Description

Technical Field

[0001] The present invention relates to the technical field of partial discharge sensor equipment, and in particular to partial discharge intelligent sensor equipment. Background Art

[0002] The partial discharge intelligent sensor device is an online monitoring device installed on the primary switchgear such as the ring network switch cabinet, cable branch box, box transformer, etc. in the distribution network system. It is used to monitor partial discharge online, indicate short circuit and grounding fault of the corresponding cable section, and real-time temperature.

[0003] A currently generally recognized and widely used method for testing partial discharge is the pulse current method. The result is the apparent discharge in pC, which is a quantitative measurement that can objectively reflect the insulation status of electrical equipment.

[0004] Most of the partial discharge sensing devices of the pulse current method detect the discharge point through the Rogowski coil. When partial discharge occurs inside the switch cabinet, high-frequency pulse current will be generated. When these pulse currents pass through the cable shield or high-voltage conductor, they will generate a changing magnetic field around them. The Rogowski coil generates an induced electromotive force at both ends of the coil by inducing these changing magnetic fields.

[0005] However, in the prior art, since the partial discharge sensing devices are mostly fixed at a certain position outside the switch cabinet and are mostly fixedly connected, when partial discharge occurs inside the switch cabinet, they only have the function of detecting the existence of partial discharge in the switch cabinet, but cannot determine the location of the discharge.

DETAILED DESCRIPTION

[0037] Below, the invention is further described in conjunction with the accompanying drawings and specific embodiments:

[0038] Example:

[0039] Reference Figure 1-Figure 8 The partial discharge intelligent sensing device disclosed in the present invention comprises a longitudinal translation bracket 1, a transverse translation bracket 2 and a sensor housing 3, a control panel 4 is fixedly arranged on one side of the sensor housing 3, a mounting bracket 5 is arranged inside the sensor housing 3, and a cooperative structure 6 is arranged at the upper end of the sensor housing 3;

[0040] The longitudinal translation bracket 1 includes a bottom plate 101, a guide shaft 102 and a top plate 103. The four corners of the bottom plate 101 are provided with guide shafts 102. The top ends of the four guide shafts 102 are commonly connected to the top plate 103. A guide groove 104 is provided at the upper end of the bottom plate 101. A positioning bracket 105 is provided inside the guide groove 104. A first motor 106 is provided at the top end of the positioning bracket 105. A lateral driving structure 107 is provided on the side of the bottom plate 101.

[0041] The lateral translation bracket 2 includes a rectangular frame 201, connecting rods 202 are provided at both ends of the side walls of the rectangular frame 201, and a first guide rail 203 is provided at one end of the connecting rod 202 away from the rectangular frame 201. Sliding grooves 204 are provided on the two long side walls inside the rectangular frame 201, and connecting sliders 205 are provided inside the sliding grooves 204. The two connecting sliders 205 are respectively fixedly connected to the two end walls of the control panel 4, and connecting holes 206 for installing the guide shaft 102 are provided at both ends of the rectangular frame 201 and the first guide rail 203.

[0042] Both side walls of the sensor housing 3 are provided with mounting grooves 7, and a connecting plate is arranged inside the mounting groove 7. The end of the connecting plate away from the control panel 4 is commonly connected to a positioning slider 8 inserted into the first guide rail 203. The first screw rod 9 and the positioning rod 10 are respectively arranged at both ends of one side of the connecting plate. A limiting guide rail 11 is arranged on the side wall of the positioning rod 10. The first screw rod 9 is fixedly connected to the motor shaft of the first motor 106, and the positioning rod 10 is rotatably connected to the top end of the positioning bracket 105.

[0043] In this embodiment, when there is partial discharge inside the switch cabinet, the first motor 106 drives the first screw rod 9 to rotate, so that the connecting plate moves upward, and the transverse drive structure 107 does not work at this time, and then the sensor housing 3 only moves upward, and the detection coil 507 is inside the sensor housing 3, and the detection coil 507 is relatively fixed to the sensor housing 3, so the movement trajectory of the detection coil 507 is the same as the movement trajectory of the sensor housing 3, and when the current at the partial discharge point remains unchanged, when the detection coil 507 gradually approaches the partial discharge point, the current position signal detected by the detection coil 507 will gradually increase;

[0044] When detecting partial discharge, the sensor housing 3 is first moved upward, and the detection coil 507 inside the sensor housing 3 is checked to see whether there is a change in the intensity of the induced electromotive force, so as to determine the direction of the current flow at the partial discharge location.

[0045] Specifically, during the upward movement of the sensor housing 3, if the intensity of the induced electromotive force does not change, the relative position of the detection coil 507 and the direction of the current flow at the partial discharge point remains unchanged, so the current flow direction at the partial discharge point is the same as the direction of movement of the sensor housing 3. At this time, the sensor housing 3 is stopped in this straight line direction, and the sensor housing 3 is moved laterally through the lateral driving structure 107. At this time, the sensor housing 3 will change its position with the partial discharge point during the lateral movement. The position where the induced electromotive force is the maximum in this trajectory is the position where the detection coil 507 is closest to the partial discharge point, thereby achieving the effect of determining the partial discharge point.

[0046] On the contrary, when the sensor housing 3 moves upward, if the intensity of the induced electromotive force changes, the sensor housing 3 is stopped at the position where the induced electromotive force intensity is the highest, and when the sensor housing 3 is moved horizontally, if the intensity of the induced electromotive force does not change, the partial discharge is located on this horizontal trajectory;

[0047] In summary, the purpose of determining the location of the partial discharge can be achieved by moving the sensor housing 3, thereby facilitating the maintenance of the switch cabinet.

[0049] In this embodiment, the mounting protrusion 12 is provided to fix the mounting bracket 5, and the air inside the sensor housing 3 flows through the two ventilation holes 13 and the cooling fan 14, so as to prevent the device from overheating.

[0055] In this embodiment, the rotating plate 1601 and the detection coil 507 are fixed by the setting of the coil clamp 1603, so that the purpose of controlling the rotation of the detection coil 507 and adjusting the axis of the detection coil 507 can be achieved through the rotation of the rotating plate 1601. The external thread ring 1602 is used to thread the rotating plate 1601 into the inside of the mounting hole.

[0056] In a further preferred embodiment of the present invention, Figure 1-8 As shown, the cooperative structure 6 includes a mounting plate 601, and the mounting plate 601 is fixedly mounted on the top of the sensor housing 3.
