High-airtightness double-door reactive compensation cabinet

Abstract

The invention provides a high-airtightness double-door reactive compensation cabinet. A reactive compensation controller is arranged inside to analyze and compare data obtained by a current mutual inductor, and a combination switch and a miniature circuit breaker are adjusted, so that a feedback loop is formed and the surge protection efficiency of a reactive compensation device is improved; structurally, a cabinet body and a top cover are assembled detachably; in terms of assembly technique, elements can be assembled through a large workpiece on the upper portion, so that installation efficiency is improved greatly; door opening and closing are achieved conveniently during high-altitude work due to the special roller shutter door design, the airtightness of a cabinet door is improved through the rubber coating design, and service life is prolonged.

Description

technical field [0001] The invention relates to the field of reactive power compensation, in particular to a high-density reactive power compensation cabinet. Background technique [0002] In reactive power compensation, the compensation accuracy reflects the efficiency of effective compensation. Low compensation accuracy will cause under-compensation or over-compensation, and a large amount of power will be consumed in this process, which will reduce the efficiency of effective compensation. When the load is relatively stable , its influence is particularly obvious; and can increase the capacity load. [0003] Reactive power compensation devices are usually used outdoors for reactive power compensation. In addition, the power consumption is large. Therefore, a reactive power compensation device with high protection efficiency and high compensation accuracy is urgently needed, and can realize reactive power compensation outdoors for a long time.

[0002] In reactive power compensation, the compensation accuracy reflects the efficiency of effective compensation. Low compensation accuracy will cause under-compensation or over-compensation, and a large amount of power will be consumed in this process, which will reduce the efficiency of effective compensation. When the load is relatively stable , its effect is particularly obvious; and can increase the capacity load

[0003] Reactive power compensation devices are usually used for reactive power compensation outdoors, coupled with large power consumption, so there is an urgent need for a reactive power compensation device with high protection efficiency and high compensation accuracy, and can achieve long-term outdoor reactive power compensation

[0004] Reactive power compensation devices in the prior art generally use surge protectors for surge protection to improve the safety of reactive power compensation devices, but their protection limits are small and cannot be applied to the needs of outdoor reactive power compensation

[0005] At the same time, the existing reactive power compensation equipment usually adopts a push-pull door opening method on the cabinet body, which is inconvenient and may cause accidents if working at high altitudes; at the same time, the push-pull door opening method cannot guarantee the airtightness inside the cabinet body, so if When working in the field, it is impossible to prevent fire and mosquitoes, etc.; in addition, the IP level and heat dissipation of the cabinet of the existing reactive power compensation equipment cannot be handled well. The higher the IP level, the higher the airtightness, and the relatively poorer heat dissipation effect. The fan will increase the input cost and also affect the overall size of the cabinet, which does not meet the installation conditions

[0006] In reactive power compensation, the compensation accuracy reflects the efficiency of effective compensation. Low compensation accuracy will cause under-compensation or over-compensation, and a large amount of power will be consumed in this process, which will reduce the efficiency of effective compensation. When the load is relatively stable , its impact is particularly obvious; and it can increase the capacity load; reactive power compensation devices in the prior art generally use surge protectors for surge protection to improve the safety of reactive power compensation devices, but the protection limit is small
