Low-voltage dual-mechanism dual-power high-speed switch switching device

Abstract

The invention discloses a low-voltage dual-mechanism dual-power high-speed switch switching device, which comprises a shell, two insulating mounting cylinders fixedly mounted at the top of the shell and switching switch mechanisms fixedly mounted in the shell and the insulating mounting cylinders respectively, and relates to the technical field of power switching equipment. According to the low-voltage dual-mechanism dual-power high-speed switch switching device, all-around anti-interference design can be carried out on the shell and the insulating sleeve of the switching device, so that the switching device can protect internal interference and external environment electromagnetic interference at the same time in the whole switching process; electromagnetic protection structures are respectively designed and installed on an external protection shell part of the switch device, and meanwhile, an electromagnetic anti-interference structure is also designed outside double arc extinguishing chambers, so that electromagnetic isolation of double power supplies is realized, the safety of the switch is greatly improved, and meanwhile, the whole switch device has very good heat insulation and anti-collision effects by designing a heat insulation and anti-collision mechanism.

Description

technical field [0001] The invention relates to the technical field of power switching equipment, in particular to a low-voltage dual-mechanism dual-power high-speed switching device. Background technique [0002] At present, due to the failure of the external network, the system will produce "power shaking" or "power loss", which will easily cause shutdown of sensitive loads, voltage fluctuations and short-term power supply interruptions, resulting in large economic losses or negative social impacts. Dual power supplies are adopted. The switching method is a solution to the above problems. The current dual power supply switching solutions on the market include: [0003] Ordinary switch switching scheme: due to the slow switching time and the slow detection time of the controller (the whole switching time is generally 50--80ms), the following hidden dangers are likely to be caused due to the long time of power shaking or power loss: [0004] 1. Cause shutdown of sensitive l...

Problems solved by technology

[0014] Aiming at the deficiencies of the prior art, the present invention provides a low-voltage dual-mechanism dual-power high-speed switch switching device, which solves the problem that the existing switch has a small capacity, a limited range of use, and a large volume, which cannot be installed and used in some occasions. The environmental requirements are high, and it must be used in an indoor constant temperature environment. The failure rate is high, the maintenance cost is high, and it does not have breaking capability. At the same time, the electromagnetic protection structure, heat insulation mechanism and The anti-collision safety protection structure, and the electromagnetic anti-interference structure is also designed in the double arc extinguishing room to realize the electromagnetic isolation of the dual power supply and greatly improve the safety of the switch
