Description

Technical Field

[0001] This invention relates to the field of gas monitoring technology for combined electrical appliances, and more particularly to an installation device for gas monitoring of a sulfur hexafluoride enclosed combined electrical appliance. Background Technology

[0002] Sulfur hexafluoride (SF6) enclosed modular electrical equipment, also known as "gas-insulated switchgear" or GIS for short, includes circuit breakers, disconnectors, grounding switches, voltage transformers, current transformers, surge arresters, busbars, and other equipment. It has advantages such as small size and high voltage rating. Internally, it uses SF6 as the insulating gas. When SF6 leaks, the GIS will experience insulation breakdown, and the SF6 gas can cause asphyxiation. Currently, SF6 and O2 gas content monitors (O2 content decreases when SF6 leaks) are commonly used for GIS chamber leak detection. However, these sensor probes are greatly affected by dust, requiring regular cleaning and adjustment, and are prone to false alarms and missed alarms. Therefore, it is necessary to add GIS chamber pressure sensors to improve device reliability and enable rapid response to faulty chambers. However, existing pressure sensors are difficult to install and remove quickly during use, which is time-consuming and labor-intensive, affecting the device's detection efficiency.

[0031] Example 1

[0032] Reference Figures 1-5 This is the first embodiment of the present invention, which provides an installation device for gas monitoring of a sulfur hexafluoride enclosed combined electrical appliance. The device includes a structural component 100, which includes a structural member 101 and a monitoring member 102 disposed on one side of the structural member 101. The structural member 101 supports the entire device. A clamping component 200 includes an insert 201 disposed on one side of the monitoring member 102, a rotating member 202 disposed inside the structural member 101, and a clamping member 204 disposed inside the structural member 101. The rotating member 202 includes a rotating ring 202a rotatably disposed within a mounting block 101c and an arc-shaped protrusion 202b disposed on the outer surface of the rotating ring 202a. The clamping member 204 includes a fixing ring 204a disposed inside the mounting block 101c. The clamping member 204 also includes a sliding frame 204b slidably disposed outside the fixing ring 204a and an arc-shaped clamping plate 204c disposed on one side of the sliding frame 204b.

[0033] Furthermore, the structural component 101 includes a mounting plate 101a and a bolt 101b threaded onto one side of the mounting plate 101a. The structural component 101 also includes a mounting block 101c disposed on one side of the mounting plate 101a. The monitoring component 102 includes a pressure sensor 102a disposed on one side of the mounting block 101c. The pressure sensor 102a is used to detect the internal pressure of the GIS compartment, which improves the reliability of the device and enables rapid response to faulty gas chambers.

[0034] Preferably, the insert 201 includes an insert cover 201a disposed on one side of the pressure sensor 102a and an insert post 201b disposed on one side of the insert cover 201a. The side wall of the mounting block 101c has a slot, the insert post extends into the slot and is slidably connected thereto, and the size of the insert cover 201a matches the cross-sectional area of ​​the mounting block 101c.

[0035] Specifically, the rotating component 202 includes a rotating ring 202a rotatably disposed within the mounting block 101c and an arc-shaped protrusion 202b disposed on the outer surface of the rotating ring 202a. The rotating component 202 also includes a knob 202d disposed on one side of the rotating ring 202a, with one end of the knob 202d extending out of the mounting plate 101a. When the knob 202d is rotated, it drives the rotating ring 202a to rotate. The rotating component 202 also includes a handle 202e disposed on one side of the knob 202d, which facilitates the rotation of the knob 202d.

[0036] Furthermore, the clamping assembly also includes a clamping member 203 disposed on the outside of the structural member 101. The clamping member 203 includes a mounting bracket 203a disposed on the outside of the mounting block 101c and a rotating shaft 203b rotatably disposed on the side wall of the mounting bracket 203a. The clamping member 203 also includes a top rod 203c slidably disposed on the outside of the mounting block 101c and a clamping block 203d rotatably disposed within the mounting bracket 203a. The rotating shaft 203b allows the clamping block 203d to rotate slightly within the mounting bracket 203a. The other end of the top rod 203c is connected to one side of the clamping block 203d, and the upper side of the clamping block 203d is connected to the insert cover 201. The upper surface of a contacts the clamping block 203. The clamping member 203 also includes a rubber pad 203e disposed on the lower side of the clamping block 203d and a compression spring 203f disposed between the clamping block 203d and the mounting block 101c. The rubber pad 203e can improve the clamping effect of the clamping block 203d. The two ends of the compression spring 203f are distributed and connected to the side wall of the clamping block 203d and the side wall of the mounting block 101c. The compression spring 203f is used to provide the reset force of the clamping block 203d. One end of the push rod 203c extends into the mounting block 101c and contacts the arc-shaped protrusion 202b. The arc-shaped protrusion 202b can squeeze the push rod 203c when rotating.

