AI Technical Summary
The existing distribution cabinets do not have the function of cooling down the electrical components and wires, which can only cut off the power supply when the electrical components or wires continue to heat up, and cannot effectively prevent fires.
A distribution cabinet with protective function is designed, with a built-in fireproof mechanism, including a air guide duct, air outlet and a dry cold air blower. The cold air blown by the fan enters the inside of the meter through the air guide duct, cools down and processes electrical devices and wires, and contacts with the alarm through the expansion plate to issue a fire alarm.
By turning on the fan, the inside of the meter will be cooled down to avoid excessive temperatures causing fire or damage to electrical devices and wires. At the same time, the alarm mechanism will warn the personnel in advance to reduce unnecessary losses.

[0002] The distribution cabinet is a general term for the motor control center. The distribution cabinet is generally used to install various types of electricity meters. Various electrical components and wires are connected to the electricity meters. The electrical components will generate heat when working, and they will also generate heat when there is poor contact, which may burn the outer skin of the wires and cause a fire.
[0003] However, the existing power distribution cabinet does not have the function of cooling down the electrical components and wires. Therefore, when the electrical components or wires continue to heat up, the only option is to cut off the power supply and stop working to allow them to cool down naturally.

A fire prevention mechanism is arranged inside the protective shell, and the fire prevention mechanism is used to cool down the inside of the electric meter. An alarm mechanism is arranged on the upper left end of the rear side of the protective shell, and the alarm mechanism is used for fire alarm.
[0007] As a preferred technical solution of the utility model, the fire protection mechanism includes an air duct, an air outlet and a fan. The fan is connected to the inside of the lower side of the protective shell, the air duct is connected between the fan and the electric meter, and an air outlet is provided at the connection between the upper end of the air duct and the electric meter.
[0008] As a preferred technical solution of the utility model, the type of the fan is a dry cold air blower.
[0009] As a preferred technical solution of the utility model, the alarm mechanism includes a fixed plate, an expansion plate and an alarm. The fixed plate is connected to the upper rear side of the left side inside the protective shell, the expansion plate is connected to the right side of the fixed plate, and the alarm is connected to the upper left side of the rear side inside the protective shell.
[0010] As a preferred technical solution of the utility model, the expansion plate has the characteristics of thermal expansion and thermal contraction.
[0011] As a preferred technical solution of the utility model, it also includes a handle for opening and closing the protective door, and the front side of the protective door is connected with the handle.
[0012] Beneficial effects: 1. The utility model can turn on the fan to transport cold air to the inside of the meter through the air duct, cool down the electrical components and wires in the meter, keep them in a low temperature state, and avoid excessive temperature, fire or damage to the electrical components and wires.
[0013] 2. The utility model contacts the alarm through the expansion plate, causing the alarm to sound, which can warn people that the temperature in the protective shell is too high and a fire is about to occur, so that people can cool it down or put out the fire in time to reduce unnecessary losses.

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments. Example
[0021] A power distribution cabinet with protection function, such as Figure 1-Figure 4 As shown, it includes a protective shell 1, an electric meter 2, a protective door 3, a fire prevention mechanism 4 and an alarm mechanism 5. The electric meter 2 is fixedly connected to the rear side of the protective shell 1, and the protective door 3 is rotatably connected to the left front side of the protective shell 1. The protective door 3 prevents dust from entering the protective shell 1. The protective shell 1 is provided with a fire prevention mechanism 4, which is used to cool down the inside of the electric meter 2. The protective shell 1 is provided with an alarm mechanism 5 on the upper left end of the rear side, which is used for fire alarm to warn people.
[0022] like Figure 1-Figure 3 As shown, the fire protection mechanism 4 includes an air duct 41, an air outlet 42 and a fan 43. The fan 43 is fixedly connected to the lower side of the protective shell 1, the air duct 41 is connected between the fan 43 and the electric meter 2, and an air outlet 42 is provided at the connection between the upper end of the air duct 41 and the electric meter 2.
[0023] like Figure 3 As shown, the type of the fan 43 is a dry cold air blower.
[0024] When using the distribution cabinet with protection function, when the temperature of electrical components and wires in the electric meter 2 is overheated, the fan 43 can be turned on, and the cold air blown by the fan 43 enters the electric meter 2 from the air outlet 42 through the air duct 41, thereby cooling the electrical components and wires in the electric meter 2 to avoid fire or damage to the electrical components and wires due to excessive heating temperature. Example
[0025] On the basis of Example 1, Figure 1 , Figure 4 , Figure 5 As shown, the alarm mechanism 5 includes a fixed plate 51, an expansion plate 52 and an alarm 53. The fixed plate 51 is fixedly connected to the upper rear side of the left side inside the protective shell 1, the expansion plate 52 is connected to the right side of the fixed plate 51, and the alarm 53 is fixedly connected to the upper left side of the rear side inside the protective shell 1.
[0026] like Figure 1 , Figure 4 , Figure 5 As shown, the expansion plate 52 has the characteristic of thermal expansion and thermal contraction. When the temperature in the power distribution cabinet rises, the expansion plate 52 contacts the alarm 53.
[0027] When the temperature in the distribution cabinet is too high or a fire occurs, the expansion plate 52 expands and contacts the alarm 53 due to its thermal expansion and contraction characteristics. The alarm 53 sounds an alarm to warn people that the temperature in the protective shell 1 is too high and a fire is about to occur, so that people can cool it down or put out the fire in time to reduce unnecessary losses.
[0028] like Figure 1-Figure 4 As shown, a handle is also included for opening and closing the protective door 3, and the front side of the protective door 3 is fixedly connected with a handle.
[0029] When the electric meter needs to be repaired, people can hold the handle and turn it outward to open the protective door 3, which is convenient for repairing the electric meter.
