Abstract

The invention discloses a visible alarm device for a draw-out high voltage switch cabinet, belonging to the technical field of high voltage supporting equipment. The visible alarm device mainly solves the problem that mechanical or electric faults are easily caused by some existing invisible operation processes. The visible alarm device is mainly characterized by comprising a display, a micro camera, a temperature sensor, an arc light sensor, a control unit and a power module; the control unit is a control circuit composed of a processor, a peripheral circuit, a visible doorbell circuit, a drive circuit, an alarm and trip circuit and an analog-digital conversion circuit; the display, the micro camera, the temperature sensor and the arc light sensor are respectively connected with the processor, and the two input ports of the analog-digital conversion circuit are respectively an arc light signal input end and a temperature signal input end. The visible alarm device has the characteristics that the push-in process of a draw-out circuit breaker is visible and the indoor temperature of the circuit breaker and the arc light of a bus room can be detected and alarmed.

Description

technical field [0001] The invention belongs to the technical field of high-voltage complete sets of equipment, and in particular relates to a visual alarm device for improving the safe operation of a withdrawable high-voltage switchgear and avoiding damage to a circuit breaker or switchgear. Background technique [0002] With the rapid development of economic construction, outdated cabinet types such as GG1A and XGN2-12 have been rapidly eliminated for power transmission and distribution equipment, and the relatively safe and reliable KYN type is used as its replacement product. When we enjoy the more reliable, safer and more compact advantages brought by the KYN switchgear, we also notice that due to the particularity of the operation of this type of switchgear, some processes in the operation process are invisible. If the sliding mechanism of the static contact valve in the cabinet is faulty or out of order, it is very easy to damage the advancing circuit breaker contacts...
