Description
Technical Field
The utility model belongs to the electrical field especially relates to a high-voltage board.
Background
The high-voltage switch cabinet is used for controlling the power utilization of different areas. High-voltage cabinets are generally provided with circuit mounting structures, such as circuit breakers, to prevent the danger of burning out electrical components in the high-voltage cabinet due to excessive current. However, the current of the electrical appliances such as an air conditioner, a refrigerator, a television and the like is maximum at the moment of starting, and then is rapidly reduced to the level of keeping running, the reason for damaging the electrical elements in the high-voltage cabinet is continuous large current, the electrical elements are further overheated and burnt, and the instantaneous large current cannot cause damage. However, the existing high-voltage cabinet protection devices detect instantaneous current, and power failure is performed once the current exceeds a set threshold value, which may cause instantaneous power failure of the high-voltage cabinet protection device at the moment when a user turns on a certain electric appliance. Especially, when power is cut off in a community and then power is supplied, a large number of electric appliances are instantly started at the same time, so that current is instantly overlarge, and the high-voltage board protection device is instantly powered off, so that repeated starting of the high-voltage board and resident electric appliances can only prevent the high-voltage board protection device from instantly powering off the high-voltage board by gradually starting the corresponding power utilization switches of one unit of users in the community by workers. In addition, the high-voltage board generates more heat, but current high-voltage board all is a fan of installation from top to bottom directly-blown, causes that the one side of components and parts leeward can not in time dispel the heat just, and the wind-force that the components and parts far away from the fan received is little, and the temperature of wind is high, and the heat dissipation is relatively poor.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a high-voltage board. The utility model discloses simple structure, convenient to use corresponds every electric elements through the rectangle pipeline, has guaranteed that the electric elements far away from the exhaust fan also can effectively cool down, and realizes special cooling through the through-hole to electric elements and electric wire, has effectively improved the efficiency of seeing and hearing of high-voltage board, has prevented the circuit confusion in the high-voltage board simultaneously.
In order to achieve the above technical effects, the technical scheme of the utility model is that:
a control transformer of a high-voltage cabinet is electrically connected with a circuit breaker, the circuit breaker is electrically connected with a timer, and the timer is electrically connected with an ammeter; the control transformer, the circuit breaker, the timer and the ammeter are all arranged in the cabinet body; an air cooler is installed at the top of the cabinet body, a plurality of rectangular pipes are installed in the cabinet body, and a plurality of air exhaust holes are formed in the upper surface and the lower surface of each rectangular pipe; one end of the rectangular tube is closed, and the other end of the rectangular tube is communicated with the air cooler.
In a further improvement, the rectangular tubes are arranged transversely.
In a further improvement, the air cooler is communicated with all the rectangular pipes through communicating pipes.
In a further improvement, the bottom of the cabinet body is provided with a support leg.
In a further improvement, the legs are L-shaped.

FIG. 1 is a schematic view of the internal structure of the present patent;
fig. 2 is a schematic structural view of a rectangular tube.
Detailed Description
The technical solution of the present invention will be described in detail with reference to the following embodiments and accompanying drawings.
Example 1
The high-voltage cabinet is shown in figures 1 and 2, a control transformer 1 of the high-voltage cabinet is electrically connected with a circuit breaker 2, the circuit breaker 2 is electrically connected with a timer 3, and the timer 3 is electrically connected with an ammeter 4; the control transformer 1, the circuit breaker 2, the timer 3 and the ammeter 4 are all arranged in the cabinet body 5; an air cooler 6 is installed at the top of the cabinet body 5, a plurality of rectangular pipes 7 are installed in the cabinet body 5, and a plurality of air exhaust holes 8 are formed in the upper surface and the lower surface of each rectangular pipe 7; one end of the rectangular tube 7 is closed, and the other end is communicated with the air cooler 6.
The principle of the utility model is as follows: the ammeter 4 is used for detecting and recording the instantaneous current of the high-voltage cabinet, when the current exceeds a preset safety threshold, a signal is sent to the timer 3, the timer starts timing, and if the current returns to the safety threshold before the set time is reached, the circuit breaker 2 is not powered off; and when the current exceeds the safety threshold value all the time when the set time is reached, the circuit breaker 2 is powered off, and all power supplies of the high-voltage cabinet are cut off. When the high-voltage board operates, the air cooler is communicated with the rectangular pipe 7 through the communicating pipe, then the cold air is blown out from the upper surface and the lower surface of the rectangular pipe 7, so that each electric element can be cooled by the air from top to bottom and from bottom to top, the cooling of the real element is balanced, and the cold air cannot absorb heat when moving due to air supply through the pipeline, and the heat dissipation efficiency of the electric element far away from the air cooler is ensured.
The rectangular tubes 7 are arranged transversely. The air cooler 6 is communicated with all the rectangular tubes 7 through communicating tubes. The bottom of the cabinet body 5 is provided with supporting legs 9. The legs 9 are L-shaped.
The above-mentioned is only a concrete direction embodiment of the utility model, nevertheless the utility model discloses a design concept is not limited to this, and all utilize this design right the utility model discloses carry out immaterial change, all should belong to the action of infringing the scope of protection of the utility model.
