Quick switching device of duplicate power supply

Abstract

The invention discloses a quick switching device of a duplicate power supply. The quick switching device comprises a frame, a positive pole input copper bar, a negative pole input copper bar, positive pole output copper bars, negative pole output copper bars, two positive pole cylinders and two negative pole cylinders. The frame comprises an upper fixing plate, a lower fixing plate, a front fixing plate, a back fixing plate, a middle fixing plate and a middle partition plate. The positive pole input copper bar and the negative pole input copper bar are vertically installed on one side of the middle fixing plate. A pair of positive pole output copper bars is connected to the upper portion of the other side of the middle fixing plate. A pair of negative pole output copper bars are connected to the lower portion of the other side of the middle fixing plate. The end portions of telescopic rods of the two positive pole cylinders are respectively connected with contact assemblies and are correspondingly installed at the lower portions of the inner lateral faces of the front fixing plate and the back fixing plate. The quick switching device can achieve optional power supply switching of two devices.

Description

technical field [0001] The invention relates to a fast switching device for a dual power supply, which is used to solve the problem of dual power supply between one power supply and two kinds of equipment. Background technique [0002] At present, in the domestic and foreign markets, when supplying power to weld annealing equipment and full-tube annealing equipment, one VIP power supply is generally used to supply power to the weld annealing equipment alone, and the other VIP power supply is used to supply power to the full-tube annealing equipment alone; almost There is no VIP intermediate frequency power supply that supplies power to the weld annealing equipment and the full-tube body annealing equipment at the same time. powered by. [0003] The disadvantages of the above power supply methods are: [0004] 1. If the welding seam annealing equipment or the full-pipe body annealing equipment is powered separately, two VIP power supplies are required, the corresponding cos...

AI Technical Summary

Problems solved by technology

[0004] 1. If the welding seam annealing equipment or the full-pipe body annealing equipment is powered separately, two VIP power supplies are required, the corresponding cost is increased, it is uneconomical, and the utilization rate of the equipment is reduced. At the same time, one more power supply increases the volume of the equipment, so Occupies a larger plant area;

[0005] 2. Even if a VIP power supply supplies power to the welding seam annealing equipment and the full-tube annealing equipment at the same time through manual switching or closing device, it cannot realize the arbitrary switching of power supply between the equipment, and the switching time is long, labor-intensive, and there are still safety hazards. Hidden danger;

[0006] 3. Whether it is an extra power supply or manual switching, it will bring inconvenience to the maintenance and repair of the equipment

[0007] In addition, existing switching devices cannot switch power sources of different frequencies
