Description

A frame-type capacitor bank quick replacement device

technical field

The utility model relates to a quick replacement device for a frame type capacitor group, which belongs to the technical field of capacitors.

Background technique

In the reactive power compensation system of the substation, the frame type capacitor bank is widely used due to its multi-purpose (improving power factor, adjusting network voltage, reducing line loss). However, due to many reasons, such as quality problems of the capacitor itself, harmonic resonance, overvoltage, unreasonable matching of reactors, unstable performance of circuit breakers, expansion of accidents caused by improper protection devices, etc., in actual operation, capacitors fail. The phenomenon occurs from time to time, which has a huge impact on the stable operation of the reactive power compensation system of the substation.

After a capacitor fails, it is necessary to replace the faulty capacitor as soon as possible. The traditional replacement method is to remove the capacitor and hoist it out of the capacitor bank by a crane. On the one hand, the crane needs to occupy a large plane and three-dimensional space, and it needs to keep a sufficient safety distance from nearby live equipment. The capacitor bank is generally located in the relatively low-voltage equipment area of the substation, and the electrical equipment in this area is arranged closely. In order to replace the failed capacitor, it is likely to need to accompany the nearby normal operating equipment to stop; on the other hand, it is usually arranged near the capacitor bank. There are cable trenches or patrol trails, and it is difficult for the crane to park in the area close to the capacitor. When the crane is parked too far for hoisting work, it is difficult to guarantee the construction accuracy and safety. The distance between the capacitors in the frame capacitor bank is very close. Easy to collide with other capacitors. If a small crawler crane is used instead of a large crane, on the one hand, the small crane cannot pass through the net door of the capacitor bank and can only work outside the net door. Due to the high height of the net door, the working radius and range of the small crawler crane are greatly limited. On the other hand, the small crawler crane can only be parked on the grass near the capacitor bank due to its short boom, which will damage the grass in the substation. The traditional method not only occupies a large area, is inconvenient to operate, but also has a greater safety risk.

Utility model content

The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and to provide a device that can easily pass through the capacitor bank without considering the size of the work site, the scope of work, the capacitor gate and the accompanying stop of the equipment.

The support beam is made of aviation aluminum.

The support column is made of aviation aluminum.

Beneficial effects of the utility model: the utility model provides a frame-type capacitor bank quick replacement device, which can easily pass through without considering the size of the work site, the scope of work, the capacitor net door and the accompanying stop of the equipment. The net door of the capacitor bank is quickly assembled and fixed. At the same time, the hand-pulled monorail lifting trolley is used to carry out horizontal and vertical operations on the faulty capacitor. The operating point is relatively close to the lifting and fixing fulcrum, and manual operation is adopted, so the capacitor moves smoothly. It is not easy to touch other nearby capacitors, which improves work efficiency and reduces safety risks caused by improper operation of personnel.
