Description

Technical Field

[0001] The utility model relates to the field of surge protector equipment, in particular to a surge protector signal transmission device and a surge protector. Background Art

[0002] The function of a surge protector is to protect the lines it is connected to. The surge protector is used in power circuits or communication lines. Its principle is to conduct and shunt the impact current through the internal varistor, thereby preventing the impact current from damaging the equipment on the power circuit or communication line. During daily use, the lightning protection components inside the surge protector will be damaged, causing the leakage current to continue to flow through the surge protector. The function of the thermal release module is to enable the surge protector to be able to disconnect from the protected circuit in a timely and reliable manner when a continuous small current flows through it.

[0003] When a thermal trip occurs in an existing surge protector, the action signal of the action component is converted into an electrical signal through the cooperation between the action component and the sensor or circuit structure in the smart box. The analog electrical signal is then converted into a digital electrical signal through the relevant circuit in the smart box, and the electrical signal is sent to an external host computer through a communication unit. The smart box needs to be powered by an external or its own power supply to realize the operation of each internal power-consuming unit. Therefore, the deployment and operation of traditional surge protectors need to consider power supply factors, and the setting of external power supply lines and the maintenance of their own power supply have a greater impact on it.

[0016] Beneficial Effects

DETAILED DESCRIPTION

[0024] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0025] Embodiment 1

[0026] like Figures 1 to 4 A surge protector 17 signal transmission device shown includes a smart box and an actuating part 6 of a thermal release assembly. The smart box includes a chassis part 1 and an optical fiber 2. A first bracket structure is provided at a position of the chassis part 1 corresponding to the actuating part 6. The optical fiber 2 is overlapped on the first bracket structure at a corresponding position. The actuating part 6 can cooperate with the first bracket structure to bend the optical fiber 2, and the end of the optical fiber 2 is coupled to the monitoring host 15.

[0027] In order to get rid of the constraints of existing power supply factors on the deployment and operation of the surge protector 17, in this solution, when the surge protector 17 undergoes a thermal trip action, the action part 6 cooperates with the optical fiber 2 in the smart box. The optical fiber 2 is mounted on the first bracket structure of the chassis part 1. The action part 6 moves to cooperate with the first bracket structure, causing the optical fiber 2 at this location to bend. The bending of the optical fiber 2 at this location can be monitored by the monitoring host 15 coupled to its end. The monitoring host 15 obtains a signal that the surge protector 17 has undergone a thermal trip action and sends the signal to the host computer. One end of the optical fiber 2 in the present solution is coupled to the monitoring host 15. Preferably, the monitoring host 15 includes an optical time domain reflectometer 16. The optical time domain reflectometer 16 can obtain attenuation information based on the backscattered light generated when the light propagates in the optical fiber 2. This characteristic can be used to locate the fault point of the optical fiber 2. When the actuating member 6 and the corresponding position of the optical fiber 2 are offset to cause the optical fiber 2 to bend at that location, the optical time domain reflectometer 16 can measure the light information at that location, thereby obtaining information that the surge protector 17 corresponding to the bending point of the optical fiber 2 has undergone a thermal tripping action.

[0028] Compared with the traditional solution, the method used in this solution to obtain the action signal of the action part 6 in the thermal trip assembly and send the action signal of the action part 6 to the external host computer does not need to power the smart box of the surge protector 17 itself, and the smart box does not have a power consumption unit. Therefore, the surge protector 17 in this solution can be deployed and operated in areas without power supply conditions. At the same time, the surge protector 17 does not have a built-in power supply, and there is no maintenance of its own power supply. The monitoring host 15 is located at the remote end, and it is connected to the surge protector 17 through an optical fiber 2. The transmission of the thermal trip signal of the surge protector 17 is realized through the optical path of the optical fiber 2. Compared with the existing transmission method through wireless signals, the optical path of the optical fiber 2 is not easy to be interfered with.

[0029] In an optional embodiment, one optical fiber 2 cooperates with at least two first support structures.

