Description

Technical Field

[0001] The invention belongs to the field of static VAR generators, in particular to a static VAR generator with good protection and convenient maintenance. Background Art

[0002] In current life, static reactive generators connect the self-commutated bridge circuit to the power grid through a reactor or directly in parallel, adjust the phase and amplitude of the output voltage on the AC side of the bridge circuit, or directly control the current on the AC side, so that the circuit absorbs or emits reactive power that meets the requirements, and achieves the purpose of dynamic reactive compensation. Reactive compensation devices should be installed in all places where low-voltage transformers are installed and next to large electrical equipment, especially those industrial and mining, enterprises, and residential areas with low power factors. Large asynchronous motors, transformers, electric welders, punching machines, lathes, air compressors, presses, cranes, smelting, steel rolling, aluminum rolling, large switches, electric irrigation equipment, electric locomotives, etc. are particularly needed. In addition to incandescent lighting, air conditioners, refrigerators, etc. in residential areas are also consumers of reactive power that cannot be ignored. The power supply situation in rural areas is relatively poor. In most areas, the power supply is insufficient, the voltage fluctuates greatly, and the power factor is particularly low. Installing compensation equipment is an effective measure to improve the power supply situation and increase the utilization rate of electric energy.

[0003] However, most of the existing static VAR generators are not equipped with corresponding protective mechanisms, such as heat dissipation mechanisms and shock-absorbing mechanisms, which results in the static VAR generator being unable to dissipate heat in time when in use, thereby seriously affecting the service life of the equipment. At the same time, when it is transported, due to the lack of a shock-absorbing mechanism, the internal components cannot be protected, which causes vibrations to the electronic components inside the equipment during transportation, and the screws are prone to loosening. In addition, the existing static VAR generator housings are mostly directly connected by screws. When they are damaged, the screws need to be unscrewed to repair the inside, which is more troublesome. At the same time, repeatedly twisting the screws is likely to cause thread slippage, which is not conducive to actual use. Summary of the invention
