Description

Technical Field

[0001] The present invention belongs to the technical field of electric power, and in particular relates to an electrical equipment safety failure monitoring device capable of performing humidity detection. Background Art

[0002] When electrical equipment is used in a water supply environment, due to the high humidity of the external environment, it is necessary to monitor the humidity of the environment in which the electrical equipment is used to avoid the impact of humidity on the electrical equipment. However, when ordinary monitoring devices are used, in order to prevent water from affecting the electrical equipment, the heat dissipation of the internal equipment is insufficient. The monitoring body in the monitoring device is fixed to the connecting plate by bolts. The ordinary connection method is that the rear end of the monitoring body is fixed to the connecting plate by bolts, and the heat dissipation method is direct air blowing, so the heat dissipation effect on the rear side is not good. In addition, when the ordinary connecting plate is connected, a fixed screw will be inserted into the threaded connection hole, which will block the connecting screw hole, thereby affecting the cooling effect of the cold zone wind on the rear side of the component on the component, and ordinary monitoring equipment cannot meet the monitoring needs of different positions.

It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0026] Embodiment: An electrical equipment safety failure monitoring device capable of performing humidity detection

[0027] This embodiment discloses a device for monitoring the safety failure of electrical equipment capable of performing humidity detection. Figure 1-6 As shown, it includes a placement shell 1, which is installed inside the electrical equipment cabinet and detects the ambient humidity inside the electrical equipment cabinet. A connecting plate 10 is provided in the device shell 1, and the connecting plate 10 is used to install various components 13 in the monitoring body. The specific monitoring body adopts the existing monitoring mechanism on the market. A plurality of connecting holes 19 are spaced apart along the vertical direction on one end face of the connecting plate 10 close to the component 13. A cooling fan 12 is installed inside the device shell 1, and a ventilation pipe 14 facing the cooling fan 12 is coaxially connected in the connecting hole 19. The ventilation pipe 14 adopts heat dissipation material. A first connecting plate 20 is coaxially fixedly connected in the connecting hole 19. The first connecting plate 20 has a plurality of ventilation holes 24 distributed along its circumferential direction. The middle part of the first connecting plate 20 facing the components 13 close to the component 13 is detachably connected to the second connecting plate 22. The second connecting plate 22 and the component 13 are fixedly connected, and the monitoring body is electrically connected to the first humidity sensor 8. The first humidity sensor 8 is fixedly connected to the outside of the device shell 1. In this embodiment, the humidity on the outside of the shell 1 can be monitored through the first humidity sensor 8, and the monitoring data will be transmitted to the inside of the monitoring body for data processing; the cooling fan 12 draws external air and injects wind into the inside of the device shell 1 for heat dissipation. The wind flows into the connecting hole 19 through the ventilation pipe 14. Since the first connecting plate 20 and the ventilation hole 24 are provided, the wind can flow out from the ventilation hole 24 and blow air to dissipate heat to the component 13. Compared with the connection method in the prior art where the connecting plate 10 and the component 13 are directly fixed by bolts, the connecting hole 19 in this embodiment will not be blocked by the bolts, and the heat-dissipating wind will dissipate heat to the component 13 through the ventilation hole 24, and the heat dissipation effect is good.

[0028] The middle part of the second connecting plate 22 of this embodiment is fixedly connected with the screw 11, and the middle part of the first connecting plate 20 is provided with a threaded hole 23 threadedly connected to the screw 11. The two sides of the second connecting plate 22 are respectively inserted with first fixing bolts 21, and the first fixing bolts 21 are threadedly connected and fixed to the component 13. The ventilation hole 24 is arranged on the outside of the threaded hole 23, so that the fixed screw 11 will not completely block the connecting hole 19, so that the connecting hole 19 will also be ventilated while the screw 11 is inserted to blow air and cool the component 13 fixed on the front side through the second connecting plate 22, thereby greatly increasing the cooling efficiency of the component 13; specifically, the upper and lower sides of the second connecting plate 22 are respectively inserted with second fixing bolts 25, and the second fixing bolts 25 are threadedly connected to the threaded hole 23 of the first connecting plate 20 corresponding to it, thereby increasing the stability of the connection between the second connecting plate 22 and the connecting plate 10.

[0029] The device shell 1 of this embodiment is equipped with a cooling water supply shell 9, which is used to absorb the heat inside the device shell 1. The cooling water supply shell 9 is filled with cooling water. The cooling water supply shell 9 is an external water supply device, so that water can enter the interior of the cooling water supply shell 9, and the cooling water supply shell 9 adopts heat-absorbing materials on the market, so that the heat inside the device shell 1 can be absorbed, thereby achieving heat dissipation of the components 13; each ventilation pipe 14 is inserted into the interior of the cooling water supply shell 9, and one end of the ventilation pipe 14 is connected to the connecting hole 19, and the other end passes through the cooling water supply shell 9 and faces the cooling fan 12. Specifically, the ventilation pipe 14 is sealed with the side wall of the cooling water supply shell 9, and the wind blown out by the cooling fan 12 can absorb water when passing through the ventilation pipe 14. The cooling of the device shell 1 is achieved by cooling the air, thereby cooling the air and making the heat dissipation inside the device shell 1 more efficient; a water injection pipe 4 and a drainage pipe 5 connected to the interior of the cooling water supply shell 9 are respectively installed on the outside of the device shell 1, and the water injection pipe 4 can be connected to an external water supply device, so that water enters the interior of the cooling water supply shell 9, and the drainage pipe 5 can completely discharge the water inside the cooling water supply shell 9 as needed. A water outlet pipe 6 connected to the interior of the cooling water supply shell 9 is installed on the top of the device shell 1. The water outlet pipe 6 is the outlet of the water inside the cooling water supply shell 9. The water outlet is provided at the upper part, which can make the cooling water fill the inner cavity of the cooling water supply shell 9; a plurality of heat dissipation air outlets 3 are penetrated at intervals on the outside of the device shell 1, and an observation window 2 for observing the operation of the equipment inside the device shell 1 is installed on the outside of the device shell 1.

[0030] The side wall of the device housing 1 of this embodiment is penetrated with a fixing hole, and a connecting ring 7 is coaxially fixedly connected in the fixing hole. The outer wall of the first humidity sensor 8 and the inner wall of the connecting ring 7 are sealed with each other. The part of the first humidity sensor 8 located outside the device housing 1 is provided with a plurality of circular holes 18, which penetrate the side wall of the connecting ring 7. The circular holes 18 enable the connecting ring 7 to connect to the outside air, so that the first humidity sensor 8 can detect the external air humidity in real time. The part of the connecting ring 7 located outside the device housing 1 is threadedly connected with a conductor connecting sleeve 16. The upper and lower sides of the inner part of the conductor connecting sleeve 16 are made of conductor material, and the upper and lower sides of the outer side of the connecting ring 7 are respectively fixed. A conductor piece is fixedly connected, and the outer side of the conductor connecting sleeve 16 is electrically connected to the second humidity sensor 15 through a wire. By setting the conductor piece, when the connecting ring 7 is threadedly connected to the conductor connecting sleeve 16, the conductor piece is squeezed, so that the second humidity sensor 15 can be connected. The length of the wire of the second humidity sensor 15 can be set according to actual conditions, so as to meet the monitoring of humidity at different positions. The second humidity sensor 15 will transmit the monitored data to the inside of the monitoring body for data processing; the connecting ring 7 located outside the device shell 1 forms a limit ring 17 along its circumference, and the limit ring 17 is used to limit the position of the conductor connecting sleeve 16.
