Description

Technical Field

[0001] The utility model relates to the technical field of GIS discharge sensors, in particular to a mounting mechanism for a GIS local discharge sensor. Background Art

[0002] GIS is a switchgear used in high-voltage power systems. It is widely used in substations and distribution stations of power systems. In GIS, all major equipment, such as circuit breakers, disconnectors, grounding switches, and transmission lines, are encapsulated in a metal shell filled with high-pressure gas. These high-pressure gases are not only used as electrical insulation media, but also used to extinguish arcs during disconnection.

[0003] After searching, a Chinese patent discloses an easy-to-install GIS partial discharge detection built-in coupling sensor (authorization announcement number CN209148820U), which includes a sensor body, a mounting plate and a substrate for mounting the sensor body and the mounting plate. The mounting plate is installed at both ends of the sensor body, the upper surface of the substrate is provided with a mounting groove, and the bottom of the substrate is fixedly connected with a side plate, the left and right sides of the inner surface of the side plate are provided with bolt holes, the internal threads of the bolt holes are connected with bolts, and the two sides of the substrate are provided with through grooves near the upper side of the side plate, and the bottom of the through groove inner cavity is provided with a horizontal groove. Although the above patent technology can be installed in GIS using a medium, and the installation of the substrate is simple, the substrate can be fixed by bolts passing through the bolt holes, and the sensor can be directly installed in the substrate through the mounting plate mounting groove and the sensor mounting groove, so that the effect of fixing the sensor in the GIS can be achieved;

[0004] However, in the actual application of this patented technology, the above-mentioned device cannot perform buffering and pressure after installing the discharge sensor of GIS. If long-term local discharge is not buffered or controlled, it may cause permanent damage to the equipment, including damage to the insulating materials and electrical equipment inside the GIS. If the GIS system cannot effectively perform buffering and pressure through design and maintenance measures, its insulating parts may face excessive electrical stress, accelerating aging and failure. Utility Model Content

[0005] In view of the above problems existing in the prior art, the main purpose of the utility model is to provide a mounting mechanism for a GIS partial discharge sensor.

[0006] The technical solution of the utility model is as follows: a mounting mechanism for a GIS partial discharge sensor, comprising a base, a support frame and a pressure block, the support frame being arranged above the base, the pressure block being slidably connected to the bottom of the support frame, the top of the pressure block being equidistantly provided with three limit grooves, the top of the inner wall of the support frame being equidistantly fixedly connected with three light rods, the outsides of the light rods being fixedly connected with limit plates, the limit plates being in contact with the tops of the pressure blocks, the bottoms of the light rods being extended to the insides of the corresponding limit grooves, and springs being sleeved on the outsides of the light rods and located between the tops of the inner walls of the support frame and the tops of the limit plates.

[0007] Through the above technical solution, the structural design of the base and the support frame keeps the entire installation mechanism stable, ensuring the safety and stability of the sensor when it is fixed. Three limit grooves are set on the top of the pressure block. These limit grooves are used in conjunction with three light rods fixed on the top of the inner wall of the support frame. The combination of the light rods and the limit grooves can accurately position and fix the sensor, and facilitate vertical buffering. The limit plate combined with the spring provides flexible adjustment space and can effectively buffer the impact, thereby improving the installation accuracy of the sensor and protecting the sensor from damage.

[0008] As a preferred embodiment, one end of the top of the base is fixedly connected to a first fixed plate, a first through slot is opened inside the first fixed plate, a threaded rod is rotatably connected inside the first through slot, an external thread of the threaded rod is connected to a first sliding block, the first sliding block is slidably connected to the first through slot, and one side of the first sliding block is fixedly connected to the outer side of the support frame.

[0009] Through the above technical solution, the design of the first fixing plate and the threaded rod makes the horizontal position of the sensor mounting mechanism adjustable, which is convenient for the user to adjust the sensor position according to needs.

[0010] As a preferred implementation, an adjustment slot is provided on the top of the first fixing plate, and the top of the threaded rod extends into the interior of the adjustment slot and is fixedly connected with an adjustment knob.

[0011] Through the above technical solution, the adjustment knob improves the convenience and accuracy of adjustment, making it easier for users to adjust the position of the support frame and the sensor.

[0012] As a preferred embodiment, a second fixing plate is fixedly connected to the top of the base and one end away from the first fixing plate, a second through slot is defined inside the second fixing plate, and a limiting rod is fixedly connected inside the second through slot.

[0013] Through the above technical solution, the structure of the second fixing plate and the limiting rod can perform fine positioning of the sensor installation mechanism in another direction, providing stable support.

[0014] As a preferred embodiment, the outside of the limiting rod is slidably connected to a second sliding block, the second sliding block is slidably connected to the second through groove, and one side of the second sliding block is fixedly connected to the outer side of the support frame.

[0015] Through the above technical solution, the second sliding block slides outside the limiting rod, so that the lifting and lowering trajectory of the support frame is limited.

[0016] As a preferred embodiment, arc-shaped placement grooves are provided on the top of the base and the bottom of the pressing block.

[0017] Through the above technical solution, the placement groove can ensure good fit when the sensor is installed, thereby increasing the stability of the installation.

[0018] As a preferred implementation, two mounting plates are fixedly connected to both sides of the base.

[0019] Through the above technical solution, the setting of the mounting plate enables the mounting mechanism to be stably fixed in a variety of application environments, ensuring effective monitoring of the sensor.

[0020] Compared with the prior art, the advantages and positive effects of the utility model are:

[0021] In the utility model, the above-mentioned device presses the GIS local discharge sensor through the pressing block. During long-term operation, the pressing block expands outward, so that the compression spring can buffer the GIS local discharge sensor. On the one hand, it can protect the local discharge sensor from the influence of the external environment and ensure the normal operation of the sensor. On the other hand, it provides appropriate protection for the sensor, which can improve the operating reliability of the entire GIS equipment, reduce unnecessary operation and maintenance intervention caused by sensor failure, and greatly improve the operation quality and use efficiency compared with traditional devices.

Three limit grooves 4 are set on the top of the pressure block 3. These limit grooves 4 are used in conjunction with three light rods 5 fixed on the top of the inner wall of the support frame 2. The combination of the light rods 5 and the limit grooves 4 can accurately position and fix the sensor, and conveniently perform vertical buffering. The limit plate 6 combined with the spring 7 provides a flexible adjustment space and can effectively buffer the impact, thereby improving the installation accuracy of the sensor and protecting the sensor from damage.

[0033] Among them, one end of the top of the base 1 is fixedly connected to a first fixed plate 8, a first through groove 9 is opened inside the first fixed plate 8, a threaded rod 10 is rotatably connected inside the first through groove 9, and the external thread of the threaded rod 10 is connected to a first sliding block 13, the first sliding block 13 is slidably connected to the first through groove 9, and one side of the first sliding block 13 is fixedly connected to the outer side of the support frame 2.

[0034] Among them, an adjustment groove 11 is opened at the top of the first fixed plate 8, the top of the threaded rod 10 extends to the inside of the adjustment groove 11 and is fixedly connected with an adjustment knob 12.
