Description
Technical field
The present invention relates 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 requirement is " natural
Ventilation ", ring main unit is interior without means of ventilation, causes close to ring main unit ventilation opening, difference variation is maximum, and condensation is the most serious.It is adjacent
Ventilation opening is spaced away from, 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, with reference to 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, improves the design of existing instrument box.
Invention content
The invention will solve the problems, such as to be to provide a kind of anti-condensation instrument box, in existing ring main unit agent structure not
In the case of change, the condensation problem in instrument box is solved；The safety of product is improved simultaneously.
To solve the above-mentioned problems, the technical scheme is that：A kind of anti-condensation instrument box, including after panel box,
Top blind flange, chamber door, support ear, lower box are equipped with osculum, and condensation water is collected and guided equipped with rhone by cabinet wall
It is discharged to osculum.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 logical
Transom window.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.It is logical
There is arc-shaped rain shade outside transom window, Open Side Down.Rain shade can ensure that water spray does not enter box house.Top blind flange surrounding
There is frame to be fixed with babinet, in addition to louver(-vre), remaining position is required to seal.
There is top inclined plate in top blind flange, top inclined plate is embedded with resistance heating wire, and 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, reduces the generation of water droplet.
The steam that condensation generates is pooled at the osculum of chamber door downwards along top inclined plate, discharges babinet.
Condensation sensor is equipped in babinet, it is automatic to start Resistant heating system when condensation occurs.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, louver(-vre) can realize instrument box inner air flow, 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, compared with the prior art, the invention has the advantages that：The generation of condensation is prevented,
It 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 schematic diagram of the present invention；
Fig. 2 is top blind flange sectional view of the present invention.
Drawing reference numeral explanation：1st, 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 embodiment
The present invention 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, case
Body lower part is equipped with osculum, and cabinet wall is equipped with rhone and condensation water is collected and directed to osculum discharge.Top blind flange 2 is in
Ramped shaped, 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 is in 5-
Between 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 circular arc outside louver(-vre)
Shape rain shade, Open Side Down.Rain shade can ensure that water spray does not enter box house.Top blind flange surrounding have cover board frame 7 with
Babinet top is fixed, and in addition to louver(-vre), remaining position is required to seal.Air in instrument box passes through logical in top blind flange 2
Transom window 5 and external air currents.Guide rail, relay, terminal block, condensation controller are fixed in identical back plate 1 in instrument box
Deng on guide rail.Instrument box is fixed on ring main unit top by support ear 4.
There is top inclined plate 6 in top blind flange 2, top inclined plate 6 is embedded with resistance heating wire 6.1, and top inclined plate lower part has anti-
Moisture film 6.2.Resistance heating wire 6.1 is evenly distributed on top 6 middle and upper part of inclined plate.Resistance wire is insulated enclosure laminated structure.Top
Inclined plate 6 can embed 3-8 resistance heating wire 6.1.After 6.2 surface cleaning of waterproof membrane, one layer of waterproof oil film is sprayed, reduces water droplet
Generation.The steam that condensation generates is pooled at the osculum of chamber door downwards along top inclined plate, discharges babinet.
Condensation sensor is equipped in babinet, it is automatic to start Resistant heating system when condensation occurs.By reducing in babinet
The outer temperature difference reduces the generation of condensation.
In order to meet the requirement of IP55, water spray is avoided to enter babinet, top blind flange 2 can be designed as sinkage type structure.I.e.
The vertex of top blind flange is not higher than the frame on babinet top.After the design, top of the box does not have protruding portion.Due to there is ventilation
The protection of the rain shade and frame of window sprays water, is unable to spirt box house from top of the box and below, can be in guard box body
The component in portion.
Compared with the prior art, the invention has the advantages that：Under the premise of IP55 protection level requirements are ensured, improve
The mobility of box house air, effectively prevent the generation of condensation, improves the safety of ring main unit product operation.
