Description
Technical Field
[0001] The invention relates to the technical field of power cabinet accessories, and in particular to an installation structure for an anti-condensation device of a high- and low-voltage power cabinet. Background Art
[0002] When the high and low voltage power cabinets are in operation, due to the large number of electrical components in the cabinets, more heat is generated during operation, resulting in a certain temperature difference between the cabinet and the outside world. Especially in autumn and winter, condensation will occur on the side walls of the high and low voltage power cabinets. Under the action of tension and gravity, the condensation will gradually gather into large water droplets and drip onto the components in the cabinet, which may easily lead to serious consequences such as failure or burning of electrical components and tripping of switchgear. Therefore, anti-condensation devices are often installed inside high and low voltage power cabinets for dehumidification.
[0003] Anti-condensation devices for power cabinets are generally pasted inside the cabinet with adhesive paper, or installed on the side wall with bolts. Since the current anti-condensation devices generally absorb water vapor in the cabinet through water-absorbing parts such as hydrophilic cotton or dehumidifying particles, although they can prevent the formation of large water droplets, they cannot prevent the formation of tiny condensation on the cabinet wall, and the water absorption performance of the water-absorbing parts will gradually decrease. If they are not replaced in time, the adhesive backing and assembly bolts of the anti-condensation device will often be in a humid environment, resulting in an unstable installation structure of the anti-condensation device itself. Therefore, an installation structure of an anti-condensation device for high and low voltage power cabinets is proposed. Summary of the invention
[0004] The purpose of the present invention is to solve the problem that the current anti-condensation device generally absorbs water vapor in the cabinet through water-absorbing parts such as hydrophilic cotton or dehumidification particles.

If they cannot be replaced in time, the back glue and assembly bolts of the anti-condensation device will often be in a humid environment, resulting in an unstable installation structure of the anti-condensation device itself.

At the same time, the hot air circulates and cools between the top and bottom of the anti-drip shed, reducing the impact of the anti-condensation heater heating the cabinet wall on the temperature in the cabinet;
[0020] 6. The present invention provides a leakproof rubber cover so that when the circulating fan delivers hot air to the top of the anti-drip shed through the circulating air duct, the wind force will slightly lift up one side of the leakproof rubber cover, and the leakproof rubber cover will always remain at the top of the circulating air duct to shield the circulating air duct, thereby realizing one-way connection of the circulating air duct, thereby preventing dust or condensation inside the top plate from directly passing through the circulating air duct into the interior of the power cabinet;

The present invention provides an outer cable bundle tube so that the outer cable bundle tube can protect the transmission cable inside, distinguish and isolate the transmission cable from other lines in the power cabinet, and at the same time, the outer cable bundle tube can be bent according to the distribution of circuit breakers, relay instruments, control electrical appliances and other lines and electrical appliances inside the power cabinet, so that the direction of the transmission cable is fixed and more suitable for the arrangement inside the power cabinet;
[0023] 9. The present invention sets up micro fans so that the cabinet wall temperature closest to the thermal buckle plate is the highest, which in turn causes the air temperature nearby to rise. The micro fans distributed on one side of each thermal buckle plate can transport and disturb the air near the thermal buckle plate, thereby accelerating the air flow inside the power cabinet, making the air temperature inside the power cabinet more uniform and avoiding heat concentration.

