Description

Technical Field

[0001] This utility model relates to the field of high voltage test safety protection technology, and in particular to a high voltage test safety protection device for substations. Background Technology

[0002] High-voltage testing in substations is a crucial step in ensuring the safe and stable operation of power equipment. It primarily tests the insulation performance and electrical parameters of high-voltage equipment such as transformers, circuit breakers, and cables to ensure they meet operational standards. However, high-voltage testing carries extremely high safety risks. The equipment within the testing area generates high voltage and strong electric fields. If operators accidentally enter the testing area or come into contact with live equipment, it can easily lead to serious accidents such as electric shock and arc burns, even endangering lives.

[0003] During the use of protective devices, safety protection is required during the testing of high-voltage substations. Therefore, two layers of protective structures need to be installed around the high-voltage substation. Otherwise, passersby can easily approach the high-voltage substation and cause danger. Utility Model Content

[0004] This utility model relates to a safety protection device for high-voltage testing in substations. All its fixed inner frames are interconnected to form a protective structure that directly isolates the high-voltage equipment from the external environment. Its robust structure can withstand accidental collisions and human climbing, physically preventing unauthorized personnel or objects from entering the danger zone. It is the first "solid barrier" to ensure the safety of the substation. Then, a protective warning structure is formed on the outermost perimeter of the high-voltage substation using connecting nets and outer poles. This structure not only further expands the protection range but also intercepts approaching passersby in advance, preventing them from directly contacting the inner protection or core equipment and reducing the probability of accidents. In this way, a two-layer protective structure is formed around the high-voltage substation. When a passerby touches the outer protective structure, a bell will ring immediately to quickly attract their attention, more effectively serving as a reminder and prompting passersby to stay away in time.

[0005] In a first aspect, this utility model provides a safety protection device for high-voltage testing in a substation, specifically comprising: a fixed platform; fixed bases are uniformly fixedly installed on the upper edge of the fixed platform, and a row of connecting holes is respectively opened at both ends of the fixed bases; a fixed inner frame is fixedly installed on the upper end of each of the fixed bases; a fixed frame is fixedly installed on the front side of the fixed inner frame at the front middle, and an elastic rope is uniformly connected to the front end of the fixed frame; a vibration alarm is installed in the middle of the elastic rope.

[0006] Vertical poles are installed at the four corners of the fixed platform. Connecting nets are installed on the outer sides of the vertical poles, and connecting outer poles are installed at the outer ends of the connecting nets. Stabilizing blocks are fixedly installed at the lower ends of all the outer poles, and a through conical rod is inserted in the middle of the stabilizing block. Two warning signs are installed on the outer sides of the outer poles at the front and rear ends, and bells are tied to the connecting nets at the front and rear ends.

[0007] Furthermore, slots are provided at the four corners of the fixed platform, a high-voltage substation is fixedly installed in the middle of the fixed platform, and a protective cover is fixedly installed at the top of the fixed platform.

[0008] Furthermore, a set of crossbars is fixedly installed on the inner side of all the fixed inner frames, and through protective bars are evenly inserted on the set of crossbars; guide strips are fixedly installed on the outer side of the fixed inner frames.

[0009] Furthermore, a guide groove is provided on the inner side of the fixed inner frame, and symmetrical connecting threaded rods are fixedly installed on the outer sides of the fixed inner frame at both ends, and retaining rings are rotatably fitted on the connecting threaded rods.

[0010] Furthermore, a spare door is installed in the middle of the fixed inner frame at the rear end, and a front door is installed in the middle of the fixed inner frame at the front end.

[0011] This utility model provides a safety protection device for high-voltage testing in substations, which has the following beneficial effects:

[0012] In this utility model, when the protective device is in use, all the fixed inner frames are interconnected to form a protective structure that can directly isolate the high-voltage equipment from the external environment. Its robust structure can withstand accidental collisions and human climbing, physically preventing unauthorized personnel or objects from entering the danger zone. It is the first "robust barrier" to ensure the safety of the substation. Then, a protective warning structure is formed on the outermost perimeter of the high-voltage substation using connecting nets and outer poles. This structure not only further expands the protection range but also intercepts approaching passersby in advance, preventing them from directly contacting the inner protective layer or core equipment and reducing the probability of accidents. In this way, a two-layer protective structure is formed around the high-voltage substation. When a passerby touches the outer protective structure, a bell will ring immediately to quickly attract the passerby's attention, which can more effectively play a warning role and prompt passersby to stay away in time.

[0013] When an outsider touches the connection network, a bell on the network will sound, alerting people that a protective layer has been installed. The bell immediately emits a clear sound, overcoming visual limitations (such as at night, in foggy weather, or when attention is diverted) to provide a real-time auditory warning. At the same time, the warning signs also indicate the high-voltage danger zone. Conspicuous high-voltage symbols (such as lightning symbols and red borders) and text descriptions (such as "High Voltage Danger, Do Not Touch") reinforce visual warnings, preventing unauthorized personnel from entering and avoiding electric shock accidents.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1 to 4 :

