The ring main unit is provided with a moisture-proof apparatus by which moisture in the ring main unit can be changed into liquid water and directly discharged out of the ring main unit. The moisture-proof apparatus comprises a power supply, a dehumidifier and a controller, wherein the power supply and the dehumidifier are connected with the controller; the power supply comprises a solar cell panel and a storage battery; the solar cell panel is connected with the controller, and the storage battery is connected with the controller; and the dehumidifier is a condensing dehydration-type dehumidifier. According to the utility model, a condensing dehydration-type dehumidifier is used to solve the problem of moisture condensation in the ring main unit, and the moisture in the ring main unit can be changed into liquid water and directly discharged out of the ring main unit, so that the problem of moisture in the ring main unit is solved and the failure rate caused by the condensation in the equipment is reduced; besides, the solar energy and the storage battery are both used for power supply, so that the dehumidifier is ensured to work in normal whether day or night.
Description
Technical field
The utility model relates to a kind of ring main unit, particularly a kind of moistureproof ring main unit.
Background technology
Ring main unit claims again high-tension switch cabinet, and its effect is to improve power supply reliability, to guarantee not running overload of high voltage bus in service.If but the position that ring main unit is laid is in the place that annual cloud and mist is many, sunshine is few, landform is inaccessible, air humidity is large, so that the ring main unit operational environment is more abominable, being installed in outdoor ring main unit stands to expose to the sun and rain for a long time, moisture in the cable trough also can be invaded in the case simultaneously, cause in the case the excessive and dewfall of humidity, cause the dielectric strength of electric equipment switch, disconnecting link and connecting terminal block in the ring main unit to reduce and the generation flashover, cause that switch mistake is closed, false tripping and cause equipment fault, have a strong impact on the safe operation of electrical network.
Baker is often adopted in existing ring main unit dehumidifying, its principle is by ring main unit inside is heated, in-cabinet temperature constantly raises, because the air of higher temperature can comprise more moisture, and can impel the condensation on equipment to evaporate, thereby prevent directly condensation on the electric equipment terminal board etc. in case of aqueous vapor, the accidents such as prevention flashover, short circuit.But the moisture that comprises in the higher temperature air rests in the air always, when waiting variation of ambient temperature round the clock, the moisture that comprises in the air is separated out, and larger air humidity will cause rapidly condensation, thermal source can impel the aging of electric equipment simultaneously, the harm equipment safety operation.
If the employing temperature-controlled fan is removed the moisture in the ring main unit, although temperature-controlled fan can carry out to in-cabinet temperature the adjusting of appropriateness, to reach the air humidity in the control cubicle, be easy to installation and cost lower.But ring main unit temperature-controlled fan poor effect in wet environment, the generation that can not effectively solve condensation.
Therefore need a kind of device that can effectively eliminate fast the moisture condensation in the ring main unit.
The utility model content
In view of this, technical problem to be solved in the utility model provides a kind of device that can effectively eliminate fast the moisture condensation in the ring main unit.
The utility model is achieved through the following technical solutions:
The ring main unit that is provided with damp-proof device that the utility model provides, be provided with in the described ring main unit for the moisture in the ring main unit being changed into aqueous water and directly be discharged to the outer damp-proof device of ring main unit, described damp-proof device comprises power supply, dehumidifier and controller, and described power supply is connected with controller with dehumidifier and is connected.
Further, described power supply comprises solar panel and storage battery, and described solar panel is connected with controller, and described storage battery is connected with controller.
Further, described dehumidifier is the condensation type dehumidifier that anhydrates.
Further, described ring main unit body fuselage is alloy material shell.
The beneficial effects of the utility model are: the utility model adopts the condensation type dehumidifier that anhydrates to eliminate ring main unit inner moisture condensation problem, it can directly change the moisture in the electric cabinet into aqueous water and directly be discharged to outside the cabinet, thoroughly solve the moisture puzzlement in the electric cabinet, reduced the failure rate that the device interior condensation causes, utilize simultaneously solar powered and the storage battery accumulate, no matter like this daytime or night, can guarantee that all dehumidifier normally moves.The ring main unit that is provided with damp-proof device has prevented the generation of ring main unit internal condensation phenomenon effectively, the accident probability that is caused by the equipment condensation has been reduced to 6% by original 64%, ensure safe operation and the personal security of electrical network, guaranteed power supply quality, improved power supply reliability.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being apparent to those skilled in the art to investigating hereinafter, perhaps can from practice of the present utility model, be instructed.Target of the present utility model and other advantages can realize and obtain by following specification and claims.
