[0020] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0021] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0022] The following describes in detail, with reference to the accompanying drawings, the specific structure of an electric heat tracing control cabinet provided by this utility model and the corresponding technical effects it brings.

[0023] Please refer to Figures 1-2 The electric heat tracing control cabinet 1 provided in this embodiment of the utility model includes a cabinet 100. The cabinet 100 includes a power module area 110, a control module area 120 and a first terminal area 130 arranged sequentially at intervals. The power module area 110, the control module area 120 and the first terminal area 130 are arranged sequentially along the height direction of the cabinet 100, and the power module area 110 is located above the control module area 120.

[0024] Understandably, the partitioning of the cabinet 100 provided in this embodiment facilitates the separate wiring of components in different areas by operators, reducing the difficulty of wiring within the cabinet 100 and the maintenance difficulty for operators. Furthermore, the partitioning method arranged sequentially along the height direction in this embodiment also helps to achieve hierarchical management of wires and cables. The wires in the power module area 110 are usually thicker and carry larger currents. Concentrating them in the top power module area 110 can reduce the possibility of crossing with other signal lines and avoid interference.

[0025] Furthermore, each functional area has a clearly defined location, facilitating the planning and implementation of wiring paths. This ensures that every wire reaches its target location along the most direct path, reducing unnecessary bends and detours. Moreover, the partitioning of the power module area 110, control module area 120, and first terminal block area 130 within the cabinet 100 helps operators quickly locate fault points. For example, in the event of an electrical fault, one can first check whether the components in the power module area 110 are functioning properly, and then gradually investigate problems in the control module area 120 and the first terminal block area 130.

[0026] Electromagnetic interference (EMI) generated by the components within the power module area 110 can be effectively isolated by physical distance. Placing the power module area 110 at the top, away from the control module area 120 and the first terminal block area 130 located below the power module area 110, can significantly reduce the impact on sensitive electronic components and improve the stability of the electric heat tracing control cabinet 1.

[0027] Furthermore, by arranging the control module area 120 and the first terminal block area 130 at a relatively low position, operators can easily access the components within these areas without the need for ladders or footstools, improving work efficiency and reducing safety hazards. This also facilitates daily inspection and maintenance by operators.

[0028] In this embodiment, the power module area 110, the control module area 120 and the first terminal block area 130 are located on the front side of the cabinet 100. The first terminal block area 130 includes a power terminal block 131 for the electric heating cable.

[0029] Understandably, since the power module area 110, control module area 120 and first terminal block area 130 are located on the front side of the cabinet 100, it is convenient for operators to open the cabinet door 170 and observe the power module area 110, the first terminal block area 130 and the contents of the first terminal block area 130 in a timely manner, so as to facilitate the inspection and maintenance of the operators.

[0030] Understandably, the power terminal block 131 of the electric heating cable is used to connect the power line of the electric heating cable, and the first terminal block area 130 is located on the lower side of the cabinet 100 to facilitate the wiring of the power terminal block 131 of the electric heating cable by the operator.

[0031] Please refer to Figure 3 In this embodiment, the cabinet 100 also includes a second terminal block area 140, which is located on the left or right side of the cabinet 100. The second terminal block area 140 includes a sensor terminal block 141, and at least one of the sensor terminal block 141 and the power supply terminal block 131 of the electric heating cable is installed in the cabinet 100 by threaded fasteners.

[0032] In this embodiment, both the sensor terminal block 141 and the electric heating cable power terminal block 131 are installed on the cabinet 100 by threaded fasteners, so that the sensor terminal block 141 and the electric heating cable power terminal block 131 are stably installed on the cabinet 100.

[0033] In this embodiment, the second terminal block area 140 is located on the left side inside the cabinet 100, which helps to achieve zoned management of wires and cables. This layout allows sensor signal lines to be arranged separately from power lines, control lines, and other types of lines, reducing cross-interference and improving the electromagnetic compatibility of the electric heat tracing control cabinet 1.

