[0002] The zinc oxide lightning arrester in a power system is a lightning arrester with good protection performance. It utilizes the good non-linear volt-ampere characteristics of zinc oxide, so that the current flowing through the lightning arrester is extremely small under normal operating voltage. When overvoltage acts, the resistance drops sharply, and the energy of the overvoltage is discharged to achieve the protection effect, and it is widely used in substations of power systems.

[0003] Since the zinc oxide lightning arrester in the power system is often exposed to wind and rain during use, and it is impossible to know in advance when a failure occurs during use, there may be potential safety hazards in the substation. Therefore, an on-line monitoring device is needed to on-line monitor the shaking state and use temperature of the lightning arrester during use. Since the lightning arrester needs to be regularly maintained during long-term use, it is necessary to separate the lightning arrester and the on-line monitoring component regularly, so as to remove the lightning arrester separately. Therefore, an on-line monitoring device for the operating state of a zinc oxide lightning arrester in a power system that is convenient for the installation and disassembly of the lightning arrester is needed.

[0049] One end of the intermediate member 14 far from the connecting member 12 is connected to the chassis 16.

[0050] Specifically, the lightning arrester 20 is connected to the connecting member 12. Specifically, here it can be welded or clamped. The monitoring member 18 is arranged in the intermediate member 14 and the chassis 16, and the lightning arrester 20 passes through the middle positions of the connecting member 12, the intermediate member 14, and the chassis 16 in sequence. By connecting and disconnecting the connecting member 12 and the intermediate member 14, the connection and disassembly between the lightning arrester 20 and the monitoring member 18 are realized. A fixing member 122 is provided at the lower end of the connecting member 12, and a first connecting portion 142 is provided at the upper end of the intermediate member 14. The first connecting portion 142 and the fixing member 122 are connected by a locking member 123. By adjusting the locking member 123, the connection and disassembly between the first connecting portion 142 and the fixing member 122 can be realized, so as to realize the connection and disassembly between the connecting member 12 and the intermediate member 14. Finally, the connection and disassembly between the lightning arrester 20 and the monitoring member 18 are realized.

[0051] The lightning arrester 20 is connected to the connecting member 12, the intermediate member 14 is connected to the chassis 16, and the monitoring member 18 is arranged on the intermediate member 14 and / or the chassis 16. By connecting the connecting member 12 and the intermediate member 14, the lightning arrester 20 and the monitoring member 18 can be connected; the connecting member 12 and the intermediate member 14 are detachably connected through the fixing member 122 and the first connecting member 12. By adjusting the locking member 123, it is convenient to connect or disconnect the first connecting portion 142 and the fixing member 122, so as to facilitate the connection or separation of the connecting member 12 and the intermediate member 14, and facilitate the disassembly and installation connection between the lightning arrester 20 and the monitoring member 18, so as to facilitate the regular maintenance of the lightning arrester 20.

[0052] Combined with Figures 1-6 and Figure 8, the first connecting portion 142 includes a receiving section 142a and an extending section 142b extending from the receiving section 142a toward one end away from the lightning arrester 20. The receiving section 142a is configured to receive the monitoring member 18.

[0053] The intermediate member 14 includes an intermediate plate and a side wall 143 located on the outer periphery of the intermediate plate. The first connecting portion 142 is located on the upper surface of the intermediate plate, and the extending section 142b penetrates through the side wall 143.

[0054] One end of the connecting member 12 close to the intermediate member 14 is provided with a notch 121 through which the extending section 142b can pass and enter the fixing member 122.

[0055] In one embodiment, there are four notches 121, first connecting portions 142, and fixing members 122.

[0056] The intermediate plate is disk-shaped.

[0057] Specifically, the intermediate plate and the side wall 143 surrounding the outer periphery of the intermediate plate form the intermediate member 14. Four first connecting portions 142 are fixedly connected to the upper surface of the intermediate plate. The four first connecting portions 142 are spaced apart and symmetrically arranged. The first connecting portion 142 further includes a receiving section 142a and an extending section 142b. The extending section 142b extends from the receiving section 142a toward the side wall 143 near the outer periphery of the intermediate plate and penetrates through the side wall 143. A monitoring member 18, specifically a thermocouple module 182, is installed in each receiving section 142a.

[0058] The lower end of the connecting member 12 is provided with four notches 121 through which the extending section 142b can pass and be snapped into the fixing member 122. In this embodiment, the four notches 121, the first connecting portions 142, and the four fixing members 122 are arranged in one-to-one correspondence. Among them, the structures of each notch 121, the first connecting portion 142, and each fixing member 122 are the same. Only one of them will be described later, and specific details will not be elaborated one by one.

