Abstract
The utility model relates to a safe cooling high-voltage ring main unit with a compact structure. The ring main unit comprises a cabinet which is divided into an instrument chamber and a switch chamber from top to bottom successively by a separator plate. A disconnecting switch, a vacuum load switch and a grounding switch are provided inside the switch chamber and are integrated into one piece. A cooling and dehumidifying device is provided inside the cabinet, and comprises a cooling vent arranged in a side wall of the cabinet, a blower arranged in the cooling vent, and a sensor and a controller which are arranged inside the cabinet. The controller is connected to the sensor and the blower separately. The beneficial effects are that the ring main unit is compact in structure and reasonable in design; and the cooling and dehumidifying device can effectively maintain the temperature and humidity inside the cabinet, so that the service life of the cabinet is ensured.
Description
Technical field
The utility model relates to the High voltage power supply equipment technical field, especially relates to a kind of safety heat radiation high-voltage ring main unit of compact conformation.
Background technology
High-voltage ring main unit is widely used in the power distribution stations and box-type substation of electric power for the center such as uptown, skyscraper, factory, is the cable branch box of belt switch in the ring network power supply system, and its turnover line end is by cable connection.Isolating switch, vacuum load switch body and earthed switch in the high-voltage ring main unit cabinet all is comprised of scattered parts at present, and operating mechanism separately is separate, like this so that cabinet overall dimension is excessive, and operating mechanism inconvenient operation, take a large amount of spaces, enlarged the floor space of transformer station.In addition, can discharge certain heat during owing to high-voltage ring main unit work, have a strong impact on useful life and the electric property of ring main unit, high temperature causes ageing equipment easily, reduces useful life; High humidity affects the electric property of equipment, and discharge and short circuit occur easily.
Therefore, a kind of compact conformation, easy to operate, long service life, the dehumidifying of can in time dispelling the heat simultaneously the appearance of high-voltage ring main unit necessary.
The utility model content
The utility model is to provide a kind of compact conformation for solving the problems of the technologies described above, and is easy to operate, long service life, the dehumidifying of can in time dispelling the heat simultaneously high-voltage ring main unit.
The technical problem that the utility model solves realizes by the following technical solutions:
The safety heat radiation high-voltage ring main unit of compact conformation, comprise cabinet, described cabinet is divided into control room, switch gear room from top to bottom successively by dividing plate, in described switch gear room, be provided with isolating switch, vacuum load switch and earthed switch, described isolating switch, vacuum load switch and earthed switch are integrated, and have effectively reduced the space;
In described cabinet, be provided with the heat radiation dehydrating unit, described heat radiation dehydrating unit comprises the louvre that is arranged on the described cabinet sidewall, be arranged at the blower fan in the described louvre and be arranged at transducer and controller in the described cabinet, and described controller is connected with blower fan with transducer respectively.
As preferred technical scheme, described transducer comprises temperature sensor and humidity sensor.
The beneficial effect that the utlity model has is: compact conformation, relate to rationally, and can effectively keep temperature and humidity in the cabinet by the heat radiation dehydrating unit, guaranteed the useful life of cabinet.
