Description

Technical Field

[0001] The utility model belongs to the technical field of power distribution cabinets, and in particular relates to a power distribution cabinet with a temperature detection function. Background Art

[0002] Distribution cabinets (boxes) are classified as power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes). They are the final stage of the power distribution system. A distribution cabinet is a general term for motor control centers (MCCs). Distribution cabinets are used in applications with relatively dispersed loads and a small number of circuits, while MCCs are used in applications with concentrated loads and a large number of circuits. They distribute power from a circuit in the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the loads.

[0003] A variety of components are installed in the distribution cabinet and connected through lines. The components tend to generate a lot of heat during continuous operation. Since the interior of the distribution cabinet is a relatively closed environment, the heat is not easy to dissipate. It is also inconvenient for people to directly observe the temperature conditions inside the distribution cabinet, which can easily lead to damage to components and even safety accidents.

[0004] In order to solve the above problems, the utility model provides a power distribution cabinet with a temperature detection function.

[0005] The utility model is implemented as follows: a power distribution cabinet with a temperature detection function, including a cabinet body, a frame plate is vertically fixedly arranged in the cabinet body, a plurality of components are fixedly arranged on the frame plate, a plurality of shell mechanisms are arranged on the frame plate located on one side of the components, and the position of the temperature sensor is limited, the shell mechanism includes a first shell and a second shell, a plurality of first threaded holes are uniformly opened horizontally at the outer edge of the first shell, a plurality of second threaded holes are uniformly opened horizontally at the outer edge of the second shell, the positions of the first threaded holes and the second threaded holes correspond to each other and have the same aperture, bolts are arranged through the first threaded holes and the second threaded holes, and the first shell and the second shell are reliably connected together by the bolts,

[0006] A first through hole is horizontally opened in the middle of the first shell, a groove is opened in the middle of the first shell near one end of the second shell, the groove is connected to the first through hole, and one end of the temperature sensor is placed thereon, a second through hole is horizontally opened in the middle of the second shell, the second through hole corresponds to the position of the first through hole, a plurality of third through holes are horizontally opened on the shelf, the third through holes correspond to the position of the second through holes and have the same aperture, and the other end of the temperature sensor is placed thereon, a temperature sensor is arranged in the shell mechanism, the first through hole, the groove, the second through hole and the third through hole correspond to the position of the temperature sensor and have the same size At the same time, the position of the temperature sensor is limited and the temperature sensor is protected by the shell mechanism. The second shell is close to one end of the frame and is provided with an annular groove at the outer edge of the second through hole. A magnet is fixedly arranged in the annular groove. The shell mechanism and the frame can be reliably connected together through the adsorption effect of the magnet and the frame. A controller and an alarm are fixedly arranged on the outer wall of the cabinet. The controller is electrically connected to the temperature sensor and the alarm at the same time. The temperature sensor monitors the temperature in the distribution cabinet and transmits the result to the controller. When the temperature in the distribution cabinet exceeds the set value, the controller controls the alarm to sound an alarm, reminding people to dissipate heat from the distribution cabinet.

[0007] Preferably, the temperature sensor is a PT100 temperature sensor, which has the main characteristics of high measurement accuracy and stable performance.

[0008] Preferably, the aperture of the groove is larger than the apertures of the first through hole and the second through hole, thereby ensuring the limitation of the position of the temperature sensor.

[0009] Preferably, the center of the first through hole, the center of the groove, the center of the second through hole and the center of the third through hole are on the same straight line, ensuring that the temperature sensor passes through the first through hole, the groove, the second through hole and the third through hole smoothly.

[0010] The beneficial effects of the present utility model are as follows: the position of the temperature sensor is limited and protected by the shell mechanism; the shell mechanism and the frame plate are reliably connected together through the adsorption effect of the magnet stone and the frame plate, and the position of the shell mechanism can be easily changed according to needs; the temperature inside the cabinet is monitored by multiple temperature sensors, which can timely remind people to dissipate heat from the distribution cabinet.

The shell mechanism 4 includes a first shell 5 and a second shell 6. A plurality of first threaded holes 7 are uniformly opened horizontally at the outer edge of the first shell 5, and a plurality of second threaded holes 8 are uniformly opened horizontally at the outer edge of the second shell 6. The positions of the first threaded holes 7 and the second threaded holes 8 correspond to each other and have the same aperture. The first threaded holes 7 and the second threaded holes 8 are passed through the first threaded holes 7 and the second threaded holes 8. The second threaded hole 8 is provided with a bolt 9, which securely connects the first shell 5 and the second shell 6 together. A first through-hole 10 is horizontally provided in the middle of the first shell 5. A groove 11 is provided in the middle of the first shell 5 near one end of the second shell 6. The groove 11 is connected to the first through-hole 10 and is used to place one end of the temperature sensor 14. A second through-hole 12 is horizontally provided in the middle of the second shell 6. The second through-hole 12 corresponds to the position of the first through-hole 10. The diameter of the groove 11 is larger than the diameters of the first through-hole 10 and the second through-hole 12, ensuring the positioning of the temperature sensor 14. The frame 2 is horizontally provided with multiple third through-holes 13. The third through-holes 13 correspond to the position of the second through-hole 12 and have the same diameter.