[0059] Combined with Figures 2-4 , one end of the fixing member 122 close to the notch 121 is provided with a notch 122a into which the extending section 142b can be snapped. The locking member 123 is matched with the extending section 142b, and the locking member 123 is rotatably arranged between the fixing member 122 and the extending section 142b.

[0060] The fixing member 122 is provided with a guiding groove 122b. An operating member 124 penetrating through the guiding groove 122b is connected to the locking member 123. The operating member 124 is used to adjust the position of the locking member 123 and lock the locking member 123.

[0061] Combined with Figure 4, Further, the fixing member 122 is sleeved outside the extension section 142b. Both the extension section 142b and the fixing member 122 are cylindrical, and the width of the notch 122a is the same as the width of the gap 121.

[0062] Specifically, a notch 122a is provided at the lower end of the fixing member 122. The width of the notch 122a is the same as the width of the gap 121, and both are widths that allow the extension section 142b to pass through. The locking member 123 can rotate between the fixing member 122 and the extension section 142b. Specifically, the extension section 142b is cylindrical, one side of the locking member 123 close to the extension section 142b is an arc, and the other side of the locking member 123 away from the extension section 142b is also an arc. Moreover, the radian of the locking member 123 can at least block the gap 121 and the notch 122a, thereby preventing the extension section 142b from passing through. When the locking member 123 rotates to the position of the gap 121, the extension section 142b can be fixed within the fixing member 122, thereby realizing the fixation of the connecting member 12 and the intermediate member 14. Conversely, when the locking member 123 rotates away from the gap 121, the extension section 142b can be taken out of the fixing member 122, thereby realizing the disassembly of the connecting member 12 and the intermediate member 14.

[0063] In detail, a guiding groove 122b is formed on the fixing member 122, and an operating member 124 is fixedly connected to the locking member 123. The operating member 124 passes through the guiding groove 122b. Driving the operating member 124 can drive the locking member 123 to rotate between the fixing member 122 and the extension section 142b, thereby facilitating the adjustment of the position of the locking member 123 and locking the locking member 123 to fix the position of the locking member 123.

[0064] Combined with Figure 3 , the operating member 124 includes a main body 124a and a locking portion 124b. One end of the main body 124a is connected to the locking member 123, and the other end of the main body 124a passes through the guiding groove 122b and is threadedly connected to the locking portion 124b.

[0065] Specifically, the main body 124a is rod-shaped. One end of the main body 124a is connected to the locking member 123, and the other end of the main body 124a passes through the guiding groove 122b and is connected to the locking portion 124b. The locking portion 124b is a nut, and the nut can be threadedly connected to the other end of the main body 124a, thereby realizing the fixation of the main body 124a, and then fixing the position of the locking member 123.

[0066] Combined with Figures 6-8 , the intermediate member 14 includes an intermediate plate and a side wall 143 located on the outer periphery of the intermediate plate. The lower end of the intermediate member 14 is connected to the upper end of the chassis 16. At least two support members 162 are provided on the upper surface of the chassis 16. The connection between the intermediate member 14 and the chassis 16 enables the support members 162 to be clamped between the intermediate plate and the chassis 16.

[0067] The monitoring component 18 includes a thermocouple module 182 and a pressure sensing module 184. The first connecting portion 142 includes a receiving section 142a and an extending section 142b. The thermocouple module 182 is connected within the receiving section 142a, and the working end of the thermocouple module 182 contacts the lightning arrester 20. The pressure sensing module 184 is located within the support member 162.

[0068] There are four support members 162.

[0069] Specifically, the lower end of the intermediate plate is connected to the upper end of the chassis 16. Four support members 162 are fixedly connected to the upper surface of the chassis 16. The four support members 162 are spaced apart and symmetrically arranged. After the intermediate member 14 is connected to the chassis 16, the four support members 162 are clamped between the intermediate plate and the chassis 16. Among them, the structure of each support member 162 is the same. Only one of them will be described later, and details will not be elaborated one by one.

[0070] The monitoring component 18 includes a thermocouple module 182 and a pressure sensing module 184. Among them, the thermocouple module 182 is connected within the receiving section 142a. The working end of the thermocouple module 182 is the upper end, and the upper end penetrates through the side wall 143 of the connecting member 12 to contact the lightning arrester 20. Specifically, one thermocouple module 182 is provided within each receiving section 142a. The pressure sensing module 184 is located within the support member 162. Specifically, one pressure sensing module 184 is provided within each pressure sensing module 184.

