Description

Technical Field

[0001] The utility model relates to the field of high temperature alarms for power distribution cabinets, in particular to a high temperature alarm for power distribution cabinets. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in the occasions where the load is relatively dispersed and there are fewer circuits; the motor control center is used in the occasions where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load;

[0003] For example, a high-temperature protected vertical distribution cabinet disclosed in the utility model with authorization announcement number CN209016516U wraps its inner wall with a rubber plate so that when external force acts, its internal components will only contact part of the force, and then fix the rubber column, shock-absorbing pad and spring inside the base through a connecting plate, and then the rubber column, shock-absorbing pad and spring are used to reduce shock, so that its internal components are not easy to loosen or fall off, thereby achieving the effect of convenient use. However, most of the current distribution cabinets do not have a high-temperature alarm structure themselves, so when a high temperature is generated inside the distribution cabinet, it is difficult for the operator to discover it at the first time, which will cause the internal parts of the distribution cabinet to be damaged due to the high temperature, affecting the normal operation of the subsequent distribution cabinet and causing unnecessary trouble.

[0022] When in use, the internal structure of the cabinet 1 can be inspected and repaired by rotating the cabinet door 2. When the internal temperature of the cabinet 1 rises to a certain temperature, the high temperature will cause the thermal fuse 8 to break, and then the power storage board 9 will move longitudinally and push the contact pad 10 to contact the conductive seat 13 to achieve current connection. After the current is connected, the alarm 3 will work normally, and then an alarm will be sounded to remind the staff that high temperature is generated inside the cabinet 1.

[0023] As a further implementation of this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an alarm 3 is fixedly installed on the inner wall of the cabinet 1, and a wire 4 is fixedly connected to the bottom of the alarm 3, one end of the wire 4 passes through the top of the fixed frame 5 and is electrically connected to the conductive seat 13, and the fixed frame 5 is symmetrically distributed along the vertical center line of the cabinet 1, a fixed frame 5 is distributed below the alarm 3, and a through hole 6 is opened at the bottom of the fixed frame 5, a honeycomb panel 7 is arranged on the inner side of the bottom of the fixed frame 5, and a thermal fuse 8 is fixedly connected to the middle of the top of the honeycomb panel 7, the other end of the thermal fuse 8 is fixedly connected to a power storage board 9, and a contact pad 10 is fixedly arranged in the middle of the top of the power storage board 9, an internal power supply is arranged inside the power storage board 9, which is convenient for providing power for the alarm 3 later, the power storage board 9 is slidably connected to the guide frame 12 through a reset spring 11, and the reset spring 11 is symmetrically distributed along the vertical center line of the power storage board 9, The positioning spring 11 itself is in a stretched state, a reset spring 11 is fixedly connected to one side of the top of the power storage board 9, a guide frame 12 is fixedly installed on the inner side wall of the fixed frame 5, a conductive seat 13 is fixedly installed on the inner top of the fixed frame 5, a connecting structure is arranged on the inner side of the bottom of the cabinet 1, a ventilation cavity 14 is opened on the inner side of the bottom of the cabinet 1, and an air outlet groove 15 is connected to the top of one side of the ventilation cavity 14, and an air inlet groove 16 is connected to the other side of the ventilation cavity 14, the air inlet groove 16 is distributed in a honeycomb shape on one side of the bottom of the cabinet 1, and the air inlet groove 16 and the cabinet 1 are an integrated structure, the ventilation cavity 14, the air outlet groove 15 and the air inlet groove 16 form a connecting structure, and the connecting structure is located on the inner side of the bottom of the cabinet 1, an exhaust fan 17 is arranged on the inner side of the ventilation cavity 14, and an adsorption carbon plate 18 is distributed on one side of the exhaust fan 17, and a filter cotton plate 19 is distributed on the side of the adsorption carbon plate 18 away from the exhaust fan 17;

[0024] When high temperature is generated inside the cabinet 1, the generated high temperature will enter the inner side of the fixing frame 5 through the through hole 6 opened at the bottom of the fixing frame 5, and the impurities and other particulates in the circulating air can be effectively removed by using the honeycomb panel 7. At the same time, when the temperature inside the fixing frame 5 rises to a certain level, the thermal fuse 8 will break due to its low melting point, and since the reset spring 11 is always in a stretched state before the thermal fuse 8 breaks, when the thermal fuse 8 breaks, the reset spring 11 retracts and drives the power storage board 9 to move longitudinally. At the same time, when the power storage board 9 moves longitudinally, it will move longitudinally along the guide frame 12, thereby improving the stability of the power storage board 9 during the longitudinal movement, and the power storage board 9 can move longitudinally. The movement will push the contact pad 10, and then the contact pad 10 will contact the conductive seat 13 to achieve circuit connectivity, and then the power of the power storage board 9 will be transmitted to the alarm 3 through the wire 4, so as to realize the operation of the alarm 3, so as to remind the staff that the internal temperature of the cabinet 1 is too high, and achieve the purpose of high temperature alarm.

[0025] Specific working principle:

[0026] When in use, the internal structure of the cabinet 1 can be inspected and repaired by rotating the door 2.

At the same time, when the temperature inside the fixed frame 5 rises to a certain level, the thermal fuse 8 will break due to its low melting point, and the reset spring 11 is always in a stretched state before the thermal fuse 8 breaks. Therefore, when the thermal fuse 8 breaks, the reset spring 11 retracts and drives the power storage board 9 to move longitudinally. At the same time, the power storage board 9 will move longitudinally along the guide frame 12 when moving longitudinally, thereby improving the longitudinal movement of the power storage board 9. To ensure the stability of the process, the power storage board 9 will push the contact pad 10 while moving longitudinally, and then the contact pad 10 will contact the conductive seat 13 to realize the connection of the circuit, and then the power of the power storage board 9 will be transmitted to the alarm 3 through the wire 4, so as to realize the operation of the alarm 3, so as to remind the staff that the internal temperature of the cabinet 1 is too high, so as to achieve the purpose of high temperature alarm. At the same time, when the internal temperature of the cabinet 1 is too high, the exhaust fan 17 will work, and the external air will be drawn into the inner side of the ventilation cavity 14 through the air inlet groove 16, and filtered and adsorbed by the provided adsorption carbon plate 18 and the filter cotton plate 19, so as to effectively remove the impurities and other particulates mixed in the air, and the treated air will be discharged through the air outlet groove 15, so as to effectively cool the interior of the cabinet 1.
