Description

A transformer secondary terminal grounding monitoring and alarm device

technical field

The invention relates to the field of electric power technology, in particular to a monitoring and alarming device for secondary terminal grounding of a transformer.

Background technique

The transformer is the key equipment of the preventive test, and the dielectric loss and capacitance test can effectively find the defects such as damp and deterioration of the insulation of the transformer. When the transformer is running, the outermost end screen must be reliably grounded, but the dielectric loss and capacitance test must be removed from the secondary terminal of the end screen of the transformer to be grounded. This necessary operation will cause the test work to be completed and forget to restore the second time. Safety risk of terminal grounding.

In order to remind the operators to prevent the grounding of the secondary terminal from being missed due to the end of the preventive test, the applicant provided a device for forgetting to restore the grounding of the secondary terminal of the transformer (patent application number is 202110333920.5), which includes a fixer, a wireless monitor , the connecting terminal piece, the first connecting piece and the second connecting piece; the connecting terminal piece is connected with the fixer through the first connecting piece, and is used to be fixed on the dismantled secondary terminal to serve as a reminder; the wireless monitor passes through the second The second connecting piece is connected with the fixer in an adjustable monitoring angle, and is used for collecting wiring image information. The working method is: after the on-site test personnel disassemble the end screen of the transformer and ground it, fix the holder above the secondary panel, and fix the connecting terminal on the secondary terminal, which can remind in time to avoid the omission of the secondary terminal after the preventive test is over. The terminal is grounded. Then bend the wireless monitor to a suitable monitoring angle so that it can monitor the entire secondary panel, and the person in charge can remotely connect to the wireless monitor through a smart terminal such as a mobile phone, and then can timely and clearly check the wiring status of the test line and To restore the wiring situation, there is no need to climb the escalator repeatedly, and the situation before the wiring is removed and after the wiring is restored can be taken remotely in time and recorded separately, which is convenient for subsequent work records.

However, in this solution, the connection terminal needs to be connected to the holder through the first connecting piece, and the wireless monitor needs to be connected to the holder through the second connecting piece, so there are problems that the connecting piece is easy to knot and difficult to organize. In terms of the reminder method, the scheme fixes the connection terminal on the secondary terminal or further adds a timing reminder to remind to avoid the completion of the preventive test and omit the recovery of the secondary terminal grounding. This reminder method requires the field test personnel to visually observe the secondary terminal. Whether the terminal is grounded or not, the automatic detection of whether the secondary terminal is grounded cannot be automatically realized, and the degree of intelligence is low.
