Abstract

The invention provides an air switch state detection device, an air switch and an air switch state detection system. The air switch state detection device comprises an interlock lever, a state detection element, a microgeneration device, a power conditioning memory circuit, a CPU module and a wireless signal transmission module. The microgeneration device converts mechanical energy operating the air switch into electrical energy. The power conditioning memory circuit powers the CPU module and the wireless signal transmission module. The CPU module acquires an air switch state signal output by the state detection element and transmits the signal to a wireless signal receiving module through the wireless signal transmission module. Finally, the wireless signal receiving module transmits the signal to a signal acquisition system. Air switch state detection is realized. The state signal is wirelessly transmitted. The air switch state detection device does not need an additional power supply, which facilitates the transformation construction of air switch state detection and reduces investment.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to an air switch state detection device, an air switch and an air switch state detection system. Background technique [0002] As a kind of auxiliary equipment, the air switch is not only used in a large number in substations, but also related to the normal operation of protection devices and communication network equipment, and its role is very important. [0003] Generally speaking, the state detection of the air switch can be realized through its own auxiliary contact, which is an accessory of the air switch. In practical applications, many air switches do not have auxiliary contacts installed in advance. In order to realize the state detection of the air switch, it is sometimes considered to install auxiliary contacts again. However, usually on the protective screen cabinet of the substation, the air switches are arranged relatively closely, and the auxiliary contact...