[0071] Combined with Figure 7 , one end of the support member 162 connected to the intermediate member 14 is provided with a first groove 162a, and an airbag ring 162b is provided within the first groove 162a. The airbag ring 162b is clamped between the support member 162 and the intermediate plate.

[0072] Specifically, a first groove 162a is formed in the middle of each support member 162, and an airbag ring 162b is installed within each first groove 162a. Therefore, after the intermediate member 14 is connected to the chassis 16, the airbag ring 162b is clamped between the upper end of the support member 162 and the intermediate member 14, which can play a certain buffering role.

[0073] Combined with Figure 7 and Figure 8 , the lower surface of the intermediate plate is provided with a boss 145, and the upper surface of the chassis 16 is provided with a concave groove 166 matching the boss 145. At least two limiting rods 145a are horizontally provided on the boss 145, and a limiting groove 166a for the limiting rods 145a to insert is provided within the concave groove 166. The connection between the chassis 16 and the intermediate member 14 enables the boss 145 to enter the concave groove 166, and the limiting rods 145a are inserted into the limiting grooves 166a;

[0074] On the outer periphery of the further concave platform 166, there is an extrusion airbag 164a located on the upper surface of the chassis 16. On the outer periphery of the convex platform 145, there is an extrusion ring 147 located on the lower surface of the intermediate plate. Between the extrusion ring 147 and the intermediate plate, there is a telescopic rod 144. The connection between the intermediate member 14 and the chassis 16 makes the extrusion ring 147 abut against the extrusion airbag 164a.

[0075] Furthermore, on the upper surface of the chassis 16, there is a second groove 164. The extrusion airbag 164a is located within the second groove 164. The connection between the intermediate member 14 and the chassis 16 makes the extrusion ring 147 located within the second groove 164.

[0076] Both the limiting rods 145a and the limiting grooves 166a are four in number.

[0077] Specifically, when the intermediate member 14 is connected to the chassis 16, the convex platform 145 enters the concave-convex part, and the four limiting rods 145a are respectively inserted into the four limiting grooves 166a, thereby enabling the connection between the intermediate member 14 and the chassis 16. The diameter of the limiting groove 166a is larger than the diameter of the limiting rod 145a, which can limit the connection and sway of the intermediate plate for positioning.

[0078] Further, on the outer periphery of the concave platform 166, there is a second groove 164. The extrusion airbag 164a is located within the second groove 164. On the outer periphery of the convex platform 145, there is an extrusion ring 147. Specifically, on the lower surface of the intermediate plate, there is a fixedly connected telescopic rod 144, and the lower end of the telescopic rod 144 is fixedly connected to the extrusion ring 147. Therefore, when the intermediate member 14 is connected to the chassis 16, the extrusion airbag 164a abuts against the extrusion ring 147, and both the extrusion airbag 164a and the extrusion ring 147 are located within the second groove 164. When lightning protection occurs and there is shaking and pressure, while the four pressure sensing modules 184 monitor the force on the lightning arrester 20, the lightning arrester 20 can also be assisted in being supported through structures such as the extrusion airbag 164a, the extrusion ring 147, the second groove 164, and the telescopic rod 144, improving the stability strength of the lightning arrester 20. And under the expansion action of the extrusion airbag 164a and the extrusion ring 147, the use stability and strength of the lightning arrester 20 in strong wind weather are improved.

[0079] Inside the support member 162, there is a channel 165 connecting the extrusion airbag 164a and the airbag ring 162b.

[0080] Combined Figure 1 , Figure 5 , Figure 6 and Figure 8 , the side wall 143 on the outer periphery of the intermediate plate is stepped. The intermediate plate is located at the step. The lower end of the connecting member 12 is sleeved on the upper end of the intermediate member 14, and the upper end of the intermediate member 14 is sleeved on the upper end of the chassis 16.

[0081] The fixing member 122 is sleeved on the extension section 142b, and both the extension section 142b and the fixing member 122 are cylindrical.

[0082] The width of the notch 122a is the same as the width of the gap 121.