[0030] Existing surge protectors 17 are often multi-linked, that is, multiple lightning protection units are matched with one smart box, and the thermal trip components of multiple lightning protection units collect thermal trip action signals through one smart box. In this solution, a chassis part 1 is matched with multiple lightning protection elements, and a first bracket structure on the chassis part 1 corresponds to an action part 6 of the thermal trip component of a lightning protection element. The above multiple first bracket structures all correspond to an optical fiber 2 and a monitoring host 15 located at the end of the optical fiber 2. The optical fiber 2 is located in the chassis part 1 and passes through each first bracket structure in turn, that is, it corresponds to each lightning protection element in turn. The monitoring host 15 is located at the far end, and through an optical fiber 2, the thermal trip action signal of the thermal trip component of each lightning protection unit matched with the optical fiber 2 can be measured.

[0031] For example, in the direction from the monitoring host 15 to the far end of the optical fiber 2, there are lightning protection unit a, lightning protection unit b and lightning protection unit c in sequence. The optical time domain reflectometer 16 of the monitoring host 15 can measure the thermal tripping action signal of any one of the three lightning protection units by measuring the wavelength and pulse width under the influence of its measurement blind area, dynamic range and the maximum length of the optical fiber 2. If the lightning protection unit c undergoes thermal tripping action, its action member 6 cooperates with the first bracket structure at the corresponding position to cause the optical fiber 2 at that position to bend. The optical time domain reflectometer 16 measures the bending at that position, and obtains the protection signal according to the position information of the three lightning protection units pre-recorded in the monitoring host 15. The lightning protection unit c undergoes a thermal tripping action; if the lightning protection unit a undergoes a thermal tripping action first, and then the lightning protection unit c undergoes a thermal tripping action, the actuating member 6 of the lightning protection unit a first cooperates with the first bracket structure at the corresponding position to cause the optical fiber 2 at that position to bend, and the optical time domain reflectometer 16 measures the bend at that position, and the monitoring host 15 obtains that the lightning protection unit a undergoes a thermal tripping action, and the actuating member 6 of the lightning protection unit c then cooperates with the first bracket structure at the corresponding position to cause the optical fiber 2 at that position to bend, and the optical time domain reflectometer 16 can measure the bend of the optical fiber 2 at the farther end when the optical fiber 2 at the closer end has already been bent, and the monitoring host 15 obtains that the lightning protection unit c undergoes a thermal tripping action.

[0032] Alternatively, since the measurement blind spot distance is greater than the distance between two adjacent first bracket structures along the extension direction of the optical fiber 2, the optical time domain reflectometer 16 cannot distinguish between the lightning protection unit a, lightning protection unit b and lightning protection unit c which are closer. If a thermal trip occurs in the lightning protection unit a or the lightning protection unit c, the optical time domain reflectometer 16 measures the bend at that position, but cannot distinguish between the incoming lines of the lightning protection unit a and the lightning protection unit c, and needs to be distinguished through manual detection based on the information uploaded by the monitoring host 15.

[0033] In an optional embodiment, the first bracket structure includes a support member 7, which is fixedly connected to the chassis member 1. Along the extension direction of the optical fiber 2, two support members 7 are arranged on the chassis member 1 at intervals, and a matching groove for the action member 6 to move into is formed between the two support members 7. The support member 7 has an abutment end face, and the optical fiber 2 passes through the abutment end face and is in contact with the abutment end face or there is a gap.

[0034] The optical fiber 2 can be bent between the two support members 7 by being pushed by the actuating member 6. A tensioning member is provided on the chassis member 1. The optical fiber 2 is coiled in the chassis member 1 by being wound around the tensioning member and passes through each first bracket structure in turn and maintains a tensioned state. The distance between the optical fiber 2 at the tensioning member and the chassis member 1 is smaller than the distance between the abutting end face on the support member 7 and the chassis member 1. Therefore, when passing through the support member 7, the optical fiber 2 fits with the abutting end face of the support member 7 and is lifted to a distance away from the chassis member 1 by the abutting end face, so that the optical fiber 2 can generate a deformation that can be measured by the monitoring host 15 when being pushed by the actuating member 6.

