Technical Field
[0001] The utility model relates to the technical field of power supply, in particular to a safety monitoring device for transformer substation equipment. Background Art
[0002] A substation is a place in the power system that transforms voltage and current, receives electric energy and distributes electric energy. Its function is to boost the electric energy generated by the generator and feed it into the high-voltage power grid. Substation equipment is generally located outdoors. While enduring long-term impacts of large current overloads, it also has to withstand the test of harsh external natural conditions. Substation equipment failures often occur due to drastic changes in the external environment. According to statistics, electrical burn failures of internal components of substations account for about 40% of the total substation equipment failures.
[0003] The existing referenceable Chinese utility model patent with announcement number: CN211088064U discloses a substation equipment safety monitoring alarm device, which relates to the field of power supply, including a substation control room, a support base is fixedly installed in the middle of the inner bottom wall of the substation control room, a transformer is fixedly installed in the middle of the upper surface of the support base, a heat dissipation fan is fixedly installed in the middle of the left and right sides of the inner wall of the substation control room, a slide plate is fixedly installed in the middle of the inner top wall of the substation control room, an electric slider is slidably connected inside the slide plate, a temperature sensor is fixedly installed at the bottom of the electric slider, a wire box is fixedly installed on the top of the right side wall of the substation control room, and a spiral data cable is arranged inside the wire box. The utility model arranges a slide plate, an electric slider and a temperature sensor inside the substation control room, and the temperature sensor is an automatic circulating sliding type, which can monitor the temperature of each position inside the substation control room in real time, make accurate judgments, and improve its work efficiency.

The accuracy is low and there is a problem of omission. However, the temperature detection effect of a single temperature sensor is not good, and there are many devices inside the substation control room.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Combined with Figure 1-5 In this embodiment, a safety monitoring device for substation equipment includes: a substation control room 1, a filter screen 11 is fixedly installed on the top of the substation control room 1, and the filter screen 11 is in a "mouth" shape. A rubber layer 12 is fixedly installed inside the substation control room 1.
[0026] An air intake pipe 13 is fixedly installed at the bottom of the substation control room 1, and the air intake pipe 13 is in a "mouth" shape.
[0027] A driving fan 14 is fixedly installed inside the air inlet pipe 13 , and an interception net 15 is fixedly installed at the bottom of the air inlet pipe 13 .
[0028] Specifically, the fan 14 is driven by the air inlet pipe 13 to draw in outside air, filter the air through the interception net 15, and finally blow into the inner tank 4, so as to dissipate heat for the transformer 44, and the hot air can be discharged through the filter net 11.
[0029] A conductive rod 2 is fixedly installed inside the bottom of the substation control room 1, a conductive block 21 is fixedly installed on the top of the conductive rod 2, a ground plug 22 is fixedly installed on the bottom of the conductive rod 2, an insulating tube 23 is fixedly installed on the middle outer side of the conductive rod 2, and a leakage alarm 24 is fixedly installed on one side of the conductive rod 2.
[0030] Specifically, the current in the inner tank 4 can be conducted through the conductive block 21, and then sent into the ground plug 22 from the conductive rod 2, and finally released into the ground through the ground plug 22. The leakage alarm 24 can sound an alarm when the conductive rod 2 conducts electricity.
[0031] A rain shelter 3 is fixedly installed on the top of the filter 11, an alarm device 31 is fixedly installed in the middle of the top of the rain shelter 3, a controller 32 is fixedly installed on the bottom of the alarm device 31, an infrared temperature detector 33 is fixedly installed in the middle of the bottom of the controller 32, a temperature sensor 34 is fixedly installed on one side of the controller 32, and a temperature detection device 35 is fixedly installed on the other side of the controller 32.
[0032] Specifically, the temperature is detected by attaching the temperature sensor 34 to the transformer 44, the temperature inside the inner tank 4 is detected by the temperature detection device 35, and the transformer 44 can be infrared-detected by the infrared temperature detector 33, thereby improving the practicality of the safety monitoring device of the substation equipment.
[0033] An inner liner 4 is fixedly installed inside the rubber layer 12 , and a humidity detector 41 is fixedly installed on one side inside the inner liner 4 .
[0034] An alarm device 42 is fixedly installed on one side of the humidity detector 41 , and a support frame 43 is fixedly installed on the inner bottom of the inner container 4 .
[0035] The top of the support frame 43 is movably connected with a transformer 44 .
[0036] Specifically, the humidity inside the inner tank 4 can be detected by the humidity detector 41. When the humidity is too high, an alarm is sounded by the alarm 42, and the transformer 44 is supported by the support frame 43, thereby improving the detection effect of the safety monitoring device of the substation equipment.
[0037] Working principle: First, the transformer 44 can be supported by the support frame 43. When the safety monitoring device of the substation equipment needs to dissipate heat, the operation of the fan 14 is driven by the inside of the air intake pipe 13, so that the outside air can be driven to enter the inside of the air intake pipe 13. The dust and impurities in the air can be intercepted by the interception net 15 inside the air intake pipe 13, so as to avoid the problem that dust and impurities enter the inside of the substation control room 1 and cause equipment short circuit, thereby improving the practicality of the safety monitoring device of the substation equipment. The air is blown into the inner tank 4 by driving the fan 14, and the bottom of the transformer 44 can be dissipated through the hole in the middle of the support frame 43. Through the shielding of the support frame 43, the air can be blown out from all sides to cool down the surroundings of the transformer 44. Finally, the hot air is discharged from the inside of the filter 11, thereby improving the heat dissipation effect of the safety monitoring device of the substation equipment. The humidity inside the inner tank 4 can be detected by the humidity detector 41. When the humidity is too high, an alarm is sounded by the alarm 42, thereby improving the safety monitoring device of the substation equipment. The practicability of the safety monitoring device of the substation equipment is improved. The rain canopy 3 can block rainwater. The temperature sensor 34 can be attached to the transformer 44 to detect the temperature of the transformer 44 in real time. The temperature detection device 35 can detect the temperature inside the inner tank 4. The infrared temperature detector 33 can detect the temperature of the transformer 44 by infrared. The three detection structures can improve the temperature detection effect of the safety monitoring device of the substation equipment, avoid the problem of the influence caused by the deviation of a single detection structure, and improve the practicability and accuracy of the safety monitoring device of the substation equipment. When the temperature is too high, the alarm device 31 can be controlled by the controller 32 to sound an alarm, thereby prompting that the temperature is too high. When a short circuit occurs, the current in the inner tank 4 can be led out through the conductive block 21 and sent from the conductive rod 2 to the inside of the ground plug 22, and finally the current is released to the ground through the ground plug 22. The leakage alarm 24 can sound an alarm when the conductive rod 2 is conducting, thereby improving the safety and practicability of the safety monitoring device of the substation equipment.
