Embodiment Construction

[0034] It should be noted that the orientations or positional relationships indicated by the terms "lower part", "middle part", "top", "tail", "left side", "right side" and "lower side" in the patent specification of the present invention are based on the drawings The orientation or positional relationship shown, the "normal power supply" and "backup power supply" are only for the convenience of describing the present invention, and do not indicate or imply that the referred device or element must have a specific orientation or be constructed in a specific orientation. and operation, and therefore should not be construed as limiting the invention.

[0035] combine Figure 1 to Figure 13 , the present invention will be further described through specific examples.

[0036] A PC-level dual power automatic transfer switch, such as figure 1 As shown, it includes the installation base plate, the common power conversion operating mechanism 1 set on the right side of the installatio...

Abstract

The invention relates to a PC-level dual-power automatic transfer switch, Includes mounting base plate, A common power supply electromagnet conversion operating mechanism and a standby power supply electromagnet conversion operating mechanism are arranged on both sides of the mounting base plate, and an arc extinguishing chamber and a dual-power intelligent controller arranged on the mounting bottom plate and on the upper part of the contact system, As the double power supply adopts the lever-connecting rod operating mechanism with special structure, When the dual supply side is in place, themechanism automatically locks the closing position by the reverse torque of the actuating link, At that same time, the mechanism can increase the contact pressure when the switch is closed and the contact open distance when the switch is opened, so that the dual power supply has excellent electric performance and the work stability of the dual power supply is greatly improved.

Description

technical field [0001] The invention relates to a low-voltage electrical appliance, in particular to a PC-level dual-power automatic transfer switch. Background technique [0002] Dual power automatic transfer switch is a commonly used low-voltage electrical appliance, usually used to switch between two power sources, to ensure that when one power source fails or stops supplying power, it can quickly switch to another power source to ensure the normal power supply of the load circuit , this kind of dual-power automatic transfer switch is generally composed of a conversion operating mechanism and an electrical control part. Due to the limitation of the conversion operating mechanism, the traditional PC-level dual-power automatic transfer switch has insufficient working stability, and its short-term withstand current is not enough. It restricts the development of PC-level dual power automatic transfer switch. Contents of the invention [0003] The purpose of the present inv...