[0035] In the present scheme, a chassis component 1 cooperates with multiple lightning protection elements. The two support members 7 on the chassis component 1 form a group of actuating members 6 of a thermal release assembly corresponding to a lightning protection element. The actuating member 6 is inserted between the two support members 7. The optical fiber 2 located between the two support members 7 is bent, and the deformation range is limited to the two support members 7, and will not affect the optical fiber 2 between two adjacent support members 7.

[0036] In an optional embodiment, the first bracket structure also includes a positioning member 8, which is located between the two support members 7 and fixedly connected to the chassis member 1. A channel structure 11 is provided on the positioning member 8. An opening for inserting the actuating member 6 into the channel structure 11 is provided at one end of the positioning member 8 facing the actuating member 6. The positioning member 8 is also provided with at least two through openings 10 for the optical fiber 2 to pass through the channel structure 11.

[0037] The function of the positioning member 8 is to enable the actuating member 6 to accurately push the optical fiber 2 to bend it. Specifically, a channel structure 11 is provided on the positioning member 8. The actuating member 6 can be inserted into the channel structure 11 when it moves. Two through holes 10 are provided on the side wall surface of the positioning member 8 corresponding to the channel structure 11. The optical fiber 2 can pass through the through hole 10 to enter the channel structure 11, and then pass out through the other through hole 10, so that a part of the optical fiber 2 is located in the channel structure 11, and cannot move due to the limitation of the through hole 10. When the actuating member 6 is inserted into the channel structure 11, the outer wall surface of the actuating member 6 fits with the inner wall surface of the channel structure 11, ensuring that the optical fiber 2 can be against the end of the actuating member 6, and bend toward the side away from the opening of the channel structure 11 under the push of the actuating member 6.

[0038] Preferably, the channel structure 11 is a cylindrical cavity, the two through openings 10 are relatively arranged along the radial direction of the channel structure 11, and the optical fiber 2 passes through the axis of the channel structure 11 in the channel structure 11. Specifically, the channel structure 11 is a cylindrical cavity, the two through openings 10 are relatively arranged along the radial direction of the channel structure 11, and the optical fiber 2 passes through the axis of the channel structure 11 in the channel structure 11.

[0039] Alternatively, the positioning member 8 is also used to allow the optical fiber 2 to be coiled in the chassis member 1, so that the optical fiber 2 is coiled in the chassis member 1 and passes through each first bracket structure in turn and maintains a tensioned state. The channel structure 11 is a cylindrical cavity, and the two through openings 10 are relatively arranged along the radial direction of the channel structure 11. The optical fiber 2 passes through the axis of the channel structure 11 in the channel structure 11. Specifically, the channel structure 11 is a cylindrical cavity, and the two through openings 10 are arranged along the radial direction of the channel structure 11, and there is an angle between the axes of the two. After passing through the channel structure 11, the extension direction of the optical fiber 2 changes.

[0040] In an optional embodiment, a second clamping member 9 is provided on the positioning member 8, and the two second clamping members 9 are spaced apart in a direction perpendicular to the extension direction of the optical fiber 2, and a channel structure 11 and a through port 10 are formed between the two second clamping members 9.

[0041] One end of the positioning member 8 is fixed on the chassis member 1, and the other end is provided with the lower section of the channel structure 11. Two second clamping members 9 are arranged at intervals on the end faces on both sides of the opening. The wider part in the middle of the gap forms the upper section of the channel structure 11, which is connected with the lower section of the channel structure 11 through the opening at the end of the positioning member 8 to form a complete channel structure 11 for the insertion of the actuating member 6. Through-ports 10 are formed at the narrower parts on both sides. The optical fiber 2 can be placed between the two second clamping members 9 through the edge notch of the gap between the two second clamping members 9 and is constrained by the two second clamping members 9 to facilitate the assembly between the optical fiber 2 and the chassis member 1.

