Background technology
Terminal box (including including the central console of GIS stations) is one of transformer station's visual plant, and it act as contact first and second and sets
It is standby, for primary equipment provides control power supply, electrical source of power, the safety and Health fortune of its safe and reliable operation direct relation transformer station
OK.For outdoor terminal box, maximum problem is easily internally formed solidifying in terminal box when being temperature reduction and larger humidity
Dew, the globule of formation can be attached on its internal metal and parts of plastics, will cause following harm：
1st, the dew formed on secondary wiring terminals row in terminal box causes corruption to the metallic conduction position in terminal block
Erosion, corrodes heavier or easily causes alternating current-direct current short circuit grounding after being mixed into other impurity such as dust, and DC earthing is to substation secondary system
The stable operation of system causes greatly harm.Actual O＆M experience have shown that DC earthing mostly be by water loading on powered position
Cause, and more seriously dew even causes the short circuit in terminal block between two secondary lines, if precisely switch trip
Loop then can immediately cause switch misoperation, cause power outage.
2nd, condensation causes metal equipment corrosion in terminal box, corrosion, and serious curtailment equipment (contactor, relay etc.) is used
Life-span, cause metal contact wires contact resistance increase, occur monitoring backstage signal by mistake send out, energy storing of switch power supply, disconnecting link control and
Motor power disappears, influence primary equipment regular event, reduces the Efficiency of Switching Operation.
3rd, condensation causes to fix the screw corrosion of support in terminal box, and screw can be made to lose fixed branch after long-time use
Support is acted on so that box equipment comes off, and influences the normal operation of equipment.
Therefore, it is badly in need of a kind of good sealing effect of exploitation, can effectively prevents condensation, it is ensured that it is anti-condensation that terminal box normally runs
Terminal box structure.
The content of the invention
In view of this, the purpose of this utility model is to provide a kind of anti-condensation terminal box structure, and good sealing effect can
Effectively prevent condensation, it is ensured that terminal box normally runs.
Anti-condensation terminal box structure of the present utility model, including casing and chamber door, the casing front are provided with opening, institute
The edge for stating opening is provided with sealing strip I, and the closing lid face surrounding of the chamber door is provided with sealing strip II, the casing top
Air vent is provided with, one-way ventilating film is provided with the air vent, the inner surface of the casing bottom wall is coated with the stifled mud layer of fire prevention,
Sealant layer is coated with the stifled mud layer of fire prevention.
Further, the sealing strip I and sealing strip II are made of ethylene propylene diene monomer (EPDM) material.
Further, the one-way ventilating film is polytetrafluoroethylene (PTFE) waterproof ventilated membrane.
Further, the thickness of the stifled mud layer of the fire prevention is 10~20mm, and sealant layer is polymeric seal glue-line.
Further, it is provided with dehumidifier in the casing.
Further, the bottom half is provided with support base.
The beneficial effects of the utility model：Anti-condensation terminal box structure of the present utility model, is opened by being arranged on casing
The sealing strip I of the mouth and sealing strip II being arranged on chamber door closing lid face, after covering casing and chamber door, it is possible to increase sealing effect
Really；Simultaneously by setting one-way ventilating film on ventilating opening, moisture and steam in casing is set outwardly to discharge, and it is extraneous
Moisture will not enter casing in, it is ensured that effective isolation of moisture inside and outside casing；By setting fire prevention stifled mud layer and sealant layer,
Plugging strength can be effectively improved and dual-seal is formed, sealing property is further improved, so that the utility model sealing effect
It is really good, can effectively prevent condensation, it is ensured that terminal box normally runs.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings and examples：
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Fig. 1 is structural representation of the present utility model, as shown in the figure：The anti-condensation terminal box structure of the present embodiment, bag
Include casing 1 and chamber door 2, the front of the casing 1 is provided with open 3, open 3 edge is provided with sealing strip I4, described
The closing lid face surrounding of chamber door 2 is provided with sealing strip II5, by setting sealing strip I4 and sealing strip II5, covers casing and chamber door
After can form dual-seal, improve sealing effectiveness；The top of the casing 1 is provided with air vent 6, is provided with the air vent 6
One-way ventilating film 7, one-way ventilating film 7 is fixed on the inwall of casing 1, moisture and steam in casing is outwardly discharged,
And the moisture in the external world will not enter in casing, it is ensured that effective isolation of moisture inside and outside casing, sealing effectiveness is further improved, prevented
Condensation is produced；The inner surface of the bottom wall of the casing 1 is coated with the stifled mud layer 8 of fire prevention, to improve plugging effect and intensity, the fire prevention
Sealant layer 9 is coated with stifled mud layer 8, secondary seal can be formed to the bottom wall of casing 1, preferably casing 1 can carried out close
Envelope, prevents moisture from entering.
In the present embodiment, the sealing strip I4 and sealing strip II5 are made of ethylene propylene diene monomer (EPDM) material, with machinery
Performance is high, low temperature performance well, can reach -50 DEG C, the advantage of long service life, and these need to often be switched to be particularly suited for terminal box
The structure of chamber door.