[0037] In use: After inserting the rod on the lower surface of the pressure sensor 102a into the slot above the mounting block 101c, so that the rod extends into the rotating ring 202a, the cover 201a contacts the upper surface of the mounting block 101c. Then, rotate the knob 202d. The rotation of the knob 202d drives the rotating ring 202a to rotate, causing the arc-shaped protrusion 202b on the outer side of the rotating ring 202a to rotate, pressing the push rod 203c. As a result, the push rod 203c slides outward, pressing the clamping block 203d, causing the clamping block 203d to rotate, thus increasing the pressure. The upper end of the clamping block 203d is pressed into contact with the upper surface of the plug cover 201a to quickly and firmly install the plug cover 201a. During the pressing and fixing process, the rubber pad 203e can enhance the pressing effect of the clamping block 203d. After the installation is completed, the side of the mounting plate 101a with the pressure sensor 102a is inserted into the GIS partition gas chamber. The mounting plate 101a is used to fix the GIS partition gas chamber to the GIS partition gas chamber. Then, the internal pressure of the GIS partition gas chamber is detected to monitor the internal gas.

[0038] Example 2

[0039] Reference Figures 3-8 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: a cavity 202c is formed inside the rotating ring 202a; an annular groove matching the fixed ring 204a is formed on one side of the rotating ring 202a; the fixed ring 204a extends into the cavity 202c through the annular groove; and the fixed ring 204a remains fixed while the rotating ring 202a rotates. The clamping member 204 also includes a sliding frame 204b slidably disposed on the outside of the fixed ring 204a and an arc-shaped clamping plate 204c disposed on one side of the sliding frame 204b. The arc-shaped clamping plate 204c is used to assist in clamping and fixing the insert post 201b. The clamping member 204 also includes a top post 204k disposed on one side of the sliding frame 204b, a spherical top block 204d disposed on one side of the top post 204k, and a shaped block 204e disposed on the inner wall of the rotating ring 202a. The shaped block 204e is used to squeeze the top post 204k during rotation.

[0040] Furthermore, the clamping member 204 also includes an arc-shaped curved surface 204f and an arc-shaped groove 204g. One side of the irregularly shaped block 204e is provided with an arc-shaped curved surface 204f, and the spherical top block 204d contacts the arc-shaped curved surface 204f, so that when the rotating ring 202a rotates, the internal irregularly shaped block 204e rotates accordingly. The movement of the arc-shaped surface compresses the top column 204k, causing the arc-shaped clamping plate 204c on the other side to move. An arc-shaped groove 204g is provided on one side of the irregularly shaped block 204e. The groove 204g is used to position the top column 204k during rotation. The clamping component also includes a sliding rod 204h disposed on the outside of the sliding frame 204b and a return spring 204i sleeved on the outside of the sliding rod 204h. The two ends of the return spring 204i are respectively connected to the side wall of the fixed ring 204a and the side wall of the sliding frame 204b. A limit plate 204j is provided on one side of the sliding rod 204h, which is used to limit the sliding rod 204h.

[0041] In use: When rotating the rotating ring 202a, the internal irregular block 204e rotates accordingly, thereby squeezing the top column 204k and causing the top column 204k to slide, causing the inner arc-shaped clamping plate 204c to move and assist in clamping and fixing the insertion column 201b. At the same time, during the rotation of the rotating ring 202a, when the top rod 203c is at the highest point of the arc-shaped protrusion 202b, the spherical top block 204d on one side of the top column 204k can fall into the arc-shaped groove 204g of the irregular block 204e for auxiliary fixation. Since it is an arc-shaped groove 204g, the spherical top block 204d can also slide out during rotation. In addition, through the setting of the rotating ring 202a, arc-shaped protrusion 202b, irregular block 204e and arc-shaped curved surface 204f, it is possible to install and disassemble only by rotating in the same direction, without having to change the direction of rotation to install or disassemble, further improving the installation and disassembly efficiency of the device.

[0042] The remaining structure is the same as that in Example 1.

[0043] Example 3

[0044] Reference Figure 9 This is the third embodiment of the present invention, which differs from the second embodiment in that: a pressure sensor 102a is installed in the GIS compartment to simultaneously collect the SF6 and O2 gas contents in the GIS chamber, and the information is combined to determine the fault and issue a signal.

[0045] 1. The pressure in the GIS compartment decreases, triggering a red alarm signal and starting the fan;

[0046] 2. SF6 was detected in the GIS room, and a yellow alarm signal was issued;

[0047] 3. Low O2 content in the GIS room triggers a yellow alarm signal;

[0048] The pressure in the GIS compartment decreased and extremely high SF6 / low O2 content was detected, triggering a red alarm signal and starting the fan.

[0049] In use: After installing pressure sensor 102a, simultaneously collect the SF6 and O2 gas contents in the GIS chamber, and combine the information to determine the fault and issue signals: If the pressure in the GIS compartment decreases, issue a red alarm signal and start the fan; if SF6 is detected in the GIS chamber, issue a yellow alarm signal; if the O2 content in the GIS chamber is low, issue a yellow alarm signal; if the pressure in the GIS compartment decreases and SF6 is too high / O2 content is low, issue a red alarm signal and start the fan.

[0050] The remaining structure is the same as that in Example 2.
