The utility model discloses compare in traditional relay protection cabinet, increased convenient driving tool, be connected to the relay contact of installation on the qualified vertical drawer of inspection with the chuck of device, install vertical drawer (behind the connecting device) and install back relay protection cabinet, normally connect the secondary line, only need the chuck of short circuit device lead-out wire during the transmission draw forth the point (be equal to the contact of short circuit relay), can accomplish protection transmission work.
Description
Technical Field
The utility model belongs to the technical field of relay protection device, in particular to relay protection device cabinet with convenient driving tool.
Background
The relay of the Russian relay protection device is installed in a metal frame (for short, a vertical drawer) similar to a drawer (generally vertical), and when the Russian relay protection device operates normally, the drawer is placed back into the relay protection cabinet to be connected with a secondary cable. The performance and technical parameters of the relay arranged on the drawer need to be regularly checked, so that the performance of the relay is qualified during the use period, and the use requirement of a user is met.
Original installation transmission means
The vertical drawer provided with the relay needs to be taken out periodically, sent to a laboratory for internal relay check, taken back to the site after being qualified, the vertical drawer is placed outside the device cabinet (short-circuit relay contacts cannot be carried out in the installation and return device) and connected with a secondary line, protection and control loop transmission are carried out by using a short-circuit protection relay contact mode, and the reliability of the loop and the reliability of the relay are verified. And after the transmission is qualified, the secondary cable is disconnected, and then the vertical drawer is installed to the relay protection cabinet. And the secondary loop is disconnected in the installation process, so that the switching-on and switching-off transmission is carried out again for verifying the complete usability of the protection and control loop.
After the protection is verified to be qualified, the vertical drawer cannot be installed back to the relay protection cabinet in order to manually short-circuit the contact (wiring terminal) of the protection relay, but needs to be connected with a secondary line; and after the transmission is qualified, the secondary line is disconnected, the vertical drawer is installed back to the relay protection cabinet, and the secondary line is disconnected in the installation process, so that the primary transmission needs to be carried out on the closing and opening loop. The process is complicated, and 2 times of transmission and 2 times of connection (disconnection) of the secondary line are required. Namely: the protection test requires 2 transmissions. The secondary line needs to be connected, disconnected and reconnected repeatedly.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a relay protection device cabinet with convenient driving tool to solve above-mentioned problem.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a relay protection device cabinet with a convenient transmission tool comprises a vertical drawer, a relay, a binding post, a chuck controller and a chuck leading-out point; the relay is arranged on the relay vertical drawer, and the wiring terminal is arranged on the relay; one end of the chuck controller is clamped on the binding post, and the other end is provided with a chuck leading-out point.
Furthermore, the vertical drawer is arranged in the electromechanical protection cabinet in a drawing mode.
Furthermore, the chuck leading-out point is connected with an insulated soft core wire, and the insulated soft core wire is connected with a leading-out chuck.
Furthermore, the lead-out chuck is wrapped with an insulating wrap.
Compared with the prior art, the utility model discloses there is following technological effect:
the utility model discloses compare in traditional relay protection cabinet, increased convenient driving tool, be connected to the relay contact of installation on the qualified vertical drawer of inspection with the chuck of device, install vertical drawer (behind the connecting device) and install back relay protection cabinet, normally connect the secondary line, only need the chuck of short circuit device lead-out wire during the transmission draw forth the point (be equal to the contact of short circuit relay), can accomplish protection transmission work.
The control power supply of the relay protection cabinet is disconnected, and the chuck controller is pinched, so that the chuck connected with the relay can be loosened; the device can be slowly drawn out of the relay protection cabinet, and all work is finished. The relay contact is led out by using a transmission tool, and the chuck is externally controlled to be loosened after transmission is finished, so that the vertical drawer does not need to be mounted (dismounted) for the second time.

FIG. 2 is the structure diagram of the relay protection device cabinet of the present invention
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
a relay protection device cabinet with a convenient transmission tool comprises a vertical drawer 2, a relay 3, a binding post 4, a chuck controller 5 and a chuck leading-out point 6; the relay 3 is arranged on the relay vertical drawer 2, and the wiring terminal 4 is arranged on the relay 3; one end of the chuck controller 5 is clamped on the binding post 4, and the other end is provided with a chuck leading-out point 6.
The vertical drawer 2 is arranged in the electromechanical protection cabinet in a drawing mode.
The chuck leading-out point 6 is connected with an insulated soft core wire 7, and the insulated soft core wire 7 is connected with a leading-out chuck 8.
The extraction chuck 8 is wrapped with an insulating wrapping 9.
Fig. 1 shows the detailed structure of the present invention, including the manual chuck controller, chuck leading-out points, insulated soft core wires, chuck and insulated package. During the use, be connected to the relay contact of installation on the qualified vertical drawer of inspection with the chuck of device, install the relay protection cabinet of installation back (after the connecting device), normally connect the secondary line, only need during the transmission short circuit device lead-out wire the chuck draw-off point (be equal to the contact of short circuit relay), can accomplish protection transmission work.
The control power supply of the relay protection cabinet is disconnected, and the chuck controller is pinched, so that the chuck connected with the relay can be loosened; the device can be slowly drawn out of the relay protection cabinet, and all work is finished.
The key point is that a transmission tool is used for leading out a relay contact, after transmission is finished, the chuck is controlled to be loosened externally, and secondary installation (disassembly) of the vertical drawer is not needed.
