Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below by combining the specific drawings.

Referring to fig. 1 and 2, the handcart position double confirmation structure in the handcart type high-voltage switch device shown in the figures comprises a switch cabinet 10 and a handcart 20 installed in the switch cabinet 10, and the installation position of the handcart 20 in the switch cabinet 10 is not different from the prior art, and is not described again.

The present invention is directed to double confirmation of the position of the hand truck, and therefore includes two microswitches 30 (or one or more of them) and a real-time monitoring camera 40 and a data record storage conversion host 50.

Referring to fig. 15 to 18, a metal roller 31 is provided at a touch portion of each micro switch 30, so that the micro switch 30 is conveniently touched.

The two microswitches 30 are mounted in the switchgear cabinet 10 at a hand truck test position or at a hand truck working position, for example on a side panel of the circuit breaker chamber 11 of the switchgear cabinet 10, using an integrated microswitch mounting bracket 60 as shown in fig. 11 to 14.

The integrated microswitch mounting bracket 60 shown in fig. 11 to 14 is an L-shaped plate, and a plurality of waist-shaped holes 61a are arranged on a short side 61 of the L-shaped plate at intervals so as to adjust the mounting position of the integrated microswitch mounting bracket 60 on the side plate of the breaker chamber 11 of the switch cabinet 10. Two sets of mounting holes 62a are formed in the long side 62 to facilitate mounting of the two micro switches 30.

A distance adjustable double confirmation stroke push plate 70 is mounted on the top barrier 21 of the hand truck 20. Referring to fig. 7 to 10, the double confirmation stroke push plate 70 is composed of a push plate 71 and two

mounting plates

72 and 73, the two

push plates

72 and 73 are connected into a whole at 90 °, and a waist-

shaped hole

72a and 73a are respectively formed on the two

mounting plates

72 and 73, so that the position of the double confirmation stroke push plate 70 on the top baffle 21 of the handcart 20 can be conveniently adjusted. The push plate 71 and the push plate 72 are connected into a whole at 90 degrees, and

flanges

71a and 71b are respectively arranged on two opposite side edges of the push plate 71. The push plate 71 is used for touching the metal roller 31 on the micro switch 30.

The real-time monitoring camera 40 shown in fig. 3 to 6 is installed in the breaker chamber 11 of the switchgear 10 and faces the breaker break B phase, specifically: and a mounting bracket 41 in the real-time monitoring camera 40 is fixed well by drilling a hole on a side plate of the breaker chamber 11 at the position opposite to the phase B center of the breaker fracture and threading a screw. The network cable plug of the communication cable of the real-time monitoring camera 40 is connected to the video input network port of the data recording storage conversion host 50, and the power line is connected to the DC12V power port.

The data recording, storing and converting host 50 is installed on a mounting plate in the relay room 12 of the switch cabinet 10, specifically: firstly, 4M 5 screw holes are formed on the mounting plate, and then the data recording, storing and converting host 50 is fixed on the mounting plate of the relay room 12 of the switch cabinet 10 by screws with the thread length of about 8 mm. The motor starting trigger terminal, the DC24V power supply terminal, the shell grounding terminal and the I/O plug terminal are connected.

After all components are installed, the wiring is checked to be completely correct, the DC24V power supply is supplied, the system starts, and the monitoring program is automatically operated when the system is started. The default IP address of the system is 192.168.1.200, the main controller and the computer are directly connected by a network cable, and the IP is set as follows: 192.168.1.2-192.168.1.255 mainly make the main controller and the computer in the same LAN. The VNC remote desktop program is operated, a main controller is logged in, and after normal connection, the desktop of the main controller is displayed in real time through a computer-side VNC software interface.

The working principle of the invention is as follows: when the handcart 20 moves, the double-confirmation-stroke push plate 70 is driven to act, so that the microswitch 30 is touched at the designated handcart test position or working position, and a timely signal is sent to the data recording, storing and converting host 50 and is converted to the background. This is an electrical signal location confirmation; video stream camera confirmation: the operator can directly observe the fracture condition through remote video, so that whether the charged part is in place or not is judged. This is a kind of screen position confirmation.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof.