[0034] Furthermore, the sensor terminal block 141 located on the left side inside the cabinet 100 can be centrally arranged to facilitate the planning and implementation of wiring paths, ensuring that each wire can reach the target location along the most direct path, reducing unnecessary bends and detours, thereby keeping the wiring neat and orderly.

[0035] Understandably, sensors are usually quite sensitive to temperature. Placing their terminal blocks away from heat sources (such as the power module area 110) can prevent the sensor's performance from being affected by excessively high ambient temperatures, ensuring that it can accurately sense and transmit data.

[0036] In detail, in this embodiment, the sensor terminal block 141 can be a PT100 sensor terminal block 141. It is understood that after the PT100 sensor on the electric heating tape is electrically connected to the PT100 sensor terminal block 141, the data acquisition controller 121 can be connected to the sensor, thereby allowing the generation of parameters by the data acquisition controller 121, such as alarm type, alarm temperature, and alarm hysteresis temperature. During operation, the electric heating control cabinet 1 will automatically start and stop the electric heating tape according to the set parameters. If operators encounter a fault, they can check the historical data of the data acquisition controller 121 to troubleshoot the fault and perform quick repairs.

[0037] Optionally, the electric heat tracing control cabinet 1 in this embodiment can also support RS485 communication. In case of a fault, the remote temperature data can be viewed remotely via RS-485 to determine the fault point.

[0038] Optionally, in this embodiment, the power module area 110 includes a circuit breaker 111, a surge protector 112, and an electric heating cable distribution switch 113. It is understood that the circuit breaker 111 can prevent overload and short circuits in the electric heating control cabinet 1. In this embodiment, the circuit breaker 111 is an incoming molded case circuit breaker 111. The surge protector 112 can protect the electric heating control cabinet 1 from surges, such as lightning strikes. The electric heating cable distribution switch 113 mainly provides independent control and protection for each electric heating cable circuit.

[0039] Of course, the power module area 110 may also include other components, not limited to circuit breaker 111, surge protector 112 and electric heating cable distribution switch 113.

[0040] Please continue to refer to this. Figure 2The control module area 120 includes a data acquisition controller 121, which can be understood as being used to collect sensor data and issue control signals according to preset logic to control the working status of the electric heating tape and other related equipment.

[0041] In this embodiment, the circuit breaker 111, surge protector 112, and electric heating cable distribution switch 113 are fixedly installed inside the cabinet 100 via a mounting base 115. This avoids directly installing the circuit breaker 111, surge protector 112, and electric heating cable distribution switch 113 inside the cabinet 100, thereby improving the installation stability of the circuit breaker 111, surge protector 112, and electric heating cable distribution switch 113 with the cabinet 100 and preventing loosening or detachment due to vibration or accidental collision, thus reducing the risk of electrical faults.

[0042] Understandably, mounting bracket 115 typically follows certain standard dimensions and interface designs, allowing circuit breakers 111, surge protectors 112, and distribution switches of different brands or models to be quickly and easily installed into the control cabinet.

[0043] In this embodiment, in order to improve the orderliness of cable laying in the cabinet 100, cable trays 150 are provided in the power module area 110, control module area 120 and first terminal area 130. The cable trays 150 in the power module area 110, control module area 120 and first terminal area 130 are arranged alternately. The cable trays 150 are used to lay cables so that the cable trays 150 are arranged in sections. Moreover, since the cable trays 150 in the power module area 110 and control module area 120 are arranged alternately, the high-voltage cables and low-voltage cables can be effectively isolated and laid, avoiding interference of the high-voltage cables to the electrical signals of the components in the control module area 120.

