Description
Technical field
The utility model is related to electrical equipment, especially a kind of instrument box of middle pressure ring main unit.
Background technology
With the sustainable development of China's economic, electrical equipment has obtained significant progress.Middle pressure ring main unit has been power distribution network
The switchgear of mainstream.Ring main unit bottom is heater, is topmost instrument box, is where relay, and centre is operating mechanism,
Bottom is cable vault and heater.Instrument box meets the IP55 degree of protection of typical design requirements.Ring main unit requires to be " natural
Ventilation ", ring main unit is interior without means of ventilation, causes close to ring main unit ventilation opening, and difference variation is maximum, and condensation is the most serious.It is adjacent
It is spaced away from ventilation opening, although condensation is in the presence of being not so serious.It is instrument box at the top of ring main unit, is pressed in main installation
Looped network cabinet controller and detection unit.There are various low-voltage control lines, relay, connecting terminal block in instrument box.Instrument box top
Portion is sealing structure, degree of protection IP55.The winter temperature difference is larger, under condensation serious situation, can reduce the insulation between conducting wire
Level results even in relay tip heavy corrosion.Existing design code requirement is equipped with anti-condensation heater by standard,
But heater is mounted on the bottom of ring main unit, in conjunction with ring main unit air outlet low temperature environment, air is made to be easier at top instead
Cause condensation.Therefore the failure brought for condensation is needed, the design of existing instrument box is improved.
Invention content
The utility model creation will solve the problems, such as to be to provide a kind of anti-condensation instrument box, in existing ring main unit main body knot
In the case that structure is constant, the condensation problem in instrument box is solved；The safety of product is improved simultaneously.
To solve the above-mentioned problems, the technical solution of the utility model is：A kind of anti-condensation instrument box, including after babinet
Plate, top blind flange, chamber door, support ear, lower box are equipped with osculum, and condensation water is collected and drawn equipped with rhone by cabinet wall
Lead osculum discharge.Top blind flange is in ramped shaped, and the gradient is between 5-15 degree.Top blind flange side is hermetically sealed, and rear portion is provided with
Louver(-vre).For the gradient between 5-10 degree, row's louver(-vre) is opened at rear portion；For the gradient between 11-15 degree, two row's louver(-vre)s are opened at rear portion.
There is arc-shaped rain shade outside louver(-vre), Open Side Down.Rain shade can ensure that water spray does not enter box house.Top blind flange four
Week has frame to be fixed with babinet, and in addition to louver(-vre), remaining position is required to seal.
There are top inclined plate, top inclined plate to be embedded with resistance heating wire in top blind flange, waterproof membrane is arranged at top inclined plate lower part.Electricity
Resistance heater strip is evenly distributed on top inclined plate middle and upper part.Resistance wire is insulated enclosure laminated structure.Top inclined plate can embed 3-8
Resistance heating wire, take the shape of the letter U wavy arrangement.After waterproof membrane surface cleaning, one layer of waterproof oil film is sprayed, the generation of water droplet is reduced.
The steam that condensation generates is pooled at the osculum of chamber door downwards along top inclined plate, and babinet is discharged.
Condensation sensor is equipped in babinet, when condensation occurs, automatic start-up resistor silk heating system.By reducing in babinet
The outer temperature difference reduces the generation of condensation.
In order to avoid water spray enters babinet, top blind flange can be designed as sinkage type structure.That is top blind flange vertex is not high
Frame in babinet top.After the design, top of the box does not have protruding portion.Due to having the rain shade of louver(-vre) and frame
Protection sprays water, is unable to spirt box house, can protect the component of box house from top of the box and below.
In above-mentioned technical proposal, instrument box inner air flow may be implemented in louver(-vre), and top inclined plate can make steam along tiltedly
Face is pooled to osculum, and resistance heating wire can improve the temperature in babinet and prevent terminal and connector by cargo sweat, waterproof membrane
Can to avoid water droplet aggregation and drop onto on the component in babinet.
As a result of above-mentioned design, the advantageous effect of the utility model compared with prior art is：Prevent condensation
It generates, avoids component terminal and junction makes moist the damage brought.
Description of the drawings
It is further illustrated with reference to legend：
Fig. 1 is utility model diagram；
Fig. 2 is the utility model top blind flange sectional view.
Drawing reference numeral explanation：1, after panel box, 2, top blind flange, 3, chamber door, 4, support ear, 5, louver(-vre), 6, top it is oblique
Plate, 6.1, resistance heating wire, 6.2, waterproof membrane, 7, cover board frame.
Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing embodiment.
Embodiment 1
As shown in Figure 1 and Figure 2, a kind of anti-condensation instrument box, including after panel box 1, top blind flange 2, chamber door 3, support ear
4, lower box is equipped with osculum, and cabinet wall is equipped with rhone and condensation water is collected and directed to osculum discharge.Top cover
Plate 2 is in ramped shaped, and the gradient is between 5-15 degree.Top blind flange side is hermetically sealed, and rear portion is provided with louver(-vre) 5.2 gradient of top blind flange
