Switch

Abstract

A switch disclosed by the present invention comprises a base, a large cover, a surface cover, a static contact, a moving contact, an insulating rotating shaft, an arc extinguish chamber, an operating mechanism and an electronic controller, the electronic controller comprises a power supply module, a first cavity is formed between the base and the large cover, at least one second cavity is formed between the large cover and the surface cover, a power transformer of a power module is arranged on one side, close to a wire inlet end, of an operating handle along the length direction of the switch; and an energy storage farad capacitor of the power supply module is arranged on any side of the operating handle along the width direction of the switch or is arranged in the second cavity on one side of the operating handle close to the wire inlet end along the length direction of the switch. The switch can separate strong current and weak current of a product circuit board, concentrate high-power heating elements, improve temperature rise of the circuit board, improve electromagnetic compatibility design of the circuit board, and is high in reliability.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to an electric switch. Background technique [0002] As the State Grid continues to promote the construction of the ubiquitous power Internet of Things, various products in the power system are continuously upgraded and upgraded. In addition to maintaining the original protection functions such as overload and short circuit, the switch also adds functions such as electrical quantity data detection, communication, and data display. . In order to realize these new functions, it is necessary to add communication modules, more electronic controllers, display modules, high-precision and wide-range current acquisition modules, and voltage acquisition modules. The addition of various modules makes the cavity size of the switch unable to accommodate such a large number of modules, and peripheral devices such as backpack switches and LTUs are derived. The increase of equipm...