[0024] This utility model proposes a safety protection device for high-voltage testing in substations, comprising: a fixed platform 1; fixed bases 2 are evenly fixedly installed on the upper edge of the fixed platform 1, and a row of connecting holes are respectively opened at both ends of the fixed bases 2; bolts are inserted through the connecting holes on the fixed bases 2 and rotated into the fixed platform 1 to fix and restrict the fixed bases 2, so that the fixed bases 2 will not move when touched; slots 101 are respectively opened at the four corners of the fixed platform 1; a high-voltage substation 102 is fixedly installed in the middle of the fixed platform 1; a protective cover 103 is fixedly installed on the upper end of the fixed platform 1, and the protective cover 103 covers the high-voltage substation 102. By opening the door of the protective cover 103, the components in the high-voltage substation 102 can be operated. The upper end of each of the two fixed inner frames 201 is fixedly installed. When assembling two adjacent fixed inner frames 201, the guide strip 204 on the fixed inner frame 201 is slidably installed in the guide groove 205 of the other fixed inner frame 201, and then the connecting threaded rod 206 is used to pass through the fixed inner frame 201 for connection. Then all the fixed inner frames 201 are fixedly connected to form a stable rectangular guardrail. When one of the fixed inner frames 201 is touched, it will not move or tilt. In this way, the guardrail assembled by all the fixed inner frames 201 surrounds the high-voltage substation 102 in the middle, providing physical isolation and protection for the high-voltage substation 102. In this way, a protective structure is formed on the periphery of the high-voltage substation 102. The inner side of all the fixed inner frames 201 is fixedly installed with A set of horizontal bars 202, with through-bars 203 evenly inserted on the set of horizontal bars 202. Guide strips 204 are fixedly installed on the outer side of the fixed inner frame 201. Guide grooves 205 are opened on the inner side of the fixed inner frame 201. Symmetrical connecting threaded rods 206 are fixedly installed on the outer sides of the left and right ends of the fixed inner frame 201, and retaining rings are rotatably fitted on the connecting threaded rods 206. A spare door 207 is installed in the middle of the rear fixed inner frame 201. When the front door 208 is damaged, the lock on the spare door 207 is opened to enter. Under normal circumstances, the spare door 207 will not be opened. A front door 208 is installed in the middle of the front fixed inner frame 201. Turn off the vibration alarm 211, and then push the middle elastic rope 210 to both sides to form a window. Then from Entering here, the front door 208 is opened, allowing testing of the high-voltage substation 102. A fixed frame 209 is fixedly installed on the front side of the fixed inner frame 201 in the middle of the front end, and elastic ropes 210 are evenly connected to the front end of the fixed frame 209. A vibration alarm 211 is installed in the middle of the elastic rope 210. Before an outsider enters through the front door 208, they need to touch the elastic rope 210 and pull it. At this time, the elastic rope 210 will shake, and the vibration alarm 211 will also shake. Then, the vibration alarm 211 will emit a piercing alarm sound to promptly notify the staff. Vertically upward-pointing vertical rods 3 are installed at the four corners of the fixed platform 1. The lower end of the vertical rods 3 is inserted into the slot 101 to temporarily fix and restrict the vertical rods 3.

[0025] The vertical pole 3 is equipped with a connecting mesh 301 on its outer side, and the outer end of the connecting mesh 301 is equipped with a connecting outer perimeter pole 302. A stabilizing block 303 is fixedly installed at the lower end of each outer perimeter pole 302, and a through-hole conical rod is inserted into the middle of each stabilizing block 303. The lower end of the conical rod in the middle of the stabilizing block 303 reduces resistance when inserted into the ground. The conical rod temporarily fixes and restricts the stabilizing block 303 and the vertical pole 3, pulling and stretching the connecting mesh 301 and the outer perimeter pole 302, forming a protective layer on the outermost perimeter of the high-voltage substation 102. The protective warning structure will cause the bell 305 on the connecting net 301 to sound when an outsider touches it, reminding people that a protective layer has been installed. At the same time, the warning sign 304 will indicate the high-voltage danger zone, preventing unauthorized personnel from entering and avoiding electric shock accidents. After the high-voltage substation 102 is tested, the vertical pole 3 and the connecting net 301 will be completely removed for future use. Two warning signs 304 will be installed on the outer side of the outer pole 302 at both the front and rear ends, and bells 305 will be tied to the connecting net 301 at both the front and rear ends.

[0026] Example 2, based on Example 1, such as Figure 1 and Figure 4 As shown, a front door 208 is installed in the middle of the front fixed inner frame 201, and a fixed frame 209 is fixedly installed on the front side of the front fixed inner frame 201. Elastic ropes 210 are evenly connected to the front end of the fixed frame 209. A vibration alarm 211 is installed in the middle of the elastic rope 210. When the vibration alarm 211 is installed on the front door 208, the vibration alarm 211 will slide and emit a piercing alarm sound during the opening of the front door 208, so as to notify the staff in time. In this way, the staff can know that someone has entered and touched the high-voltage substation 102, and avoid accidentally touching the elastic rope 210 and causing the vibration alarm 211 to sound.

[0027] The working principle of this embodiment is as follows: During use, when assembling two adjacent fixed inner frames 201, the guide strip 204 on the fixed inner frame 201 is slidably installed in the guide groove 205 of the other fixed inner frame 201. Then, a connecting threaded rod 206 is used to connect the fixed inner frames 201. All the fixed inner frames 201 are then fixedly connected to form a stable rectangular guardrail. When one of the fixed inner frames 201 is touched, it will not move or tilt. In this way, the guardrail assembled from all the fixed inner frames 201 surrounds the high-voltage substation 102, providing physical isolation and protection for the high-voltage substation 102. This creates a protective structure around the high-voltage substation 102. When the lower end of the conical rod in the middle of the stabilizing block 303 is inserted into the ground, it reduces resistance. The conical rod is used to temporarily fix and restrict the stabilizing block 303 and the vertical rod 3, pulling and spreading the connecting net 301 and the outer rod 302. This forms a protective warning structure on the outermost perimeter of the high-voltage substation 102. When an outsider touches the connecting net 301, the bell 305 on the connecting net 301 will sound, reminding people that a protective layer has been set up here. At the same time, the warning sign 304 will inform people of the high-voltage danger zone, preventing unauthorized personnel from entering and avoiding electric shock accidents.
