Online monitoring device for lightning arrester

Abstract

The invention discloses an online monitoring device for a lightning arrester. The device comprises a box body, a protection mechanism and a caching mechanism, a box cover is arranged on the surface ofone side of the box body; the protection mechanism comprises a pull ring; the pull ring is positioned on the surface of the other side of the box body; a hinge is fixedly connected to the surface ofone side of the box body, the box cover is movably connected with the box body through the hinge, a locking groove is formed in the front surface of the box body, a locking plate is fixedly connectedto the surface of one side of the box cover, the locking plate is located in the locking groove, and a first clamping groove is formed in the surface of one side of the locking plate; and through thearrangement of the pull ring, the locking groove and the locking plate, the box cover can be closed on one side of the box body in a fastened mode, a power supply assembly inside the device is protected, and the safety and sealing performance of the device are improved. Through the arrangement of the pull rod, the sliding block and the sliding groove, a temporary storage protection plate can be conveniently and rapidly disassembled, the protection effect of the temporary storage protection plate on the power supply assembly on the inner side of the box body is guaranteed, and the shockproof performance of the device is improved.

Description

technical field [0001] The invention belongs to the technical field of monitoring devices, and in particular relates to an online monitoring device for a lightning arrester. Background technique [0002] The surge arrester monitor is an instrument used to detect the internal defect of poor contact between the MOA valve and the electric valve of the gapless zinc oxide arrester for 10kV and below power systems, and to measure the DC reference voltage (U1mA) of the MOA and the leakage current at 0.75U1mA. [0003] However, there are still some disadvantages in the existing on-line monitoring device for lightning arresters. When moving and transporting the device, the box cover is affected by the vibration and opens from one side of the box body, causing damage to the inner power supply components, etc., and when the buffer protection board is long After time use, the surface wears seriously and cannot be replaced. For this reason, we propose an online monitoring device for arre...
