprises a leakage protector (4), a leakage acquisition module (5), an on-site alarm module (7), a wireless communication module (8) and a power supply module (9), the power supply module (9) is respectively connected to the on-site alarm module (7) and the wireless communication module (8) and supplies power to the on-site alarm module (7) and the wireless communication module (8), the leakage protector (4) is installed in the power supply circuit of a transformer to be detected, and the leakage acquisition module (5) is installed between the shell of the transformer to be detected and the ground.

Description

technical field [0001] The invention belongs to the field of electric equipment, and in particular relates to a remote monitoring system for a transformer. Background technique [0002] At present, various protective devices for low-voltage distribution transformers (referred to as transformers) include various high-voltage circuit breakers, lightning arresters, etc. on the high-voltage side, and various fuses, AC contactors, and phase and amplitude detection relays on the low-voltage side. Such protection measures, but due to the variety of transformer capacity levels and complex lines, it is difficult to be foolproof with various protection measures, especially the leakage fault of the transformer, which may occur in any part, and the general leakage protection is in the main circuit. Moreover, whether the leakage protection circuit is effective or not cannot be monitored in real time, which leads to the inability to detect the transformer leakage fault in time, leading to...

[0002] At present, various protective devices for low-voltage distribution transformers (referred to as transformers) include various high-voltage circuit breakers, lightning arresters, etc. on the high-voltage side, and various fuses, AC contactors, and phase and amplitude detection relays on the low-voltage side. Such protection measures, but due to the variety of transformer capacity levels and complex lines, it is difficult to be foolproof with various protection measures, especially the leakage fault of the transformer, which may occur in any part, and the general leakage protection is in the main circuit. Moreover, whether the leakage protection circuit is effective or not cannot be monitored in real time, which leads to the inability to detect the leakage fault of the transformer in time, leading to accidents, especially for transformer maintenance personnel and personnel around the transformer

[0003] Moreover, the alarm information of existing leakage monitors when leakage occurs is often either too exaggerated or not obvious enough

There is no alarm method that can remind the staff without causing too much disturbance to other staff