[0083] Specifically, the side wall 143 on the outer periphery of the intermediate plate is stepped, so that the intermediate member 14 is a stepped cylinder. The intermediate plate is located at the stepped part within the side wall 143. The lower end of the connecting member 12 is sleeved on the upper end of the intermediate member 14, and the lower end of the intermediate member 14 is sleeved on the upper end of the chassis 16. Both the upper and lower ends of the intermediate member 14 are cylindrical, and the connecting member 12 is also cylindrical.

[0084] Combined Figures 1-8 , the on-line monitoring device 10 for the operating state of the zinc oxide lightning arrester 20 in the power system further includes a controller.

[0085] The accommodating section 142a is an accommodating groove. The thermocouple module 182 includes a body 182a and a first wire 182b. The body 182a is located in the accommodating groove, and the first wire 182b penetrates into the extension section 142b and extends out of the connecting member 12 through the extension section 142b.

[0086] The lightning arrester 20 includes a composite housing 22, an insulating sleeve 24, and a core 26. The upper end of the body 182a is the working end of the thermocouple module 182. The working end of the thermocouple module 182 penetrates the top of the connecting member 12 and is inserted between the insulating sleeve 24 and the core 26. The core 26 penetrates the intermediate plate, the boss 145, the concave platform 166, and the intermediate area of the chassis 16.

[0087] The pressure sensing module 184 is connected with a second wire 184b. The second wire 184b penetrates the intermediate plate and the extension section 142b, and extends out of the connecting member 12 through the extension section 142b. The controller is electrically connected to the first wire 182b and the second wire 184b.

[0088] Specifically, the body 182a is located in the accommodating groove, and the first wire 182b penetrates the extension section 142b and extends out of the side wall 143 of the connecting member 12 through the extension section 142b. More specifically, the extension section 142b is a tubular structure.

[0089] The composite housing 22 and the insulating sleeve 24 are welded or clamped to the upper end of the connecting member 12. The core 26 sequentially penetrates the connecting member 12, the intermediate member 14, and the chassis 16. The upper end of the thermocouple module 182 penetrates the top side wall 143 of the connecting member 12 and is inserted between the insulating sleeve 24 and the core 26, so as to monitor the temperature change during the use of the lightning arrester 20.

[0090] The pressure sensing module 184 can monitor the shaking state of the lightning arrester 20. The second wire 184b of the pressure sensing module 184 first penetrates the middle plate, then penetrates the extension section 142b and extends out of the side wall 143 of the connecting member 12 through the extension section 142b. The controller is electrically connected to the first wire 182b and the second wire 184b, and four controllers are electrically connected and incorporated into the control system. Transferring the first wire 182b and the second wire 184b out through a dedicated pipeline can prevent the device from leaking water.

[0091] When installing the lightning arrester 20:

[0092] Move the connecting member 12 connected to the lightning arrester 20 above the intermediate member 14, align each notch 121 and notch 122a with each extension section 142b, and move the connecting member 12 downward. At this time, the extension section 142b passes through the notch 121 and notch 122a and enters the fixing member 122. Slide the main body 124a along the guiding groove 122b until the locking member 123 is located at the notch 121 and notch 122a, and tighten the locking portion 124b. Repeat the above actions for each locking member 123. At this time, the connecting member 12 connected to the lightning arrester 20 and the intermediate member 14 equipped with the monitoring member 18 can be installed and connected.

[0093] When disassembling the lightning arrester 20:

[0094] Loosen the locking portion 124b, slide the main body 124a along the guiding groove 122b until the locking member 123 slides to a position away from the notch 121 and notch 122a. Repeat the above actions for each locking member 123. At this time, lift the connecting member 12 connected to the lightning arrester 20 upward, and the extension section 142b can pass through the notch 121 and notch 122a, so that the connecting member 12 can be disassembled from the intermediate member 14.

[0095] When installing the intermediate member 14 and the chassis 16:

[0096] It should be emphasized that the pressure sensing module 184 is installed on the chassis 16, and the thermocouple module 182 is installed on the intermediate member 14. The chassis 16 and the intermediate member 14 are installed. Therefore, the monitoring member 18 including the pressure sensing module 184 and the thermocouple module 182 is installed inside the intermediate member 14 and the chassis 16.

[0097] During installation, place the boss 145 into the concave-convex, and limit the position through the connection between the limiting groove 166a and the limiting rod 145a. The collision and abutment between the extrusion airbag 164a and the extrusion ring 147 can assist in supporting and buffering and shock absorption, and can also improve the stable support strength. The airbag ring 162b plays a role in buffering and shock absorption and facilitates the operation of the pressure sensing module 184.

[0098] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent shall be subject to the appended claims.