Figure 1 As shown, the tops of the multiple heat-conducting buckle plates 1 are provided with the same anti-drip shelf plate 9. In this embodiment, the heat-conducting buckle plates 1, the heating plate 7, the heat-conducting seat 8, the anti-drip shelf plate 9, etc. are all made of metal materials. The four corners of the bottom of the anti-drip shelf plate 9 are fixedly installed with mounting angle plates 10. The side walls of the mounting angle plates 10, the heat-conducting buckle plates 1 and the mounting back plate 2 are all provided with multiple bolt assembly holes 1001, such as Figure 6As shown, a sealing strip 11 is fixedly installed on the top of the anti-drip shelf 9. In this embodiment, the heat conductive buckle plate 1 is fixedly installed on multiple inner walls of the power cabinet, the anti-condensation heater 3 is installed inside the power cabinet through the mounting back plate 2, the anti-drip shelf 9 is installed on the inner wall of the top of the power cabinet, the outer dimension of the sealing strip 11 is slightly larger than the outer dimension of the anti-drip shelf 9, the sealing strip 11 is located on the top of the anti-drip shelf 9 and contacts the cabinet wall of the power cabinet. After the installation structure is assembled inside the power cabinet, a water absorption anti-condensation device can be further installed, and a temperature sensor can be installed on the inner wall of each side of the power cabinet to monitor the cabinet wall temperature of the power cabinet in real time;Specifically, when installing the anti-condensation device installation structure of the high and low voltage power cabinet, first, the positioning blocks 5 at one end of the multiple transmission cables 4 are sequentially placed in the positioning seats 6 in each heat-conducting buckle plate 1, so that the heating plate 7 is in close contact with the heat-conducting seat 8, and then the fastening bolts are screwed with the positioning holes 501 and the threaded holes on the positioning seat 6 to fix the heating plate 7 inside the heat-conducting buckle plate 1, and then a corresponding number of threaded holes are punched at designated positions on the inner wall of the power cabinet, and then each heat-conducting buckle plate 1 is sequentially placed between the circuit breaker, relay instrument, control electrical appliance, distributor, busbar room, etc. inside the power cabinet, so that the side of the heat-conducting buckle plate 1 is in close contact with the heat-conducting buckle plate 1. The cabinet wall is attached, and then the bolt assembly holes 1001 on the thermal buckle plate 1 and the threaded holes on the power cabinet are screwed with fastening bolts in turn, and multiple thermal buckle plates 1 are installed inside the power cabinet. Then, the mounting back plate 2 together with the anti-condensation heater 3 are screwed inside the power cabinet, and finally the anti-drip shelf 9 is screwed to the inner wall of the top of the power cabinet to complete the assembly of the anti-condensation device and the mounting structure. By setting the anti-condensation heater 3, the anti-condensation heater 3 controls the heating plate 7 to heat through the power transmission cable 4, so that the thermal seat 8 attached to the heating plate 7 is heated together with the thermal buckle plate 1, thereby heating the surrounding power. The side walls of the cabinet are heated so that the cabinet wall temperature of the power cabinet is close to or even slightly exceeds the air temperature inside the cabinet, thereby effectively preventing moisture in the air inside the cabinet from condensing on the cabinet wall, thereby fundamentally avoiding the occurrence of condensation on the cabinet wall. The installation structure is assembled by means of bolt assembly holes 1001 on the thermal buckle plate 1, the installation back plate 2 and the anti-drip shelf plate 9 in combination with fastening bolts. Compared with the commonly used adhesive surface fixing method, the installation structure is more tight and stable. At the same time, the anti-condensation heater 3 heats the cabinet wall, fundamentally avoiding the generation of condensation, so that the fastening bolts connected to the cabinet wall are always kept dry. In an environment, the bolts can be effectively prevented from rusting and loosening due to humid air. By setting the anti-drip shed 9, after the anti-drip shed 9 is installed, various circuits and electrical appliances inside the power cabinet will generate more heat during operation. At the same time, the anti-condensation heater 3 heats the cabinet wall, so that the hot air in the cabinet will surge upward and contact the cabinet wall at the top, thereby generating a certain amount of condensation. The anti-drip shed 9 at the top can isolate the condensation. The sealing strip 11 at the top of the anti-drip shed 9 will contact the cabinet walls on the four sides, thereby improving the sealing of the anti-drip shed 9 and preventing the condensation on the top of the cabinet from falling. ;

[0043] like Figure 5 As shown, the transmission cables 4 are all sleeved with sealing rubber sleeves 17, and the multiple sealing rubber sleeves 17 are respectively located inside the multiple give-way grooves 101; specifically, by setting the sealing rubber sleeves 17, when the heating plate 7 is installed, the sealing rubber sleeves 17 are clamped in the give-way groove 101 on the heat-conducting buckle plate 1, and as the heat-conducting buckle plate 1 is screwed and fixed, the sealing rubber sleeves 17 will be squeezed and fixed between the heat-conducting buckle plate 1 and the cabinet wall, so that the sealing rubber sleeves 17 block the give-way groove 101, and cooperate with the heat insulation layer on the side of the heat-conducting buckle plate 1 to play a heat insulation role, so that the heat-conducting buckle plate 1 heats the cabinet wall instead of directly heating the air inside the power cabinet.
[0044] like Figure 3 As shown, the transmission cables 4 are all sleeved with outer cable bundle tubes 18, such as Figure 8 As shown, the outer sheath wire harness tube 18 includes multiple folding wire harness tubes 1801 and multiple reversing hoses 1802, and the folding wire harness tubes 1801 and the reversing hoses 1802 are both sleeved on the transmission cable 4, and the multiple reversing hoses 1802 are respectively fixedly installed between any two adjacent folding wire harness tubes 1801 and between the folding wire harness tube 1801 and the sealing rubber sleeve 17. In this embodiment, the folding wire harness tube 1801 can be fixed to the cabinet wall by means of wire clamps and bolts; specifically, by setting the outer sheath wire harness tube 18, the outer sheath wire harness tube 18 composed of multiple sections of folding wire harness tubes 1801 and reversing hoses 1802 of different lengths can protect the transmission cable 4 inside, distinguish and isolate the transmission cable 4 from other lines in the power cabinet, and at the same time, the outer sheath wire harness tube 18 can be bent according to the distribution of lines and electrical appliances such as circuit breakers, relay instruments, and control electrical appliances inside the power cabinet, so that the direction of the transmission cable 4 is fixed and more adapted to the arrangement inside the power cabinet.

