Description

Technical Field

[0001] The present invention relates to the technical field of discharge monitoring, and more specifically to an on-line partial discharge monitoring device. Background Art

[0002] On-line partial discharge monitoring is a technology used to monitor partial discharge phenomena in power equipment. This technology is based on the physical phenomena and electrical signal changes generated during partial discharge. Through specific technical means, the partial discharge situation of power equipment is monitored in real time, so as to achieve the purpose of maintaining and managing power equipment. When a test sample generates partial discharge under the test voltage, a pulse current is generated through a coupling capacitor. The pulse signal is picked up by the input unit, and after low-noise pre-amplification, filtering amplifier selects the required frequency band and main amplification, the discharge pulse is displayed on the elliptical sweep baseline of the oscilloscope screen. At the same time, it is also sent to the pulse peak meter (logarithmic meter) to display its peak value. The time window unit controls the working time of the pulse peak meter within each cycle of the test voltage, and brightens the display on the display screen during this period. The width and position can be changed, further enhancing the anti-interference ability. When on-line partial discharge monitoring is carried out on a switch cabinet, a monitoring device is required.

[0003] In the existing patent, the publication number is CN110687414A, which discloses an on-line partial discharge monitoring device for high-voltage equipment, including a housing, a disassembly and assembly component, a dust removal component and a waterproof component. A cylinder is provided on one side of the housing, and a disassembly and assembly component is provided on one side inside the cylinder. A monitor is provided inside the housing. A dust removal component is provided on one side inside the housing. A hatch is installed on the other side of the housing. A waterproof component is provided at the top of the housing. The present invention realizes the waterproof function of the device by setting a waterproof component. When in use, the waterproof sealant and waterproof O-ring on the inner wall of the housing can be used to waterproof and moisture-proof the device. At the same time, the rain shield inside the placement cylinder at the top of the housing is used to further enhance the waterproof effect. When the rain shield is in use, the electric telescopic rod is extended and retracted, and the rain shield is drawn out from the inside of the placement cylinder and opened under the action of the folding spring, thus completing the rain shielding function.

[0004] However, in the actual application process, since this monitoring device is used for on-line partial discharge monitoring on a switch cabinet, it needs to be installed beside the switch cabinet during use. Therefore, it needs to be quickly and conveniently installed beside the switch cabinet. During installation, the components cannot be directly snapped into the inside of the device, so manual pushing is required, which will affect the installation convenience of the device and also increase the installation difficulty of the staff.

[0057] Working principle: When in use, when the device needs to be installed, insert the positioning strip 300 on the device into the surface of the limiting component, and then tighten the lead screw 306, so that the lead screw 306 drives the slide bar 304 on the slider 305 to move, thereby enabling the clamping block 303 to squeeze the limiting component, so that the limiting component enters the inside of the card slot 302 during the tightening process. Subsequently, the clamping block 303 performs a clamping and positioning operation on it, so that an automatic clamping and positioning operation is performed during the installation process. At the same time, when the conical rod 503 needs to be installed, the piston 502 and the limit card block 504 on the conical rod 503 are inserted into the L-shaped groove 501. Then rotate the limit card block 504, and the surface of the limit card block 504 squeezes the bottom hemispherical part of the return spring 604. When the bottom of the return rod 505 fits with the upper surface of the limit card block 504, the bottom of the return rod 505 coincides with the card slot 302 on the limit card block 504. At the same time, the magnetic attraction ring 506 adsorbs the return rod 505, so that the return rod 505 performs a positioning operation on it;

[0058] When the shielding angle of the rainshield 403 needs to be adjusted, control the electric push rod 400 to shorten. Then the electric push rod 400 drives the connecting plate 402 on the shaft seat 401 to move, so that one end of the rainshield 403 moves downward, thereby adjusting the inclination angle of the rainshield 403;

[0059] When components need to be connected and protected, insert the circuit to be connected into the inside of the connecting tube 600. Then pull the T-shaped rod 601 and then loosen the T-shaped rod 601. The return spring 604 resets the T-shaped rod 601, so that the bottom of the T-shaped rod 601 squeezes the surface of the circuit. When the circuit needs to be protected, extend the circuit into the inside of the wiring tube 703. Then the protection spring 701 resets it, so as to prevent the same part of the circuit from being damaged.
