Air switch trip monitoring system

technical field

The utility model relates to an air switch trip monitoring system, which is used for monitoring the trip of an air switch in an electric machine room.

Background technique

For the existing power room, in order to ensure safe production, it is necessary to manually check whether the power equipment is working normally, and report and deal with it in time when the air switch is found to be tripped. In this case, it is necessary for inspectors to discover the tripping condition of the air switch in time, and there are usually many air switches installed in the power room, which requires an increase in the number of inspections and the work intensity of the inspection, which not only consumes labor costs but also often leads to the discovery of air switch tripping Lag problem.

Wherein, the auxiliary contact is used to detect and send the position information of the air switch;

The acquisition device communicates with the auxiliary contact, and is used to receive the position information of the air switch, judge whether the air switch trips according to the position information, and send an alarm to the air switch when it is judged that the air switch trips The device sends an alarm signal and sends air switch tripping information to the monitoring host;

The alarm device is communicatively connected with the acquisition device, and is used for alarming when the alarm signal is received;

The monitoring host is communicatively connected with the acquisition device, and is used for recording and displaying the air switch trip information when receiving the air switch trip information.

Preferably, said auxiliary contact is a position sensor.

Preferably, the acquisition device is an industrial computer or a single-chip microcomputer.

Preferably, the warning device is a warning light and/or a loudspeaker.

Preferably, the monitoring host includes a memory for storing trip information of the air switch.

The air switch trip monitoring system provided by the utility model can automatically detect whether the air switch trips, and can alarm when the air switch trips, and record and display relevant information at the same time, so that the staff can find the air switch trip in time and carry out corresponding processing.

Description of drawings

Fig. 1 is a schematic structural diagram of an air switch trip monitoring system according to an embodiment of the present invention.

Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the utility model.

Fig. 1 is the structure schematic diagram of the air switch trip monitoring system of the utility model embodiment, as shown in Fig. The host 104, wherein the number of auxiliary contacts 101 is determined according to the number of air switches, that is, each air switch is equipped with an auxiliary contact 101, and all auxiliary contacts 101 are connected to the acquisition device 102 through cables.

Among them, the auxiliary contact 101 is used to detect and send the position information of the air switch; the acquisition device 102 is communicatively connected with the auxiliary contact 101, used to receive the position information of the air switch, and judge whether the air switch trips according to the position information. When tripping, send an alarm signal to the alarm device 103 and send the air switch tripping information to the monitoring host 104; the alarm device 103 is connected with the acquisition device in communication, and is used for reporting to the police when receiving the alarm signal; the monitoring host 104 is communicated with the acquisition device 102, And it is used to record and display the air switch trip information when receiving the air switch trip information.

Wherein, the auxiliary contact 101 is preferably a position sensor; the acquisition device 102 is preferably an industrial computer or a single-chip microcomputer; the alarm device 103 is preferably a warning light and/or a loudspeaker; the monitoring host 104 preferably includes a memory for storing air switch tripping information.

A general air switch has a moving contact and a static contact inside. When the air switch is closed, the moving contact and the static contact contact each other. When the moving contact moves and separates from the static contact, the air switch trips. In use, for example, the position sensor can be used as the auxiliary contact 101, the transmitting part of the position sensor is set on the moving contact of the air switch, and the receiving part of the position sensor is set on other parts such as the shell of the air switch. The movement of the moving contact causes the air switch to trip when the receiving part of the position sensor receives the signal sent by the transmitting part and sends the position information of the air switch to the acquisition device 102 . For example, the closing of the air switch can be represented by a digital signal 0, and the tripping of the air switch can be represented by a digital signal 1. When the acquisition device 102 detects that the signal of the auxiliary contact 101 changes from 0 to 1, it can send a signal to the alarm device 103 so that the alarm lamp of the alarm device 103 lights up or flashes, or makes the speaker sound. At the same time, the acquisition device 102 sends a signal to the air switch to trip After receiving the air switch trip information sent by the acquisition device 102, the monitoring host 104 displays the air switch trip information on the display and stores the air switch trip information in the memory. In this way, the on-site staff will receive a prompt from the alarm device 103, and the remote staff will receive a prompt from the monitoring host 104, so as to perform corresponding processing in time.

The above embodiments are only exemplary embodiments of the utility model, and are not used to limit the utility model, and the protection scope of the utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the utility model within the spirit and protection scope of the utility model, and such modifications or equivalent replacements should also be deemed to fall within the protection scope of the utility model.
