[0021] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0022] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0023] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0024] Combination Figure 1 , Figure 6 and Figure 7 As shown, this partial discharge tester for power monitoring includes a device body 1, a wire 2 on the tester body, one end of the wire connected to a handle 3, an insulating sleeve 4 on the handle, one end of the insulating sleeve connected to a hemispherical insulating protective cover 19, a locking sleeve 5 on the outside of the insulating sleeve, the locking sleeve including a first part 501 connected to the handle, a second part 502 rotatably connected to the first part, several protrusions 503 formed on the inner surfaces of both ends of the first and second parts, a groove 301 on the handle for inserting into the protrusions, several raised strips 504 formed on the inner surfaces of the middle section of the first and second parts, a slot 302 on the handle for inserting into the raised strips, a probe 6 connected to one end of the handle, and the probe connected to the wire.

[0025] The operator holds the handle and moves the probe to the equipment to be tested. The probe performs the test, and the test signal is transmitted to the equipment body through a wire. While the operator is performing the test, the insulating sleeve on the handle and the hemispherical insulating protective cover connected to one end of the insulating sleeve effectively perform their insulation function, protecting the operator from electric shock and preventing accidental contact with the tested equipment, thus avoiding personal injury.

[0026] In addition, combined Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, the first and second parts are semi-cylindrical and rotatably connected by a pivot or hinge. The first part is fixed to the handle, and there is a gap between the first and second parts and the handle for the insulating sleeve to pass through. The insulating sleeve has a through hole. The protrusions and ridges on the inner surfaces of the first and second parts pass through the through hole in the insulating sleeve and are inserted into the groove or slot on the handle. The ridges are arc-shaped. One side of the first part is folded outward to form an extension plate 505, and one side of the second part is folded outward to form an extension plate 506. The extension plate 506 has several screw holes, and the extension plate 507 has threaded grooves 507 corresponding to the screw holes. Screws 7 are inserted into the screw holes, and one end of the screw is screwed into the threaded groove. In this embodiment, the insulating sleeve is fitted onto the handle, and the insulating sleeve is also disposed between the locking sleeve and the handle. The locking sleeve and the handle are also provided with a protrusion and groove, and a protrusion and slot insertion and mating structure. The locking sleeve, the insulating sleeve and the handle form an integrated connection mechanism. The extension plate one and extension plate two on the locking sleeve are connected by a screw and screw hole locking structure, so that the locking sleeve can stably fix the insulating sleeve on the handle.

[0027] In addition, combined Figure 2 , Figure 4 and Figure 5 As shown, extension plates one and two have grooves 509 parallel to their length on their sides. The partial discharge tester for power monitoring also includes a strip cover 8 with openings at both ends. The strip cover covers extension plates one and two, and the inner side of the strip cover has a slide rail 801 that slides with the groove. The strip cover has end plates 9 at both ends, and several elastic blocks 10 on one side of the end plates. The strip cover has slots 802 that engage with the elastic blocks. The strip cover is connected to extension plates one and two through a slide rail and groove structure. The strip cover covers extension plates one and two to protect the screw and screw hole locking structure, preventing corrosion of the screw and screw hole locking structure due to rainwater erosion, which could cause the connection between the first and second parts to loosen and affect the locking effect of the locking sleeve on the insulating sleeve. The elastic blocks on the end plates engage with the slots at both ends of the strip cover, allowing the end plates to be easily assembled with or removed from the ends of the strip cover. By removing the end plates from both ends of the strip cover, the strip cover can be easily installed on extension plate one and extension plate two, or removed from extension plate one and extension plate two. The installation and removal of the strip cover and end plates are relatively convenient, providing ease of use for operators.

[0028] Combination Figure 8 and Figure 9As shown, in a preferred structure, the device body has a fixing plate 12 on one side. The fixing plate has a slot 121 parallel to its length direction, and several strip holes 122 parallel to its length direction. A plate 13 is inserted into the slot, and several strip plates 14 are fixed to the plate. A connecting post 15 is fixed to the strip plate, with one end of the connecting post passing through the strip hole and connecting to a suction cup 16. A compression spring 17, which abuts against the plate, is fixed to the bottom of the slot. A hanging groove 131 is opened at one end of the plate, and a hanging ring 18 that mates with the hanging groove is connected to the fixing plate. The suction cup on the plate allows the operator to attach the device body to surrounding equipment using the suction cup, facilitating testing. After the insert plate is inserted into the insert plate slot on the fixing plate, the compression spring in the insert plate slot abuts against the insert plate. At this time, the hanging ring on the fixing plate is hung in the hanging slot on the insert plate. The hanging ring and the compression spring exert force on the insert plate at the same time, so that the insert plate is stably inserted into the insert plate slot.

[0029] In summary, this utility model provides a partial discharge tester for power monitoring. When the operator holds the handle for testing, the insulating sleeve and hemispherical insulating protective cover at the handle prevent the operator from accidentally contacting the tested equipment, ensuring good safety. The handle also features a locking sleeve that fits over the insulating sleeve. The inner surfaces of the first and second parts of the locking sleeve have protrusions and strips that pass through the insulating sleeve and engage with grooves or slots on the handle. Extension plates one on the first part and two on the second part are fixed by screws and threaded grooves. The locking sleeve effectively secures the insulating sleeve to the handle, preventing slippage and improving its reliability against electric shock. A suction cup is attached to a fixing plate on one side of the device body. When using this partial discharge tester, the operator can use the suction cup to attach the device body to surrounding equipment, facilitating testing operations.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
