Description

Technical Field

[0001] This utility model belongs to the field of sensor mounting structure technology, and particularly relates to a multi-layer array mounting structure for partial discharge sensors. Background Technology

[0002] Partial discharge can be detected by using a multi-layer array of partial discharge sensors to detect the electromagnetic waves generated by partial discharge. This avoids the corona discharge and other periodic interference signals that are difficult to avoid in conventional electrical testing methods, improving the signal-to-noise ratio of partial discharge detection and enhancing its effectiveness. Early solutions used independent sensors placed at several locations near the discharge device or structure for monitoring. However, this was inconvenient to maintain and use, and could only be adapted to single-point, single-discharge scenarios, resulting in low efficiency. Therefore, a multi-layer array detection system is needed for proper installation and operation. Utility Model Content

Detailed Implementation

[0020] The present invention will be described in detail below with reference to specific embodiments.

[0021] This utility model discloses a multi-layer array mounting structure for partial discharge sensors. It provides an installation and detection structure suitable for multi-layer array detection of partial discharge sensors, facilitating the installation of multi-layer sensor arrays in various partial discharge monitoring scenarios in power distribution stations. The structure adopts a hanging installation method and is suitable for the joint detection of partial discharge signals within a 360-degree range below the installation position. It can be used for sensor arrays of various models and specifications.

[0022] like Figure 1 , Figure 2 As shown, its main structure includes a hanger 1, a connecting rod 2, a support frame 3, a sensor mounting panel 4, an upper positioning bolt 5, and a lower positioning bolt 6;

[0023] The hanger 1 includes a top plate 10 and an n-shaped boom 11 located on the upper side of the top plate 10; the top plate 10 has a through hole 10a at its center, and the top horizontal arm of the boom 11 has a first positioning hole 11a.

[0024] Hanger 1 is mainly installed on high-level structures or devices such as pole supports in substations. It is installed and fixed by means of a boom and bolts, and is also the basic support structure of the entire installation structure.

[0025] To avoid self-induction in areas with strong electromagnetic fields, such as substations, the hanger 1, connecting rod 2, support frame 3, and sensor mounting panel 4 are generally made of non-metallic insulating materials.

[0026] The connecting rod 2 is vertically arranged and has threaded connection holes at both ends. The upper end of the connecting rod 2 is inserted into the first positioning hole 11a and fixed by the upper positioning bolt 5; the lower end is inserted into the through hole 10a.

[0027] The main structure of the support frame includes a cylindrical positioning part 30 sleeved on the lower half of the connecting rod 2, two support plates 31 located at the upper and lower ends of the cylindrical positioning part 30, and a vertical mounting plate 32 arranged in a ring array between the two support plates 31.

[0028] A vertically extending panel mounting groove 32a is provided on the outer side of the vertical mounting plate 32, and several sensor mounting panels 4 are installed in the panel mounting groove 32a. A second connecting hole is provided at the center of the support plate 31.

[0029] To facilitate the installation and fixing of the sensor, several mounting screw holes 32b are provided at the bottom of the panel mounting slot 32a.

[0030] After the lower end of the connecting rod 2 passes through the cylindrical positioning part 30, it is locked by the lower positioning bolt 6 in the second connecting hole on the lower support plate surface 31.

[0031] The cylindrical positioning part connects to the overall structure, ensuring the relative position of the horizontal support plate, and is also connected and locked to the connecting rod. By rotating the connecting rod 2, the rotation of the support frame can be adjusted simultaneously, thereby freely setting the orientation of the sensor array.

[0032] For ease of operation, a calibration adjustment hole 2a is provided on the upper side of the connecting rod 2. The direction can be easily adjusted by inserting the operating rod structure into the calibration adjustment hole 2a.

[0033] The bottom of the top plate 10 and the top of the upper support plate 31 are respectively provided with annular positioning parts and annular positioning grooves that can be nested together, with the annular positioning parts and annular positioning grooves centered on the cylindrical positioning part 30.

[0034] Vertical mounting panels arranged in a ring array (usually six, eight or more) can achieve omnidirectional coverage. Through the panel mounting slots on the vertical mounting panels, multi-layer sensor array configurations can be realized, which can be used flexibly and freely to meet various monitoring needs.

[0035] It also includes a cover 7, which includes a top annular plastic part connecting part 70 to a cup-shaped glass cover 71 located at the bottom of the plastic part connecting part 70; the upper side of the plastic part connecting part 70 is provided with a detachable snap-fit ​​structure 700 that can snap onto the edge of the top plate 10.

[0036] The cover 7 can be easily installed and connected to the main structure through the plastic connecting part. The glass cover structure protects and isolates the internal sensor array without affecting the propagation of high-frequency electromagnetic waves, thereby improving the service life of the device and ensuring the monitoring effect.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