[0042] Alternatively, a first clamping member is provided on the actuating member 6 , and two first clamping members are arranged at intervals along a direction perpendicular to the extending direction of the optical fiber 2 at one end of the actuating member 6 facing the supporting member 7 .

[0043] The gap between the two first clamping parts is used to constrain the optical fiber 2 so that when the actuating member 6 pushes the optical fiber 2 , the optical fiber 2 can be clamped into the gap between the two first clamping parts and move with the actuating member 6 .

[0044] In an optional embodiment, two connecting terminals 5 are provided on the chassis member 1, and the optical fiber 2 includes an inner fiber 18 and an outer fiber 19. The inner fiber 18 is located inside the chassis member 1 and its two ends are respectively connected to the two connecting terminals 5. Two adjacent chassis members 1 are connected via the outer fiber 19 between the connecting terminals 5.

[0045] One monitoring host 15 corresponds to multiple chassis components 1, and each chassis component 1 cooperates with several lightning protection modules to form a multi-channel surge protector 17. The monitoring host 15 and the chassis component 1, and the chassis components 1 and the chassis components 1 are connected through the external fiber 19. The chassis component 1 cooperates with the first bracket structure and the second bracket structure inside the chassis component 1 through the internal fiber 18, and the internal fiber 18 and the external fiber 19 are connected through the connecting terminal 5, so that an optical fiber 2 composed of the inner fiber 18 and the outer fiber 19 connects the monitoring host 15 with each multi-channel surge protector 17.

[0046] There are two connecting terminals 5, one forming an inlet and the other forming an outlet. When connecting the chassis components 1, one end of an outer fiber 19 is connected to a connecting terminal 5 on one chassis component 1 for forming an inlet, and the other end is connected to a connecting terminal 5 on another chassis component 1 for forming an outlet.

[0047] In an optional embodiment, a window structure is provided on the chassis 1 , and two ends of the optical fiber 2 respectively pass through the window structure and extend out of the chassis 1 .

[0048] Two window structures, one forming an inlet and the other forming an outlet, when connecting the chassis 1, one end of the optical fiber 2 extends through the window structure for forming an inlet on the chassis 1, and is connected to the optical fiber 2 extending through the window structure for forming an outlet on the other chassis 1. The two optical fibers 2 are fused or the two are fused to form a connection section.

[0049] Embodiment 2

[0050] In an optional embodiment, a second support structure is provided at the chassis member 1 corresponding to the dividing piece 12 of the backup protection assembly, and the second support structure includes two door frames 13. The two door frames 13 are spaced apart along the extension direction of the optical fiber 2 and are fixedly connected to the chassis member 1. A spacing structure for moving the dividing piece 12 in is formed between the two door frames 13. A third clamping member 14 is provided on the door frames 13. The two third clamping members 14 are spaced apart along a direction perpendicular to the extension direction of the optical fiber 2 at one end of the door frame 13 facing the dividing piece 12. A positioning groove for the optical fiber 2 to pass through is formed between the two third clamping members 14. The optical fiber 2 passes through the two door frames 13 in sequence.

[0051] The surge protector 17 includes a backup protection component, and each lightning protection unit corresponds to a backup protection component. The backup protection breaker of the existing surge protector 17 controls the action of the electromagnetic release through a current transformer, and the action side of the electromagnetic release cooperates with the disconnecting piece 12 in the spacing structure arranged on the grounding loop through a linkage mechanism. When the disconnecting action of the backup protection breaker is triggered, the electromagnetic release drives the hook to disengage from the disconnecting piece 12, so that the disconnecting piece 12 moves to disengage from the grounding loop under the action of the spring, thereby disconnecting the grounding loop. The action signal of the disconnecting piece 12 in this solution can be transmitted to the monitoring host 15 through the optical fiber 2.

