Description

Terminal box for substation

technical field

The utility model relates to a terminal box for an electric power system, in particular to a terminal box for a substation.

Background technique

The terminal box is a common equipment in the substation. It is used for the connection of a large number of secondary wiring. It is necessary to ensure that the connecting terminals are free from moisture and corrosion. The secondary circuit was broken, causing an accident.

Utility model content

In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a terminal box for a substation, which can automatically adjust the temperature and humidity, and provide effective protection for the secondary connection terminal block.

In order to solve the above problems, the utility model adopts the following technical scheme: the terminal box for substation includes a box body, a convection fan is arranged in the box body, and several heat dissipation fans are arranged on the box body corresponding to the position of the convection fan Holes; an electric heater and a temperature and humidity sensor are also arranged in the box, and the temperature and humidity sensor, the electric heater, and the convection fan are all electrically connected to the general controller; a storage battery is also arranged in the box, and is connected to the general controller.

As a further technical solution of the utility model:

The terminal box for the substation also includes a solar panel, the solar panel is arranged on the top of the box, and a power conversion module, and the storage battery and the solar panel are connected to the general controller through the power conversion module.

The beneficial effects of the utility model are: it can maintain a suitable temperature and humidity, and can automatically adjust; in addition, it has the functions of rainproof and dustproof, and is suitable for use in substations.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

Fig. 1 is the structural representation of the utility model embodiment,

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the circuit principle block diagram of the utility model embodiment;

In the figure: 1 cabinet, 2 convection fan, 3 cooling holes, 4 electric heater, 5 temperature and humidity sensor, 6 master controller, 7 power conversion module, 8 battery, 9 solar panel.

Detailed ways

As shown in Figures 1 and 2, the substation terminal box includes a box body 1, and the box body 1 is provided with a convection fan 2, and a number of cooling holes 3 are provided on the box body 1 corresponding to the position of the convection fan 2 . An electric heater 4 and a temperature and humidity sensor 5 are also arranged in the box body 1 . As shown in FIG. 3 , the temperature and humidity sensor 5 , the electric heater 4 , and the convection fan 2 are all electrically connected to the master controller 6 . A solar battery panel 9 is arranged on the top of the box body 1 , and a battery 8 and a power conversion module 7 are also arranged in the box body 1 , and the battery 8 and the solar battery panel 9 are connected to the master controller 6 through the power conversion module 7 .

The general controller 6 is preset with temperature and humidity conditions. When working, the temperature and humidity detected by the temperature and humidity sensor 5 are converted into electrical signals and then transmitted to the master controller 6. The master controller 6 compares the signal with its internal preset temperature and humidity conditions to determine whether it is necessary to adjust the temperature and humidity. If the temperature and humidity in the terminal box need to be adjusted, the master controller drives the convection fan 2 and the electric heater 4 to work; if the temperature and humidity in the terminal box do not need to be adjusted, the convection fan 2 and the electric heater 4 do not work.

The accumulator 8 and the solar battery panel 9 of the terminal box for the substation can provide power for the general controller 6 alternatively. The power conversion module 7 controls and preferentially selects the solar cell panel 9 to supply power. If the solar cell panel 9 cannot meet the power supply conditions, the power conversion module 7 controls to connect the storage battery 8 for power supply.
