Abstract
The utility model provides a special air door is shielded to direct current charger. Its upper portion middle part is formed with a glass observation window, and left and right sides edge is formed with one respectively and is listed as rectangle ventilation hole, and well lower part middle part is formed with a plurality of round holes to the marginal mid -mounting in one side has a hand (hold). The utility model provides a special air door is shielded to direct current charger is last to have a large amount of ventilation holes, consequently can improve the inside natural cooling efficiency of direct current charger screen casing greatly, can reduce because the overheated and module fault rate of charging that lead to the fact from this to guarantee the direct current system's of transformer substation safe and reliable operation.
Description
Technical field
This utility model belongs to electrical equipment technical field, particularly relates to a kind of DC charging motor screen special logical
Air door.
Background technology
In power system, transformer station direct current system provides unidirectional current for first and second equipment for transformer station
Source, is the heart of transformer station, mainly by DC charging motor screen, outgoing screen group, point electric screen group, accumulator
Several parts compositions such as group.Wherein, the charging mould of about 5 it is provided with in the housing of each DC charging motor screen
Block, top is provided with LCDs, and during running, these charging modules can produce substantial amounts of heat,
Although the top of DC charging motor screen is provided with heat transmission blower fan, but because its front/rear door is all hermetic glass door,
Not having fresh air inlet, be therefore unfavorable for the heat radiation of charging module, result may cause charging module too high because of temperature
And out of service, thus cause DC system fault, bring to the safe operation of transformer station first and second equipment
Accident potential greatly.
Summary of the invention
In order to solve the problems referred to above, the purpose of this utility model is to provide a kind of DC charging motor screen special logical
Air door.
In order to achieve the above object, in the top of the special air door of DC charging motor screen that this utility model provides
Between position be formed with a glass window, edge, the left and right sides is respectively formed with string rectangular ventilation holes, in
Lower middle portion is formed with multiple circular hole, and side marginal center is provided with a hands handle.
The size of described rectangular ventilation holes is 5mm*30mm, a diameter of 5mm of circular hole.
The position of described glass window and the position of the LCDs of setting in DC charging motor screen housing
Corresponding, and size is more than the size of LCDs.
Described hands is for the cabinet door special lockset with lock core.
With substantial amounts of air vent on the special air door of DC charging motor screen that this utility model provides, therefore can
Enough be greatly improved the natural heat dissipation efficiency of DC charging motor screen enclosure interior, thus can reduce due to overheated and
The charging module fault rate caused, thus ensure the safe and reliable operation of transformer station direct current system.
Accompanying drawing explanation
The DC charging motor screen special air door structural representation that Fig. 1 provides for this utility model.
Detailed description of the invention
The special air door of DC charging motor screen with specific embodiment, this utility model provided below in conjunction with the accompanying drawings
It is described in detail.
As it is shown in figure 1, middle part, the top shape of the special air door of DC charging motor screen of this utility model offer
Cheng Youyi glass window 1, edge, the left and right sides is respectively formed with string rectangular ventilation holes 2, in middle and lower part
Between position be formed with multiple circular hole 3, and side marginal center is provided with a hands 4.
The size of described rectangular ventilation holes 2 is 5mm*30mm, a diameter of 5mm of circular hole 3.
The position of described glass window 1 and the position of the LCDs of setting in DC charging motor screen housing
Put corresponding, and size is more than the size of LCDs.
Described hands is the cabinet door special lockset with lock core 4.
Only hermetically sealed glass door before and after on original DC charging motor screen housing need to be disassembled during use,
Replace with the special air door of DC charging motor screen that this utility model provides.In running, can profit
With the heat transmission blower fan at DC charging motor screen top by outer gas stream from the DC charging motor screen being positioned at front or rear portion
Air vent on special air door sucks, and is taken away by the heat that its surface distributes, then after charging module
Discharged by the air vent on another special air door of DC charging motor screen, thus reduce charging mould
The effect of deblocking temperature.