[0052] Specifically, the optical fiber 2 can be bent between the two door frames 13 by the push of the dividing piece 12. A tensioning piece is provided on the chassis part 1. The optical fiber 2 is coiled in the chassis part 1 by winding around the tensioning piece and passes through each first bracket structure in turn and maintains a tensioned state. The distance between the optical fiber 2 at the tensioning piece and the chassis part 1 is smaller than the distance between the bottom surface of the positioning groove on the door frame 13 and the chassis part 1. Therefore, when passing through the door frame 13, the optical fiber 2 fits with the bottom surface of the positioning groove on the door frame 13 and is lifted to a distance away from the chassis part 1 by the bottom surface of the groove, so that the optical fiber 2 can generate a deformation that can be measured by the monitoring host 15 when it is pushed by the dividing piece 12.

[0053] In the present scheme, a chassis component 1 cooperates with multiple backup protection components. The two door frames 13 on the chassis component 1 form a group of disconnecting components 12 corresponding to one backup protection component. The disconnecting component 12 is inserted into the spacing structure between the two door frames 13. The optical fiber 2 between the two door frames 13 is bent, and the deformation range is limited to the two door frames 13, which will not affect the optical fiber 2 between two adjacent door frames 13.

[0054] This solution and the first embodiment share one optical fiber 2, that is, the optical fiber 2 corresponds to at least two areas in the chassis 1, one of which is the area 4 corresponding to the thermal trip assembly, and the other is the area 3 corresponding to the backup protection assembly. After the chassis 1 is matched with multiple surge protectors 17, the first bracket assemblies are arranged in sequence in the area 4 corresponding to the thermal trip assembly according to the arrangement of the surge protectors 17, and the second bracket assemblies are arranged in sequence in the area 3 corresponding to the backup protection assembly according to the arrangement of the surge protectors 17. The optical fiber 2 passes through the above-mentioned two areas in sequence in the chassis 1, and when passing through the area 4 corresponding to the thermal trip assembly, it cooperates with each first bracket assembly in sequence, and when passing through the area 3 corresponding to the backup protection assembly, it cooperates with each second bracket assembly in sequence. That is, there are a number of deformation sites on the optical fiber 2, corresponding to each first bracket assembly and the second bracket assembly. If the blind area distance measured by the monitoring host 15 is smaller than the distance between two adjacent deformation sites along the extension direction of the optical fiber 2, the optical time domain reflectometer 16 measures that any deformation site on the optical fiber 2 is bent. According to the position information pre-entered in the monitoring host 15, it is determined whether a specific lightning protection unit has a thermal tripping action or a backup protection action.

[0055] Alternatively, because the measurement blind zone distance is greater than the distance between two adjacent deformation sites along the extension direction of the optical fiber 2, the optical time domain reflectometer 16 cannot distinguish the various deformation sites within the chassis component 1. The optical time domain reflectometer 16 measures the bending of the optical fiber 2, which needs to be distinguished through manual detection based on the information uploaded by the monitoring host 15.

[0056] Embodiment 3

[0057] The surge protector 17 provided by the utility model comprises a lightning protection module and a backup protection module, and the lightning protection module and the backup protection module are respectively fixedly matched with the intelligent box of the thermal release assembly.

[0058] The smart box includes a chassis component 1, and the lightning protection module includes a lightning protection element and a thermal release component, which form a relatively independent integrated component. A backup protection module and a lightning protection module constitute a one-way surge protector 17. A chassis component 1 cooperates with a multi-way surge protector 17 to form a multi-way surge protector 17, and a monitoring host 15 corresponds to multiple multi-way surge protectors 17.

[0059] The thermal release assembly cooperates with the optical fiber 2 in the chassis part 1 of the smart box through the actuating part 6, and the backup protection module also cooperates with the optical fiber 2 in the chassis part 1 of the smart box through the disconnecting part 12. The optical fiber 2 cooperates with the monitoring host 15 to send the action signals of the actuating part 6 and the disconnecting part 12 to the external host computer.