[0046] In summary: the installation process of this installation structure is as follows: first, place the positioning blocks 5 at one end of multiple transmission cables 4 into the positioning seats 6 in each heat-conducting buckle plate 1 in turn, clamp the sealing rubber sleeve 17 into the clearance groove 101 on the heat-conducting buckle plate 1, so that the heating plate 7 is in close contact with the heat-conducting seat 8, and then use the fastening bolts to screw with the positioning holes 501 and the threaded holes on the positioning seat 6 to fix the heating plate 7 inside the heat-conducting buckle plate 1, then punch a corresponding number of threaded holes at designated positions on the inner wall of the power cabinet, and then place each heat-conducting buckle plate 1 in turn between the circuit breaker, relay instrument, control electrical appliance, distributor, busbar room, etc. inside the power cabinet , make the side of the heat-conducting buckle plate 1 stick to the cabinet wall, then screw the fastening bolts in the bolt assembly holes 1001 on the heat-conducting buckle plate 1 and the threaded holes on the power cabinet in turn, install multiple heat-conducting buckle plates 1 inside the power cabinet, as the heat-conducting buckle plates 1 are screwed and fixed, the sealing rubber sleeve 17 will be squeezed and fixed between the heat-conducting buckle plate 1 and the cabinet wall, then screw the installation back plate 2 together with the anti-condensation heater 3 inside the power cabinet, and finally screw the anti-drip shelf 9 to the inner wall of the top of the power cabinet, install the heat-conducting rod 12 between the heat-conducting buckle plate 1 and the anti-drip shelf 9 by fastening bolts, and complete the assembly of the anti-condensation device and the installation structure;
[0047] Operation of the anti-condensation device: The anti-condensation heater 3 controls the heating plate 7 to heat up through the power transmission cable 4, so that the heat-conducting seat 8 attached to the heating plate 7 and the heat-conducting buckle plate 1 are heated together, and then the surrounding side walls of the power cabinet are heated, so that the cabinet wall temperature of the power cabinet is close to or even slightly exceeds the temperature inside the cabinet, thereby effectively preventing the moisture in the air inside the cabinet from condensing on the cabinet wall, thereby fundamentally avoiding the occurrence of condensation on the cabinet wall. Various circuits and electrical appliances inside the power cabinet will generate more heat when operating, and the anti-condensation heater 3 will heat the cabinet wall at the same time. , so that the hot air in the cabinet will surge upward and then contact the cabinet wall at the top, thereby generating a certain amount of condensation. The anti-drip shelf 9 at the top can isolate the condensation. The sealing strip 11 on the top of the anti-drip shelf 9 will contact the cabinet walls on the four sides, thereby improving the sealing performance of the anti-drip shelf 9 and preventing the condensation on the top of the cabinet from falling. The heated heat-conducting buckle plate 1 can heat the bottom of the anti-drip shelf 9 through the heat-conducting rod 12, thereby heating the anti-drip shelf 9, greatly reducing the condensation generated on the anti-drip shelf 9 after the hot air inside the power cabinet surges upward, thereby improving The anti-drip shelf 9 has an anti-condensation function. When the power cabinet is operating normally, the circulating fan 13 at the bottom of the anti-drip shelf 9 will start to operate, and the hot air inside the power cabinet will be sent into the space between the anti-drip shelf 9 and the top plate of the power cabinet, and then return to the inside of the power cabinet through the multiple circulating air holes 1002 at the bottom of the anti-drip shelf 9, so that the hot air delivered by the circulating fan 13 heats the other side of the anti-drip shelf 9 and the top plate of the power cabinet, further reducing the generation of condensation, and at the same time, the hot air circulates and cools between the top and bottom of the anti-drip shelf 9, and The sealing rubber sleeve 17 seals the give way groove 101, and cooperates with the heat insulation layer on the side of the heat conductive buckle plate 1 to play a heat insulating role, so that the heat conductive buckle plate 1 heats the cabinet wall, but does not directly heat the air inside the power cabinet. The micro fans 20 respectively distributed on one side of each heat conductive buckle plate 1 can transport and disturb the air near the heat conductive buckle plate 1, accelerate the air flow inside the power cabinet, make the temperature inside the power cabinet more uniform, avoid heat concentration, and reduce the impact of the anti-condensation heater 3 heating the cabinet wall on the temperature inside the cabinet;
[0048] Function of this installation structure: It is assembled by means of bolt assembly holes 1001 on the thermal buckle plate 1, the mounting back plate 2 and the anti-drip shelf plate 9 in combination with the fastening bolts. Compared with the commonly used adhesive surface fixing method, this installation structure is tighter and more stable. At the same time, the anti-condensation heater 3 heats the cabinet wall, fundamentally avoiding the generation of condensation, so that the fastening bolts connected to the cabinet wall are always kept in a dry environment, effectively preventing the bolts from rusting and loosening due to humid air.
