Distribution transformer portable gear control and regulation device

Abstract

The invention discloses a distribution transformer portable gear control and regulation device. A power supply module is installed in an external shell. The power supply module is connected with a motor control circuit which is connected with a driving motor. The driving motor is connected with a gear transmission shaft which is connected on a transformer gear shifting wheel. The motor control circuit is also connected with a gear control and display device which is connected with a remote signaling acquisition module. The remote signaling acquisition module is connected with a wireless communication module which is connected with a distribution network intelligent monitoring server through a wireless network. The output end of the motor control circuit is connected with the gear control and display device through an RJ45 ethernet port so as to locally monitor and regulate the transformer gear in real time. The signal output end of the remote signaling acquisition module is also connected with the wireless communication module which is connected with the remote distribution network intelligent monitoring server so as to remotely transmit gear information and operate the distribution transformer gear.

Description

technical field [0001] The invention relates to a gear control and adjustment device for a transformer, in particular to a novel portable gear control and adjustment device for a distribution transformer. Background technique [0002] At present, most of the small and medium-sized distribution transformers used in townships and factories are not equipped with on-load voltage regulating devices, and manual adjustment is generally used for transformer shifting. It does not meet the need for frequent adjustments and the work efficiency is low, which affects the voltage quality at the end of the line and easily arouses public opinion on power supply from customers. The output point of the measurement and control device and the on-load voltage regulation gear controller circuit are combined to jointly control the main transformer on-load voltage regulation mechanism. Due to the rapid and frequent changes in the voltage of the distribution network, the gear adjustment of the dist...

Problems solved by technology

[0002] At present, most of the small and medium-sized distribution transformers used in townships and factories are not equipped with on-load voltage regulating devices, and manual adjustment is generally used for transformer shifting. It does not meet the need for frequent adjustments and the work efficiency is low, which affects the voltage quality at the end of the line and easily arouses public opinion on power supply from customers

Due to the rapid and frequent changes in the voltage of the distribution network, the gear adjustment of the distribution transformer is very frequent. Some transformers need to adjust the gear more than ten times a day, which can easily cause damage to the on-load voltage regulation gear controller, which greatly reduces the transformer and control. service life of the device

After the controller is damaged, the on-load voltage regulation gear of the main transformer cannot be operated, which seriously affects the voltage qualification rate and other indicators.
