Description

Technical Field

[0001] The utility model relates to the field of electric energy transmission, in particular to an intelligent voltage instantaneous compensation transformer device. Background Art

[0002] In many cases, when the transmission line is too long from the transformer or there is power shaking on site, it will cause voltage drop or loss of voltage, making the load-end motor unable to work normally. The conventional practice is to increase the specifications of the transmission cable or add a motor restart device to ensure the normal working level of the motor, but this method is costly and the construction is troublesome and complicated. The voltage transient compensation transformer device can solve this problem and has protection functions. It can adjust the voltage output, control the three-phase voltage imbalance, and resist power shaking to meet the needs of multiple occasions.

[0003] In the existing technology, the intelligent voltage transient compensation transformer device is composed of several major parts such as IGBT monitoring and control module, protection module, double reverse thyristor, inverter output module, bypass static switch, etc. Its IGBT monitoring and control module can continuously monitor the input voltage waveform, and can detect the waveform when it deviates from the set range or the predetermined time. If an overvoltage occurs, its protection module will take effect. The protection value can be set on the operation interface. When the voltage is higher than the set value, an alarm will be issued and the line will be cut off. If there is a fault or maintenance, the load current will be automatically transferred to the bypass static switch to ensure the safety of equipment and personnel. However, the existing intelligent voltage transient compensation transformer device has certain limitations during use. Limitations, in order to prevent electric shock accidents and ensure the safety of staff, before opening the equipment cabinet door, it is necessary to disconnect the circuit breaker or isolating switch to allow the discharge device of the equipment cabinet to discharge, and the existing equipment cabinet door is usually opened directly before opening, which is less safe. In addition, since there are a large number of components in the equipment cabinet that are energized during use, a lot of heat is generated during operation, and a heat dissipation device is required to dissipate the heat. Due to the long-term use of the heat dissipation device, there is a phenomenon of damage to the heat dissipation device. These devices are usually installed in a fixed form on the equipment cabinet. The disassembly, maintenance and subsequent reinstallation operations are relatively cumbersome, easily waste a lot of time, and are inefficient. Therefore, an intelligent voltage instantaneous compensation transformer device is proposed to solve the above problems. Utility Model Content
