Description

Technical Field

[0001] This utility model relates to the technical field of insulation control devices, specifically an insulation control device for high-voltage switchgear. Background Technology

[0002] Insulation control devices are an important component of electrical systems. The following sections introduce them from different aspects: I. Functions and Applications: Insulation Monitoring Function: Real-time monitoring: Insulation control devices can continuously monitor the insulation condition of electrical equipment. They can accurately measure key parameters such as insulation resistance, leakage current, and dielectric loss, thereby reflecting changes in the performance of insulation materials. For example, in substations, by monitoring the insulation of equipment such as transformers, minute changes in insulation resistance can be detected in a timely manner, allowing for early prediction of potential faults. Fault Warning: When the monitored insulation parameters deviate from the normal range, the device can issue a warning signal, which helps to promptly detect problems such as insulation aging, moisture absorption, and partial discharge. For instance, in industrial production environments, if the insulation control device detects a gradual increase in leakage current in motor equipment, it may indicate that the motor insulation is about to fail.

[0003] Patent publication number "CN219876400U" discloses "a mining insulation control device. The device includes: a housing, a control transformer, and a capacitor; the device also includes: an insulation control component and an insulation structure, the insulation control component is disposed on the insulation structure, the insulation structure is disposed on the housing, the insulation control component is connected to the control transformer and / or capacitor, the insulation structure includes: a mounting plate and a partition plate, the mounting plate and the partition plate are connected to form a receiving groove, and the insulation control component is disposed in the receiving groove. Because the insulation control component is disposed in the receiving groove, the receiving groove can protect the insulation control component, avoiding the influence of the underground coal mine environment on the insulation control component. Furthermore, the insulation control component is spaced apart from the housing, increasing the electrical clearance between the insulation control component and the housing, and lengthening the creepage distance between the fuse and the housing. The receiving control component includes multiple electrical components, solving the problem of easy discharge breakdown between energized components."

[0029] The present application will be further described in detail below through the accompanying drawings and examples.

[0030] Reference Figures 1 to 4 This application provides an insulation control device for high-voltage switchgear, including a switch body 1. The switch body 1 is rectangular in shape, with rounded edges. Adjustment components 2 are fixedly installed at the top and bottom of the switch body 1, respectively. The adjustment components 2 include a fixed frame 21 and a bidirectional threaded rod 22. The fixed frame 21 is fixedly installed at the top and bottom of the switch body 1, respectively. The bidirectional threaded rod 22 is connected to the inner side wall of the fixed frame 21 via bearings. A movable frame 23 is threadedly connected to the side wall of the bidirectional threaded rod 22. A sliding groove 2 is provided on one side of the fixed frame 21. 4. The movable frame 23 and the slide groove 24 are slidably connected. The top of the movable frame 23 is connected to a one-way threaded rod 25 by a thread.

[0031] In this embodiment, firstly, turning the crank handle 29 can drive the movable frame 23 to slide inside the slide groove 24 via the bidirectional threaded rod 22. Then, turning the knob 28 can rotate the unidirectional threaded rod 25, allowing the unidirectional threaded rod 25 to slide inside the slide groove 27 via the movable frame 26. Finally, bolts are used to install the whole assembly with the high-voltage switchgear via the movable frame 26. This part can be adjusted according to the reserved holes, resulting in better versatility.
