Description

GIS local on-line monitoring sensor installation bracket

technical field

The invention relates to a sensor installation bracket, in particular to a GIS local on-line monitoring sensor installation bracket.

Background technique

In recent years, GIS equipment (referring to gas-insulated fully enclosed combined electrical appliances, also called gas-insulated switchgear) has been more and more used in power systems because of its beautiful appearance, small footprint, less faults, and reliable operation. At present, the installation method of the external sensors of the matching GIS online monitoring system adopts springs, angle irons and other devices to be installed on the outside of the equipment as a whole, which has the following disadvantages:

(1) The installation is simple and uncoordinated with the simple appearance of the overall equipment;

(2) Barely installed, there are certain accident safety hazards;

(3) The installation and disassembly of the sensor itself is inconvenient;

(4) It must be installed before the GIS equipment is inflated, or the GIS flange connection bolts are required to have enough length for the installation fixture, and the installation is not flexible;

Therefore, the installation of the GIS online monitoring system sensor requires a simple structure, flexible installation, convenient and practical, safe and reliable installation device.

Contents of the invention

The object of the present invention is to provide a GIS online monitoring system sensor mounting bracket, which has a simple structure, flexible installation, convenience and practicality, and high safety and reliability.

To achieve the above object, the present invention is achieved through the following technical solutions:

The installation bracket of the GIS local on-line monitoring sensor is characterized in that it includes an end cover, a base, a side plate, and a spring. The base is a geometric whole with a cylindrical body in the center of the upper part of a cuboid. The middle part is a through hole. The upper part of the base is provided with an end cover and Threads are used for matching connection, springs are arranged inside the end cover, and side plates are arranged on both sides of the base.

The base and the side plates are connected by bolts.

One side of the base is provided with a reserved hole.

The side plate is arc-shaped, and is provided with flange bolt holes and jack screw bolts matched with the flange bolts, and the upper part is provided with grooves matched with the reserved holes of the base.

The material of the end cover, the base and the side plate is high-strength aluminum alloy whose surface has been oxidized.

The spring material is stainless steel.

Compared with prior art, the advantage of the present invention is:

The device (1) has a simple structure, is easy to manufacture, has a short production cycle, and can be produced in series; (2) is flexible in installation, and can be installed after the overall GIS equipment is inflated, and is not limited by the installation environment; (3) is convenient and practical, only The sensor needs to be put into the inner cavity of the base, and no other tools are needed to complete the installation of the sensor; the reserved hole in the base also provides convenience for the wired transmission sensor; The side plate is tightened to fix the mounting bracket on both sides of the flange, and it can also be adjusted appropriately through the side plate and base connecting bolts to adapt to pot insulators of different thicknesses; the spring realizes the effective contact between the sensor probe and the pot insulator and protects the sensor from rigidity. extrusion; improves overall device reliability.

Detailed ways

The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

See Fig. 1, Fig. 2, Fig. 3, the installation bracket of GIS local on-line monitoring sensor, including end cover 1, base 3, side plate 5, spring 2, the base 3 is a geometric whole with a cylinder in the center of the upper part of the cuboid, and the middle part is Through holes, the upper part of the base 3 is provided with an end cover 1 and is connected by a screw thread 10, the end cover 1 is provided with a spring 2, the two sides of the base 3 are provided with side plates 5, and the base 3 and the side plates 5 are connected by Bolt 14 connection, base 3 side is provided with base reserved hole 12, side plate 5 is arc-shaped, is provided with flange bolt hole 16 that matches with flange bolt 7, top screw bolt 6, and the upper part is provided with base The side plate groove 15 matched with the reserved hole 12, the end cover 1, the base 3, and the side plate 5 are made of high-strength aluminum alloy, and the material of the spring 2 is stainless steel.

In the embodiment, one side of the base 3 is first connected to the side plate 5 with the connecting bolt 14, and the flange bolt hole 16 of the side plate 5 connected to the base 3 is passed through the flange bolt 7; then the sensor 4 is placed on the base 3 The inner cavity of the inner cavity, so that the sensor 4 is arranged on the upper part of the pot insulator 8; then pass the flange bolt hole 16 of the other side plate 5 through the flange bolt 7 of the other side, and connect the base 3 with the connecting bolt 14, and then tighten the two Screw the top screw bolt 6 of the side plate 5 to fix the base 3 and the side plate 5 on the flanges 9 on both sides of the pot insulator 8; finally buckle the end cover 1 with the spring 2 on the base 3, and tighten the screw thread The buckle 10 and the spring 2 not only protect the sensor 4 from hard extrusion but also make the sensor 4 effectively contact with the pot insulator 8, thus completing the installation of the GIS local on-line monitoring sensor 4.

If there is a need to replace the sensor 4, just unscrew the screw thread 10 of the end cover 1 and take out the sensor 4; since the jacking screw 6 is on the flange 9 instead of being connected with the flange 9, the device It can be installed before and after the overall GIS equipment is inflated, and there is no safety hazard such as air leakage; the device is made of non-magnetic materials, which effectively avoids defects such as heating due to eddy current loss and hysteresis loss; if the sensor 4 is wired transmission In this way, the transmission cable can be directly connected to the sensor cable interface 11 through the corresponding side plate groove 15 and the base reserved hole 12, which provides convenient conditions for the wired transmission of the sensor 4.