[0044] Optionally, in this embodiment, the electric heat tracing control cabinet 1 further includes a cooling fan 200. A vent 116 is provided on the top of the cabinet 100, and the cooling fan 200 is located at the vent 116 of the cabinet 100. An air inlet 174 is also provided on the lower side of the cabinet 100. Through the arrangement of the cooling fan 200 and the air inlet 174, an air duct can be formed inside the cabinet 100, thereby effectively improving the heat dissipation efficiency inside the cabinet. In addition, the power module area 110 is close to the vent 116, that is, the heat emitted by the power module area 110 can also be discharged from the vent 116 in a timely manner, which facilitates timely heat dissipation inside the electric heat tracing control cabinet 1.

[0045] In detail, a louver can be installed at the air inlet 174 to reduce the amount of external impurities entering the cabinet 100 from the air inlet 174.

[0046] The power module area 110 also includes a temperature controller 114, which is communicatively connected to the cooling fan 200. It can be understood that since the cooling fan 200 is located on the top of the cabinet 100, the temperature controller 114 in this embodiment is located inside the power module area 110 so that the temperature controller 114 can be electrically connected to the cooling fan 200.

[0047] Combination Figure 2 and refer to Figure 4 Of course, in order to ensure that the communication signal between the cooling fan 200 and the temperature controller 114 is not easily interfered with by the high-voltage components in the power module area 110, in some embodiments, corresponding shielding measures can also be set to shield the temperature controller 114 from interference by other components in the power module area 110.

[0048] Optionally, in this embodiment, the cabinet 100 includes a cabinet body 190 and a cabinet door 170 connected to each other. It should be noted that the power module area 110, control module area 120, first terminal block area 130 and second terminal block area 140 mentioned above are all located inside the cabinet body 190.

[0049] An observation window 173 is provided on the cabinet door 170, and an indicator light group 160 is provided inside the cabinet 100 opposite to the observation window 173. That is, the operator can observe the status of the indicator light group 160 inside the cabinet 100 through the observation window 173, so that the operator can judge the operating status inside the electric heat tracing control cabinet 1.

[0050] Please refer to the following for further information. Figure 1 In detail, in this embodiment, the air inlet 174 is provided on the cabinet door 170. Of course, in some other embodiments, the air inlet 174 can also be provided on the cabinet body 190.

[0051] Optionally, a file bag 172 is provided on the side of the cabinet door 170 near the cabinet body 100, so that the user can place the file bag 172 when opening the cabinet door 170.

[0052] Optionally, in some embodiments, in order to improve the strength of the cabinet door 170, the cabinet door 170 may also be provided with door panel reinforcing ribs 171.

[0053] Optionally, in order to reduce the impact of rainwater on the cabinet 100, a rain cover 180 can also be installed on the cabinet 100. Specifically, in this embodiment, a rain cover 180 is installed on the top of the cabinet 100, and a rain cover 180 can also be installed on the upper side of the cabinet door 170.

[0054] Optionally, in this embodiment, the cabinet 100 is further provided with a door limiter 300. Specifically, the door limiter 300 is located at the top of the cabinet 100 and close to the cabinet door 170. It can be understood that the door limiter 300 can be understood as a switching device used to detect the open / closed state of the cabinet door 170, so as to facilitate the detection of the real-time open / closed state of the cabinet door 170 of the cabinet 100.

[0055] Please continue to refer to this. Figure 4 Optionally, to facilitate operators to inspect the electric heat tracing control cabinet 1 in a dark environment, the cabinet 100 is also equipped with a lighting lamp 400. Specifically, the lighting lamp 400 is located on the top of the cabinet 100.

[0056] In summary, the electric heat tracing control cabinet 1 provided by this embodiment of the utility model includes a cabinet 100. The cabinet 100 includes a power module area 110, a control module area 120, and a first terminal block area 130 arranged sequentially at intervals. The power module area 110, the control module area 120, and the first terminal block area 130 are arranged sequentially along the height direction of the cabinet 100, with the power module area 110 located above the control module area 120. The partitioned layout within the cabinet 100 facilitates separate wiring for components in different areas by operators, reducing the difficulty of wiring within the cabinet 100 and also reducing the maintenance difficulty for operators.

[0057] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
