Description
Technical field
This utility model belongs to power domain, is specifically related to a kind of outdoor electrical equipment terminal box anti-condensation device.
Background technology
Season in spring and autumn and southern rainy season whenever the north, generally there is dew condensation phenomenon in the outdoor electric equipment box of each transformer station of power supply administration, as a example by locating northerly Inner Mongolia Ultrahigh Voltage Power Supply Administration, Resonant Sand Gorge therein, Bu Dou transformer station are the most obvious, and serious dew condensation phenomenon occurs in box house.
Through field observation and analysis, casing and the cable interface that extraneous electrical link is the lower section by casing, cable has carried out encapsulation process by fireproof blocking layer to casing when entering casing, owing to physical differences is very big between casing, cable, plugging material, arise that poorly sealed situation through after a while.It addition, for dust-proof consideration, chamber door frame generally also has sealing ring, it is an environment closed inside electrical box.Equipment box is often connected with the cable duct of underground (being isolated by the fireproof blocking layer of cable), buried cable ditch ambient humidity is bigger than environment on the ground, out of doors in running environment, the most northerly season in spring and autumn, in the case of day and night temperature is relatively big, the dampness entering casing easily forms condensation or hangs frost phenomenon, causes electric insulation to decline, increases the security risk of electrical equipment greatly.
Additionally, coordinate the service work on electrical equipment, need when (maintenance power box) box house draws (introducing) test cable or power cable, current mode is to open chamber door directly to carry out the extraction (introducing) of cable, if running into strong wind, airborne dust, rain, the vile weathers such as snow, electrical equipment is exposed in external environment after opening by chamber door, pole is unfavorable for that equipment is dust-proof and insulate, internally charged equipment lacks effective quarantine measures, too increase the security risk of staff, it is easily caused the apparatus insulated reduction of electric component box or corrosion, even mildew, secondary device is caused to damage, DC earthing, mechanism's clamping stagnation, the problems such as protection device mistrip, to power grid security, operation brings serious threat.
