Description

Technical Field

[0001] The utility model relates to a switch cabinet, in particular to a temperature multi-dimensional monitoring switch cabinet with adjustable temperature sensitivity. Background Art

[0002] A switchgear is a type of electrical equipment. External wiring in the switchgear first enters the main control switch inside the switchgear, then flows into the sub-control switches. Each branch is configured as needed, such as for instruments, automatic controls, motor magnetic switches, and various AC contactors. Some switchgear also has high-voltage and low-voltage compartments, and is equipped with a high-voltage busbar, such as in power plants. Some also have low-frequency load shedding to protect key equipment.

[0003] Temperature rise design for switchgear is crucial for its long-term stable operation. Due to its small size and complex structure, switchgear components face poor heat dissipation, which can easily lead to excessive temperature rise. Excessive component temperatures can cause premature aging of equipment within the switchgear, resulting in equipment damage and power outages. A common approach to temperature rise design is temperature sensors.

[0004] When using a temperature sensor, it has a set heat dissipation temperature and a power-off temperature. When the switchgear temperature reaches the set temperature, the heat sink is controlled to cool the switchgear or to shut off the power for protection. The impact of temperature on the components in the switchgear changes with the use of the components. Therefore, if the switchgear is still used at the pre-set temperature value after long-term use, the components may be damaged before the heat sink operates. Conventional temperature sensors do not have a setting to change the setting. Utility Model Content

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] See also Figures 1 to 8 As an embodiment of the present invention, the temperature multi-dimensional monitoring switch cabinet with adjustable temperature sensitivity includes a cabinet body 1 and a cabinet door 101 rotatably mounted on the cabinet body 1; a heat-conducting tank body 2 is mounted on the cabinet door 101, and a liquid outlet 201 is provided on the heat-conducting tank body 2; a control ring 3 is rotatably mounted on the heat-conducting tank body 2; and a cooling fan 9 for cooling the cabinet body 1 is mounted on the cabinet door 101.

[0041] The cabinet door 101 is provided with an opening and closing mechanism for controlling the power on or off of the switch cabinet;

[0042] A guide rod 302 is mounted on the control ring 3, and a sliding sleeve 5 is slidably mounted on the guide rod 302. The control ring 3 is provided with a plurality of sensing mechanisms with different sensitivities, each of which can drive the sliding sleeve 5 on the guide rod 302 away from the control ring 3 according to temperature changes in the cabinet 1. When the sliding sleeve 5 slides to a set position, the cooling fan 9 is controlled to operate.

[0043] The sensing mechanism can control the working state of the opening and closing mechanism when driving the sliding sleeve 5 to slide to another set position;

[0044] The cabinet door 101 is also provided with a control mechanism for switching the sensitivity of the sensing mechanism.

[0045] In this embodiment, in the initial state, the cooling fan 9 does not work, and the opening and closing mechanism controls the switch cabinet to be in a power-on state; the heat-conducting tank 2 contains a heat-conducting liquid; as the switch cabinet continues to work, heat will accumulate inside the cabinet 1, and this heat will cause the heat-conducting liquid to expand due to the heat, thereby flowing out of the liquid outlet 201; the expanded heat-conducting liquid will drive the sensing mechanism to operate, thereby driving the sliding sleeve 5 away from the control ring 3; the temperature inside the cabinet 1 is different, and the expansion volume of the heat-conducting liquid will also be different. When the expansion of the heat-conducting liquid drives the sliding sleeve 5 to slide to a set position, the cooling fan 9 will be controlled to be powered on, so that the cooling fan 9 cools the cabinet 1, and when the sliding sleeve 5 slides to another set position, the opening and closing mechanism will be controlled to operate, so that the switch cabinet is immediately in a power-off state.

[0046] The control mechanism can switch sensing mechanisms with different sensitivities to cooperate with the expanding heat-conducting liquid, thereby changing the reaction rate of the sensing mechanism to the volume change of the heat-conducting liquid, thereby adapting to different working environments, thereby protecting the switch cabinet and improving the service life of the switch cabinet.

[0047] As a further solution of the present invention, the sensing mechanism includes a plurality of liquid outlet pipes 301 installed on the control ring 3 , a piston 4 is slidably fitted in the liquid outlet pipe 301 , and a connecting rod 401 connected to the sliding sleeve 5 is installed on the piston 4 .

[0048] In this embodiment, when the heat-conducting liquid expands due to heat and flows out of the liquid outlet 201, it will enter the liquid outlet pipe 301 corresponding to the liquid outlet 201, thereby pushing the piston 4 to slide in the direction away from the control ring 3, and pushing the sliding sleeve 5 away from the control ring 3 through the connecting rod 401; the temperature inside the cabinet 1 is different, the expansion volume of the heat-conducting liquid will also be different, and the distance the sliding sleeve 5 moves away from the control ring 3 will also be different.

[0049] The piston 4 senses the volume change of the heat-conducting liquid to drive the sliding sleeve 5 to move, which can respond to the temperature change in the cabinet 1 in a timely manner without any hysteresis, thereby improving the sensing efficiency of the sensing mechanism.

