[0002] Thermal lightning is a type of lightning that often occurs in the afternoon in summer, often accompanied by heavy rain or hail. The following conditions must be met for thermal lightning to form: (1) The air is very humid and the water vapor in the air is nearly saturated, which is a necessary factor for the formation of thermal lightning; (2) The ground is exposed to the sun for a long time, and the temperature of the humid air close to the ground rises rapidly; (3) There is no wind or little wind, resulting in uneven air humidity and temperature; the above conditions gradually form clouds, and at the same time, the clouds form thunderclouds due to polarization, thus forming thunderstorm weather.

These abnormal phenomena will cause serious harm to the distribution cabinet and the electrical equipment therein, resulting in equipment damage and huge economic losses. In view of the adverse effects of thermal lightning on outdoor distribution cabinets caused by thunderstorm weather, this application provides a preventive lightning protection outdoor distribution cabinet to solve the above problems.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3The utility model provides a technical solution: a preventive lightning protection outdoor power distribution cabinet, including an outer shell 1 with a grounding wire at the bottom, an inner shell 3 embedded in the outer shell 1, and insulating rods 2 connected to the inner shell 3 are provided at both upper and lower ends of the outer shell 1, and an insulating shell protecting the inner shell 3 is provided in the gap between the outer shell 1 and the inner shell 3. The outer shell 1 is used to quickly conduct lightning current into the earth, thereby protecting the safe operation of the entire outdoor power distribution cabinet, avoiding equipment damage, and reducing economic losses.

[0018] The insulating shell includes an insulating sleeve 4 installed on the lower insulating rod 2 and an upper insulating plate 5 installed on the upper insulating rod 2. A slide groove is provided on the insulating sleeve 4, and an insulating plug plate 41 is slidably arranged inside the slide groove. An electric push rod 42 for driving the insulating plug plate 41 to move up and down is provided on the inner side of the insulating sleeve 4. When the electric push rod 42 works, the electric push rod 42 pushes the insulating plug plate 41 upward and makes the insulating plug plate 41 contact with the upper insulating plate 5.

[0019] A temperature and humidity sensor 8 is provided at the bottom edge of the upper insulating plate 5, a cooling fan 31 is installed in the mounting hole at the top of the inner shell 3, and evenly distributed cooling holes 6 are opened at the upper end of the side of the outer shell 1. During normal use, the insulating plug plate 41 is inserted into the slide groove of the insulating sleeve plate 4, and the temperature and humidity sensor 8 detects the temperature and humidity of the surrounding environment of the distribution cabinet through the cooling holes 6.

[0020] When the temperature and humidity sensor 8 detects that the temperature inside the power distribution cabinet is high, the heat dissipation fan 31 works for a period of time, and the heat dissipation fan 31 draws hot air inside the power distribution cabinet and discharges it through the heat dissipation holes 6.

[0021] A door panel is rotatably provided on the outer shell 1, and the door panel includes an outer door panel 7, an insulating door panel 71, an inner door panel 72 and an elastic member 73. The outer door panel 7 is rotatably provided on the outer shell 1, and the insulating door panel 71 is installed on the inner side of the outer door panel 7 through the elastic member 73, and the inner door panel 72 is installed on the inner side of the insulating door panel 71 through the elastic member 73. In thunderstorm weather, when the temperature and humidity sensor 8 detects that the humidity in the air is high, the electric push rod 42 works, and the electric push rod 42 pushes the insulating plug plate 41 upward, and makes the insulating plug plate 41 contact with the upper insulating plate 5. At this time, the insulating sleeve plate 4, the insulating plug plate 41, the upper insulating plate 5 and the insulating door panel 71 form a sealed cavity to insulate and seal the inner shell 3 for protection.

[0022] On rainy days, the insulating shell provides waterproof protection for the inner shell 3, so that rainwater can only slowly enter the gap between the outer shell 1 and the insulating shell through the heat dissipation holes 6, and be discharged through the gap between the outer shell 1 and the outer door panel 7.

[0023] Furthermore, the inner door panel 72 is used to block the cabinet opening of the inner shell 3 .

[0024] The cooling fan 31, electric push rod 42 and temperature and humidity sensor 8 used in the present invention are all commonly used electronic components in the prior art. Their working methods and circuit structures are well-known technologies and are not elaborated here. The cooling fan 31, electric push rod 42 and temperature and humidity sensor 8 are all electrically connected to the internal controller of the distribution cabinet.

[0025] When using:

[0026] During normal use, the insulating plug plate 41 is inserted into the slide groove of the insulating sleeve plate 4, and the temperature and humidity sensor 8 detects the temperature and humidity of the environment around the power distribution cabinet through the heat dissipation hole 6;

[0027] When the external air flows, the power distribution cabinet is cooled through the heat dissipation holes 6;

[0028] When the temperature and humidity sensor 8 detects that the temperature inside the power distribution cabinet is high, the cooling fan 31 works for a period of time, and the cooling fan 31 extracts the hot air inside the power distribution cabinet and discharges it through the cooling holes 6;

[0029] Before the occurrence of thunderstorm weather caused by thermal lightning, when the temperature and humidity sensor 8 detects that the humidity and temperature in the air have reached a certain value, the external controller controls the electric push rod 42 to work, and the electric push rod 42 pushes the insulating plug plate 41 upward, and makes the insulating plug plate 41 contact with the upper insulating plate 5. At this time, the insulating sleeve plate 4, the insulating plug plate 41, the upper insulating plate 5 and the insulating door plate 71 form a sealed cavity to insulate and seal the inner shell 3 for protection;

[0030] When lightning strikes the outer shell 1, the outer shell 1 quickly conducts the lightning current into the ground through the grounding wire at the bottom thereof, thereby protecting the safe operation of the entire outdoor power distribution cabinet.

[0031] The utility model can detect the temperature and humidity of the environment around the power distribution cabinet, and timely insulate and protect the inner shell 3 and the electrical equipment inside it, and can quickly conduct the lightning current into the earth through the grounded outer shell 1, thereby protecting the safe operation of the entire outdoor power distribution cabinet, avoiding equipment damage, thereby reducing economic losses, and being easy to use.
