Embodiment Construction
[0012] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0013] The invention is a mobile adjustable three-phase unbalance control device, such as figure 1 As shown, it includes a bracket 1 , a mounting plate 2 , a three-phase unbalance control device body 3 and a shelter 4 .
[0014] The mounting plate 2 is fixed laterally on the bracket 1 and is used to support the body 3 of the three-phase unbalance control device correspondingly.
[0015] The canopy 4 is obliquely fixed on the bracket 1 and is located above the three-phase unbalance control device body 3, which is used to protect the three-phase unbalance control device body 3 at the top and play a certain role of moisture-proof and moisture-proof .
[0016] The two sides of the mounting plate 2...

The invention discloses a movable adjustable three-phase imbalance treatment device which comprises a support, a mounting plate, a three-phase imbalance treatment device body and a rain shelter. The mounting plate is transversely and fixedly arranged on the support, the three-phase imbalance treatment device body is arranged above the mounting plate, and the rain shelter is obliquely fixed to the support and located above the three-phase imbalance treatment device body. Concave sliding grooves are formed in the two sides of the mounting plate respectively, sliding wheels are arranged on the two sides of the bottom of the three-phase imbalance treatment device body respectively and correspondingly arranged in the sliding grooves, a displacement air cylinder is further arranged in the middle of the upper surface of the mounting plate, and the piston end of the displacement cylinder is correspondingly fixed to the bottom of the three-phase imbalance treatment device body. The device is simple, reasonable and reliable in structure, adjustable in movement and good in stability, the position of the device can be adjusted according to temperature and humidity, and the use safety is improved.
Description
technical field [0001] The invention relates to a mobile adjustable three-phase unbalance control device. Background technique [0002] The three-phase unbalance control device is a new type of power electronic device used to dynamically control the three-phase unbalance of the distribution network and compensate reactive power. Current, use advanced control algorithm to separate the positive, negative, zero sequence and reactive power of unbalanced current, and trigger the power device IGBT to make the inverter send out the opposite offset current, so as to eliminate unbalance and compensate reactive power. The existing three-phase unbalance control devices are usually exposed and fixed outdoors, and cannot be adjusted. The long-term influence of rain and snow will easily make the internal components damp, resulting in failure to work normally. Contents of the invention [0003] The purpose of the present invention is to provide a mobile adjustable three-phase unbalance ...