[0050] As a further solution of the present invention, the diameters of the plurality of liquid outlet pipes 301 are different, and the size of the piston 4 slidably connected thereto is changed accordingly.

[0051] In this embodiment, since the diameters of the liquid outlet pipes 301 are different, when the expansion volume of the heat-conducting liquid is the same, the strokes for pushing the piston 4 to slide are different (under the same temperature change, the smaller the cross-sectional area, the longer the flow length); by increasing or decreasing the diameter of the liquid outlet pipe 301 corresponding to the liquid outlet hole 201, the sensitivity of the sensing mechanism can be reduced or increased, so that the switch cabinet can adapt to different working environments and reduce the impact of the external environment on the switch cabinet.

[0052] As a further solution of the present invention, a matching block 10 is installed on the cabinet door 101 and is slidably matched with the outer wall of the sliding sleeve.

[0053] In this embodiment, when the sensing mechanism drives the sliding sleeve 5 to slide until it contacts the mating block 10, the cooling fan 9 is energized, causing it to rotate and cool the cabinet 1. The position where the sliding sleeve 5 and the mating block 10 first contact is the set operating position for the cooling fan 9. Because sensing mechanisms with different sensitivities produce different temperatures within the cabinet 1 when the sliding sleeve 5 contacts the mating block 10, by reducing or increasing the sensitivity of the sensing mechanism, the cooling fan 9 can be controlled to cool the cabinet 1 at different temperatures. This effectively protects the components within the switchgear and increases the service life of the switchgear.

[0054] As a further solution of the present invention, the opening and closing mechanism includes a fixed switch block 6 installed on the cabinet door 101, and a sliding switch block 7 slidably installed on the cabinet door 101 and capable of cooperating with the fixed switch block 6, a baffle 701 is installed on the sliding switch block 7, and a spring 8 is wrapped around the sliding switch block 7, the two ends of which respectively contact the sliding switch block 7 and the cabinet door 101; a limit plate 601 is rotatably installed on the fixed switch block 6 to cooperate with the sliding switch block 7.

[0055] In this embodiment, in the initial state, the sliding switch block 7 and the fixed switch block 6 are in conflict with each other, the spring 8 is in a compressed state, and the limit plate 601 is in conflict with the sliding switch block 7, so that the elastic force of the spring 8 always gives the baffle 701 a thrust, thereby causing the sliding switch block 7 to tend to separate from the fixed switch block 6. At this time, the switch cabinet is in a power-on state.

[0056] When the temperature inside the cabinet 1 rises, the sensing mechanism corresponding to the liquid outlet 201 drives the slider sleeve 5 to slide. As the temperature rises, the sliding travel of the sliding sleeve 5 increases. When the sliding sleeve 5 contacts the stop plate 601, the stop plate 601 rotates as the sliding sleeve 5 continues to slide. When the stop plate 601 rotates and separates from the sliding switch block 7, the spring 8 immediately separates the sliding switch block 7 from the fixed switch block 6, thereby de-energizing the switch cabinet. When the stop plate 601 separates from the sliding switch block 7, the sliding sleeve 5 is in the designated de-energized position for the switch cabinet.

[0057] The induction mechanism drives the sliding sleeve 5 to slide to the set position to control the working state of the opening and closing mechanism, thereby changing the power-on and power-off states of the switch cabinet, thereby protecting the components of the switch cabinet from being damaged by high temperature.

[0058] As a further solution of the present invention, the control mechanism includes a plurality of protrusions 304 installed on the outer wall of the control ring 3 for increasing the friction coefficient of the control ring 3.

[0059] In this embodiment, the control ring 3 is rotated by the boss 304 to change the liquid outlet pipe 301 corresponding to the liquid outlet hole 201, thereby increasing or decreasing the sensitivity of the sensing mechanism, so that the switch cabinet can adapt to different working environments, thereby increasing the service life of the switch cabinet.

[0060] As a further solution of the present invention, a telescopic sleeve 202 is installed on the heat-conducting tank body 2 , a positioning column 203 is slidably installed in the telescopic sleeve 202 , and a plurality of positioning holes 303 cooperating with the positioning column 203 are opened on the control ring 3 .

[0061] In this embodiment, when the control ring 3 is rotated, the control ring 3 will contact the positioning column 203, causing the positioning column 203 to slide inwardly in the telescopic sleeve 202; when the positioning hole 303 on the control ring 3 is rotated to just below the positioning column 203, the control ring 3 will disengage from the positioning column 203, causing the positioning column 203 to slide outwardly in the telescopic sleeve 202 under the action of gravity, causing the positioning column 203 to enter the positioning hole 303, thereby ensuring that each liquid outlet hole 201 is completely corresponding and conductive with the liquid outlet pipe 301.

[0062] As a further solution of the present invention, a rubber pad 11 is installed on the heat-conducting tank body 2, and a corresponding notch is opened on the control ring 3.

[0063] In this embodiment, the rubber pad 11 can increase the sealing performance of the heat-conducting tank body 2 and the control ring 3, thereby preventing leakage of the heat-conducting liquid at the connection between the two and causing the sensing mechanism to malfunction.

[0064] The above embodiments are exemplary rather than restrictive, so any technical solution of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention is included in the present invention.
