Description

Disconnecting link state recognition device

Technical Field

The utility model relates to an electric field, concretely relates to switch state identification equipment.

Background

The isolation knife switch is an electric appliance commonly used in a high-voltage power transmission system and used for switching on and off a circuit, and the basic principle and the process of switching on and off are as follows: the control loop operates the motor to rotate, the movable contact of the disconnecting link is driven to rotate through the corresponding transmission mechanism and is connected with or separated from the fixed contact, the disconnecting link is isolated from the switching-on or switching-off, and meanwhile, the auxiliary contact of the disconnecting link outputs a corresponding switching-on or switching-off signal. The working principle and the structure of the device are simple, but the usage amount is large, and the requirement on the working reliability is high.

At present, most state recognition devices judge the switch state of the knife switch through camera image analysis, and the recognition mode has the following defects: the imaging effect is poor at night or in cloudy days.

Disclosure of Invention

The utility model aims at solving the above problem and providing a disconnecting link state identification device.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a switch state recognition device, includes knife switch shell, be equipped with the metal pole in the middle of the knife switch shell, the metal pole outside is connected with the insulator spindle, the insulator spindle outside is connected with the handle, the insulator spindle upper end corresponds the position left end and is equipped with first contact, the insulator spindle upper end corresponds the position right-hand member and is equipped with the second and electrocutes, the insulator spindle lower extreme corresponds the position and is equipped with the third contact, the insulator spindle lower extreme corresponds the position and is equipped with the fourth contact.

The first contact, the second electric shock, the third contact and the fourth contact are completely the same in structure and comprise a pair of bases, a metal block is arranged on one side, opposite to the metal block, of the base, a spring is arranged on one side, opposite to the spring, of the metal block, a fixing block is arranged on one side, opposite to the spring, of the fixing block, the lower end of the fixing block is connected with a battery through a wire, the right end of the battery is connected with a signal transmitter, and an internal isolation shell is arranged on the outer sides of the battery.

And an access door is arranged at the lower end of the inner isolation shell.

Detailed Description

The following examples are presented to enable those skilled in the art to more fully understand the present invention, but are not intended to limit the invention in any way.

As shown in fig. 1-2, a disconnecting link state identification device includes a disconnecting link switch housing 1, a metal rod 4 is disposed in the middle of the disconnecting link switch housing 1, an insulating rod 3 is connected to the outer side of the metal rod 4, a handle 2 is connected to the outer side of the insulating rod 3, a first contact 51 is disposed at the left end of the corresponding position of the upper end of the insulating rod 3, a second contact 52 is disposed at the right end of the corresponding position of the upper end of the insulating rod 3, a third contact 53 is disposed at the corresponding position of the lower end of the insulating rod 3, and a fourth contact 54 is disposed at the corresponding position of the lower end of the insulating rod 3.

The first contact 51, the second contact 52, the third contact 53 and the fourth contact 54 are identical in structure and comprise a pair of bases 61, a metal block 62 is arranged on one side, opposite to the metal block 62, of each base 61, a spring 63 is arranged on one side, opposite to the spring 63, of each spring 64, a battery 68 is connected to the lower end of each fixed block 64 through a lead, the right end of each battery 68 is connected with a signal transmitter 67, an internal isolation shell 65 is arranged on the outer sides of each battery 68 and the signal transmitter 67, and an access door 66 is arranged at the lower end of each internal isolation shell 65.

The utility model discloses the theory of operation as follows:

when the signal received by the remote end is that the first contact 51 and the second contact 52 are connected, and the third contact 53 and the fourth contact 54 are disconnected, the state is normally disconnected.

When the signal received by the remote end is that the first contact 51 and the second contact 52 are opened and the third contact 53 and the fourth contact 54 are closed, the state is normal closed.

When the remote end receives a signal that the first contact 51 and the second contact 52 are connected and the third contact 53 and the fourth contact 54 are connected, the knife switch state needs to be reset for a bad contact state.

When the signals received by the far end are the signals fed back by the first contact 51, the second contact 52, the third contact 53 and the fourth contact 54, the states are abnormal, and the maintenance is required.

Those skilled in the art will appreciate that the above embodiments are merely exemplary embodiments and that various changes, substitutions and alterations can be made without departing from the spirit and scope of the invention.
