Electric switch

Abstract

An electric switch comprises an insulating shell, the insulating shell comprises a base, an insulating cover and a surface cover which are sequentially arranged, a moving contact, a static contact, a rotating shaft, an arc extinguish chamber, an operating mechanism, a handle, a current collector, an electronic controller and a communication module are arranged in the insulating shell, and a cavity is formed between the insulating cover and the surface cover. A cavity is formed in the surface cover, a substrate of at least one electronic circuit board of the electronic controller is arranged in the cavity, the surface cover is provided with a ladder-shaped or ladder-shaped longitudinal concave cavity for accommodating movement of the handle and manual operation, and an operation part of the handle is arranged in the concave cavity. The method is easy to reduce project cost, simplify equipment, improve the sharing degree of modules or equipment, and is suitable for upgrading and reconstruction of old equipment. The switch is small in occupied space, high in integration level and high in reliability on the premise that a newly-added module is included.

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 wide variety of modules. Peripheral devices such as backpack switches and LTUs are derived. The increase of equipment...

Problems solved by technology

[0004] The addition of new modules makes the internal structure of the switch too compact, the heat dissipation effect of conduction and convection decreases, and the temperature rise of the product cannot meet the requirements of the corresponding standards
