Description
[technical field]
The utility model relates generally to electrical equipment more particularly to a kind of terminal box for dehumidifying, dehumidifying.
[background technique]
Terminal box of transformer substation is the intermediate link that the equipment such as outdoor electrical equipment and indoor observing and controlling, protection, communication are connect, one
As be mounted on by equipment nearby.When there was dampness in the air, the moist condensation accumulated water especially within rainy season, outdoor switch terminal box, easily
Cause insulation against ground resistance in direct-current secondary circuit to decline, serious person's insulation resistance drops to zero, thus formed DC positive power or
Negative supply ground connection.If causing direct current two points ground fault, DC insurance is caused to fuse, relay fail or malfunction, or even damage are set
It is standby, seriously threaten the safe operation of power grid.Terminal box dampness makes terminal block screw and connection sheet get rusty, and makes secondary terminals contact not
It is good, it so that current transformer terminal fever is even opened a way, cause relay fail or malfunction, cause accident.Mutual inductor voltage
It is bad it will cause observing and controlling, protective device operation exception, mistaking signal with switch, temperature signal termination contact, cause to run people
Error analysis is made in member's erroneous judgement.
The various electrical equipments of current electric system (switch, disconnecting switch, voltage transformer etc.) terminal box is observed, is checked each
Material, production, mounting process and the damp circuit of drive of class terminal box etc., find moisture weight in terminal box, cause terminal board
Terminal, screw easy-to-rust, easy-to-rust in cabinet, constitute a serious threat to the safe and reliable operation of electrical equipment.Such as: some terminals
The screw iron of case, easy-to-rust, part terminal box door lock size mismatches, not closely, Yi Songdong；The fire prevention of part terminal box
Imprecision is blocked, is caused into water；Part terminal box drives that damp circuit does not connect power supply or circuit is obstructed, causes to drive damp effect bad；
Part terminal box carries out driving tide operation very inconvenient because of the defect that designed originally；It is not in place that there are also management aspects, and thunderstorm does not have later
Have to unpack to be aerated in time and drives tide etc..
The case where for humidity condensation accumulated water existing for current terminal box of transformer substation inside, in order to set terminal box of transformer substation
It is standby to achieve the purpose that automatic sustainable dehumidifying, the sustainable automatic dehumidification system of a set of terminal box of transformer substation is developed, to prevent not-go-end
Sub- case makes moist and accident occurs and has great importance.
Foreign & Domestic Substations mostly use greatly traditional heating moisture separating device at present, often because being formed after moisture separating device heating
Aqueous vapor can not be discharged and be condensed at the top of terminal box for a long time, formed dewdrop suspension, eventually drop onto the equipment such as terminal block again
On, cause equipment short circuit or ground connection, it is undesirable to drive damp effect.In addition, common heating moisture separating device is also easy to damage, or even meeting
Occur leading to problems such as heating plate overheat burn out running equipment due to heating for a long time.And the damp heating device of general drive do not have it is logical
Letter and networking function, if the working condition of temperature and humidity controller in terminal box need to be understood, it is necessary to be maked an inspection tour one by one, heavy workload
And it is inefficient, it can not also accomplish to understand its working condition in real time.
Terminal box conventional dehumidification measure:
Install sealing strip additional
Plastic sealing strip is installed additional in case, cabinet door, prevents rainwater from entering box house, there is certain effect.According to many years
Operating experience, sealing strip are easily corroded, are peeled off, and substantially every 2-3 is just needed replacing once, and biggish in outer moisture
In the case of, the humidity of box house can not be effectively reduced, the case where equipment mildew, corrosion is more serious in cabinet, it cannot be guaranteed that setting
Standby safe operation.
Install heater additional
Generally used in the power system at present is the mating heater of moisture probe, starts heating when humidity is excessively high
Device heats humid air, and the humid air after making heating rises.Damp-heat air can generate energy after encountering top of the box cooling after rising
Condensation reduces dielectric level instead, is unfavorable for the safe operation of equipment, and moisture still remains in box house, cannot be effective
Reduce bin equipment interior humidity.In south, summer temperature is high, and the humidity heat that greatly the interior operation original part of upper bin generates is various
Cable skin aging is serious, easily causes equipment fault.
