Description

Technical Field

[0001] The present invention relates to the technical field of electric power equipment, and in particular to a modular intelligent box-type substation. Background Art

[0002] As we all know, traditional box-type substations include combined transformers and prefabricated substations. When an oil leak occurs in a transformer in a substation, the outflow of transformer oil will cause environmental pollution. Since the transformer is flammable, a fire is likely to occur when the transformer oil leaks. In addition, whether it is a combined transformer or a prefabricated substation, it is a completely unattended power distribution equipment. The status of various electrical equipment is out of the sight of managers for a long time. When an oil leak occurs in a substation, maintenance personnel cannot discover and repair it in time. If a fire occurs, it will have serious consequences and economic losses. Summary of the invention

[0012] Furthermore, the observation tube is made of transparent glass.

[0013] Further, the bottom end of the first conduit is close to the bottom end of the interior of the flame retardant tank.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the present invention provides a modular intelligent box-type substation with the following features:

[0016] Beneficial effects:

[0017] The modular intelligent box-type substation can detect whether the liquid level of the transformer oil inside the transformer drops by detecting the setting of the shell, resistance wire, float, paddle and connecting rod. When the liquid level drops, the float drives the paddle to drop, and the current detected by the ammeter changes. Therefore, when the current value detected by the ammeter changes, the warning light emits a flashing prompt light, and transmits a radio signal to the corresponding wireless receiving device through the signal generating device to prompt the maintenance personnel. The transformer oil can be collected by the setting of the storage tank and discharged into the interior of the flame retardant tank through the first conduit. Since the density of the transformer oil is less than the density of water, when the transformer oil enters the internal oil of the flame retardant tank, the oil floats on the water and flows into the interior of the storage tank. The water inside the flame retardant tank can isolate the transformer oil from the external environment to prevent the transformer oil from burning and causing a fire. The impurities in the transformer oil can be effectively precipitated at the bottom of the flame retardant tank through the process of the transformer oil rising in the water, so that clean transformer oil is stored in the storage tank.

Several support columns 7 are arranged on the top of the first fixed plate 6. The transformer is suspended to make the heat dissipation effect of the bottom of the transformer 9 better. The transformer 9 is arranged on the top of several support columns 7 to convert high voltage electricity into low voltage electricity.

A resistance wire 11 is arranged on the inner wall of the detection shell 10 to play the role of resistance. A paddle 14 is arranged inside the resistance wire 11. The sliding of the paddle 14 changes the conductive length of the resistance wire 11, thereby changing the current, which proves that the transformer When the liquid level of the transformer oil in the transformer 9 changes, a connecting rod 13 is provided at the bottom end of the paddle 14 to connect the float 12 and the paddle 14. A float 12 is provided at the bottom end of the connecting rod 13 to float on the top of the liquid level of the transformer oil.

The bottom of the left part of the first conduit 15 is located inside the flame retardant tank 16. A drain valve 18 is provided at the bottom of the front end of the flame retardant tank 16 to discharge impurities and moisture. A joint 19 is provided at the bottom of the left end of the flame retardant tank 16 to connect The observation tube 20 and the flame retardant tank 16 are provided at the top of the joint 19, which is convenient for observing the height of the liquid inside the flame retardant tank 16. A second conduit 22 is provided at the top of the right end of the flame retardant tank 16, which serves to connect the flame retardant tank 16 and the storage tank 29. The storage tank 29 is provided at the right part of the bottom end of the storage chamber 17, which serves to store transformer oil. The second conduit 22 is connected to the top of the left end of the storage tank 29. An oil drain valve 24 is provided at the bottom of the front end of the storage tank 29, which is convenient for discharging the transformer oil. An exhaust valve 23 is provided at the right part of the top of the storage tank 29 to discharge the gas inside the storage tank 29. A second fixing plate 28 is provided at the top of the low-voltage distribution room 4, which serves to fix and support the battery 25 and the ammeter 26.A battery 25 is provided at the left part of the top of the second fixed plate 28, which plays the role of providing electrical energy to the resistance wire 11. An ammeter 26 is provided at the right part of the top of the second fixed plate 28, which detects the current of the resistance wire 11 to prove whether the transformer oil has changed. The negative pole of the battery 25 and the paddle 14 are electrically connected through a wire, the positive pole of the battery 25 and the positive pole of the ammeter 26 are electrically connected through a wire, and the negative pole of the ammeter 26 and the resistance wire 11 are electrically connected through a wire. A warning light 27 is provided at the left part of the top of the waterproof cover 5, which emits a flashing light to remind the staff.

[0026] The outer wall of the observation tube 20 is provided with a scale 21 to facilitate calculation and recording of the height of the liquid inside the flame retardant tank 16 .

[0027] The flame retardant tank 16 is filled with clean water, the density of water is greater than the density of transformer oil, so that the transformer oil floats on the top of the water.

[0028] The highest mark of the scale 21 is arranged horizontally with the bottom end of the second conduit 22 , which serves as a reminder that maintenance personnel should keep a certain distance from the highest mark 21 when injecting water into the flame retardant tank 16 .

[0029] The bottom end of the storage tank 8 is inclined to facilitate the transformer oil to flow into the first conduit 15 .

[0030] The floating block 12 is made of polyurethane foam plastic, which has good buoyancy and can float above the liquid surface of the transformer oil.

[0031] The observation tube 20 is made of transparent glass, which is convenient for maintenance personnel to observe.

[0032] The bottom end of the first conduit 15 is close to the bottom end of the flame retardant tank 16, so that the transformer oil has a rising process to facilitate the precipitation of impurities in the transformer oil.

[0033] In summary, when the modular intelligent box-type substation is in use, the maintenance personnel inject transformer oil into the transformer 9 so that the float 12 floats above the liquid level of the transformer oil, and records the value displayed by the ammeter 26 at this time. The maintenance personnel then match the wireless receiving terminal and the wireless generator. When the transformer 9 leaks, the liquid level of the transformer oil drops, and the float 12 drives the connecting rod 13 and the paddle 14 to drop, changing the conductive length of the resistance wire 11. The value of the ammeter 26 changes, the warning light 27 emits a flashing light, and a radio signal is transmitted to the wireless terminal through the signal generator 30 to prompt the maintenance personnel. The leaked transformer oil flows into the storage tank 8, and then flows into the flame retardant tank 16 through the first conduit 15 and mixes with water. Since the density of the transformer oil is smaller than that of water, it floats above the water and flows into the storage tank 29. The water can have a good flame retardant effect to prevent the occurrence of fire, and the transformer 9 oil can precipitate impurities at the bottom of the water during the rising process.
