However, with the continuous development of the power system and the continuous growth of power load, the high-voltage disconnectors may become abnormal in the long-term operation due to aging, mechanical wear, electrical failure and other factors, thus affecting the stability and safety of the power grid. Therefore, it is necessary to monitor the opening and closing status of the high-voltage disconnectors.

[0004] Although this patent can provide feedback on the temperature between the switch blade and the switch seat, it cannot monitor the closing state of the high-voltage disconnector, nor can it monitor the pressure of the galvanized steel sheet after closing, nor can it monitor whether the galvanized steel sheet is loose. Utility Model Content

[0005] The utility model aims to provide a device for monitoring the opening and closing status of a high-voltage disconnector, which solves the problem that the existing online monitoring device for disconnectors cannot monitor the closing status of the high-voltage disconnectors, cannot monitor the pressure of the galvanized steel sheets after closing, and cannot monitor whether the galvanized steel sheets are loose.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a high-voltage disconnector opening and closing state monitoring device, including a base, a plurality of groups of supporting porcelain bottles one and supporting porcelain bottles two are arranged on the top of the base, a galvanized steel sheet is hinged on the top of the supporting porcelain bottle one, a transmission structure is arranged on the side wall of the base, the transmission structure is hinged with the galvanized steel sheet, a contact strip is arranged at one end of the galvanized steel sheet, a mounting plate is bolted to the top of the supporting porcelain bottle two, a static contact is arranged on the top of the mounting plate, an opening and closing monitoring mechanism is arranged on the side wall of the mounting plate, and a pressure monitoring mechanism is arranged on one side of the opening and closing monitoring mechanism;

[0007] The opening and closing monitoring mechanism includes a mounting bar, a mounting box, a laser transmitter and a laser signal receiver. The two mounting bars are fixedly connected to the two ends of the mounting plate, the mounting box is fixedly connected to the top of the mounting bar, the laser transmitter and the laser signal receiver are respectively arranged inside the two mounting boxes, and the laser transmitter and the laser signal receiver are used in combination.

[0008] The above technical scheme is adopted, by setting a base, a supporting porcelain bottle one, a supporting porcelain bottle two, a galvanized steel sheet, a transmission structure, a contact strip, a mounting plate, a static contact, an opening and closing monitoring mechanism and a pressure monitoring mechanism. When in use, the transmission structure can drive the galvanized steel sheet to hinge movement, and can drive the contact strip at one end of the galvanized steel sheet and the static contact to open and close. The opening and closing monitoring mechanism can monitor the opening and closing state of the galvanized steel sheet in real time, which can facilitate the operator to understand the closing state of the high-voltage switch in real time. The pressure monitoring mechanism can monitor the pressure of the galvanized steel sheet, and can monitor the pressure state of the contact strip at one end of the galvanized steel sheet when it contacts the static contact, so that it can be understood in real time whether there is any looseness between the contact strip and the static contact.

[0009] By setting up the installation strip, the installation box, the laser transmitter and the laser signal receiver, when in use, the laser transmitter transmits the laser signal to the laser signal receiver for a long time. When the galvanized steel sheet is closed, the galvanized steel sheet blocks the laser source of the laser transmitter. At this time, the laser signal receiver cannot receive the laser signal. At this time, it can be known that the galvanized steel sheet is in a closed state. When the galvanized steel sheet is opened, the laser signal receiver receives the laser signal again. This process can monitor the closing state of the high-voltage disconnector in real time.

[0011] By adopting the above technical solution, a connecting frame, a T-shaped rod, a support spring, a mounting frame, an insulating rod, a pressure rod, a mounting block and a pressure sensor are set. When in use, when the galvanized steel sheet is in the process of closing, the galvanized steel sheet presses down the insulating rod. At this time, the mounting frame squeezes the support spring downward. At the same time, the pressure rod squeezes the pressure sensor during the downward movement of the mounting frame. The pressure value of the pressure sensor can be used to understand the pressure after the galvanized steel sheet is closed, and it can be understood whether there is any looseness between the contact strip and the static contact.

[0012] Furthermore: two guide covers are fixedly connected to the top of the connecting frame, and the guide covers are movably connected to the mounting frame.

[0014] Furthermore: an adjustment block is fixedly connected to the top of the guide cover, an adjustment screw is threadedly connected to the middle of the adjustment block, an adjustment slot is opened in the middle of the guide cover, and pressure blocks movably connected to the adjustment slot are fixedly connected to both ends of the mounting frame, and the bottom of the adjustment screw is in contact with the pressure block.

[0015] By adopting the above technical solution, an adjusting block, an adjusting screw, an adjusting slot and a pressure block are set. When in use, the adjusting screw is rotated to move the adjusting block thread, and the adjusting screw is pressed downward to cause the pressure block to move up and down inside the adjusting slot. This process can adjust the gap between the mounting frame and the connecting frame, and can flexibly adjust the supporting force of the supporting spring to prevent the insulating rod from supporting the galvanized steel sheet too much.

[0016] Furthermore: a ceramic tube is sleeved on the side wall of the insulating rod, and the ceramic tube is movably connected to the insulating rod.

[0017] By adopting the above technical solution, the insulating rod can be protected by arranging a ceramic tube, and the ceramic tube has the effects of high insulation and low dielectric constant.

[0018] Further: transparent glass is provided on the side wall of the installation box.

[0019] By adopting the above technical solution and arranging transparent glass, the laser transmitter and laser signal receiver inside the installation box can be protected.

[0020] Furthermore: a protective top is fixedly connected to the top of the installation box.

[0021] By adopting the above technical solution and providing a protective roof, it is possible to prevent rainwater from splashing into the interior of the installation box, and the installation box can be protected from rain.

[0022] In summary, the utility model has the following beneficial effects:

[0023] By setting up an opening and closing monitoring mechanism, the opening and closing status of the galvanized steel sheet can be monitored in real time, which can facilitate the operator to understand the closing status of the high-voltage switch in real time.
