Abstract

The utility model relates to the technical field of electric system equipment, and specifically relates to an anti-condensation medium voltage switch cabinet. The switch cabinet comprises an enclosing metal cabinet body, and a handcart chamber, a bus chamber and a cable chamber are separately arranged in the cabinet body. The handcart chamber, the bus chamber and the cable chamber are respectively provided with a heating device and a humiture monitoring sensor. A humiture controller is disposed in the cabinet body. The heating devices and the humiture monitoring sensors are connected to the humiture controller through control signals. A control method by heating and dehumidifying is employed by the switch cabinet, and the humiture controller is employed as well. The humiture inside and outside the switch cabinet and the humiture in each separated chamber are monitored by the humiture controller, so that the humiture inside the switch cabinet is controlled, condensation phenomena are prevented effectively, and the safety and reliability of electric equipment operation is ensured.

Description

A kind of Medium Voltage Switchgear that prevents condensation
Technical field
The present invention relates to the power system device technical field, relate in particular to a kind of Medium Voltage Switchgear that prevents condensation.
Background technology
The stable operation of electric power system not only affects the sustainable development of national economy, and closely bound up with the people's daily life.Along with the development of science and technology, every profession and trade production and resident living have proposed more and more higher requirement to quality and the management of electric power supply, and State Grid Corporation of China has also proposed the concept of intelligent grid.As the elementary cell of electrical network, the 10KV medium voltage switchgear equipment must change traditional design and control model just can be complied with the trend of social development, could be for realizing that intelligent grid lays the foundation.
Traditional Medium Voltage Switchgear adopts the metal cabinet of sealing, and isolation is provided with some bins in the cabinet, because the inside and outside humiture environmental difference of cabinet easily forms water droplet at the metal surface of cabinet condensation, causes equipment fault.Existing switch cubicle arranges heater for solving condensation problem in cabinet, although drying by the heater heating, cabinet can play certain anti-condensation effect, but owing to being provided with the bin of some mutual isolation in the cabinet, and the heat that the electric equipment of each bin distributes is different, cause the humiture difference that exists between each bin, therefore its effect that prevents condensation is bad, the condensation phenomenon that the humiture environmental difference causes inside and outside the high humidity environment lower cabinet body be can not effectively solve, thereby power equipment reliability of operation and fail safe affected.
Summary of the invention
The object of the invention is to provides a kind of Medium Voltage Switchgear that prevents condensation for the existing problem of prior art, originally the Medium Voltage Switchgear that prevents condensation does not singly adopt the heating and dehumidification control mode, be provided with simultaneously temperature and humidity controller, monitor the humiture of respectively isolating bin inside and outside the cabinet in the humiture and cabinet by temperature and humidity controller, and then controlling humiture in the cabinet, thereby can effectively prevent the condensation phenomenon, ensure that power equipment is safe and reliable to operation.
For achieving the above object, the present invention is achieved through the following technical solutions.
A kind of Medium Voltage Switchgear that prevents condensation, the metal cabinet that comprises sealing, isolation is provided with handcart chamber, bus-bar room and cable vault in the cabinet, handcart chamber, bus-bar room and cable vault are provided with heater and temperature-humidity monitoring transducer respectively, be provided with temperature and humidity controller on the described cabinet, described heater be connected the temperature-humidity monitoring transducer and be connected with described temperature and humidity controller control signal respectively.
Wherein, on the sidewall that the heater of described handcart chamber and Temperature Humidity Sensor are installed on described cabinet.
Wherein, the heater of described bus-bar room and Temperature Humidity Sensor are installed on the rear plate of described cabinet.
Wherein, the heater of described cable vault and Temperature Humidity Sensor are installed on the rear plate of described cabinet.
Wherein, offer observation window in the position of corresponding handcart chamber, bus-bar room and cable vault respectively on the described cabinet.
Beneficial effect of the present invention is: the Medium Voltage Switchgear that originally prevents condensation does not singly adopt the heating and dehumidification control mode, be provided with simultaneously temperature and humidity controller, monitor the humiture of respectively isolating bin inside and outside the cabinet in the humiture and cabinet by temperature and humidity controller, and then controlling humiture in the cabinet, thereby can effectively prevent the condensation phenomenon, ensure that power equipment is safe and reliable to operation.
Description of drawings
Fig. 1 is Facad structure schematic diagram of the present invention;
Fig. 2 is the internal structure schematic diagram of side of the present invention.
In Fig. 1 to Fig. 2, include:
10, cabinet; 11, temperature and humidity controller; 21, handcart chamber; 22, bus-bar room;
