Abstract
The utility model relates to an outside common-box-type high voltage busbar groove with a temperature and humidity controller and belongs to electrical equipment. The outside common-box-type high voltage busbar groove with the temperature and humidity controller comprises a busbar groove shell body, insulators, a busbar row, a temperature and humidity sensor, an electric heater and the temperature and humidity controller, and the temperature and humidity controller is disposed in an instrument chamber of a high voltage cabinet. The busbar row is disposed in the busbar groove shell body, the insulators are disposed on the busbar row, the temperature and humidity sensor and the electric heater are disposed below the busbar row and at the bottom inside the busbar groove shell body, the temperature and humidity controller which is used for controlling the temperature and humidity sensor and the electric heater is disposed in the instrument chamber of the high voltage cabinet, and the temperature and humidity controller is respectively in electric connection with the temperature and humidity sensor and the electric heater. When the outside common-box-type high voltage busbar groove with the temperature and humidity controller is used, generation conditions of condensation and frost returning phenomena are effectively stopped, and phase to phase insulation flashover accidents and relative insulation flashover accidents of the high voltage busbar row are avoided. Therefore, the outside common-box-type high voltage busbar groove with the temperature and humidity controller provides good reliability and continuity for customers.
Description
Technical field
The utility model relates to electric information, and particularly a kind of outdoor common box type high voltage bus groove with Temperature and Humidity Control refers to be applicable to the outdoor common box type high voltage bus groove of electric substation with the band Temperature and Humidity Control especially.
Background technology
During the design of outdoor high-voltage bus duct was at home and abroad produced, shown in accompanying drawing 1, existing bus duct all was made up of the busbar 3 of protecting sheathing bus cell body 1, the insulator 2 that plays insulating effect and a current-carrying electric action, does not install electric heater basically additional.And in service at actual outdoor high-voltage bus duct; Because the effect of cell body internal-external temperature difference; The existence of hydrone is arranged in the air, condensation often takes place return white phenomenon, cause high pressure busbar phase insulation flashover to reach insulation flashover relatively; Cause utmost point negative consequence to equipment operation, and then influence the reliability and the continuity of user's power supply.
The utility model content
The purpose of the utility model is to provide a kind of outdoor common box type high voltage bus groove with Temperature and Humidity Control; Solve the in service of outdoor high-voltage bus duct,, condensation often takes place return white phenomenon because the existence of hydrone is arranged in the effect of cell body internal-external temperature difference and the air; Cause high pressure busbar phase insulation flashover to reach insulation flashover relatively; Cause the problem of utmost point negative consequence to equipment operation, and then improve the reliability of power supply, satisfy user's instructions for use.
The utility model specifically includes: bus groove case, insulator, busbar, Temperature Humidity Sensor, heater and be positioned at high-voltage board control room temperature and humidity controller.Its busbar is installed in the bus groove case, and at least two insulators are installed on busbar; Bottom in bus groove case and Temperature Humidity Sensor and electric heater are installed in the downside of busbar; The temperature and humidity controller that is used to control its Temperature Humidity Sensor and electric heater is installed in the high-voltage board control room, and its Temperature Humidity Sensor and electric heater and temperature and humidity controller electrically connect, and then realize the control of humiture in the control high voltage bus groove.
Concrete control method is: when in the bus groove case because internal-external temperature difference when the condensation phenomenon being arranged and returning white phenomenon and take place; Temperature Humidity Sensor sends signal and gives temperature and humidity controller; The temperature and humidity controller judgement is compared when deviation occurring with set temperature value; Send control signal and give the electric heater that is installed in bus groove case, electric heater begins heating, and the bus groove case internal temperature rises gradually; When the bus groove case internal temperature reaches the ceiling temperature value of setting; Temperature Humidity Sensor sends temperature information to temperature and humidity controller; Temperature and humidity controller control electric heater stops heating; Prevent condensation and the generation condition of returning white phenomenon thus, prevented to cause high pressure busbar phase insulation flashover and the generation of insulation flashover accident relatively.
The advantage of the utility model: increase the power supply reliability of outdoor high-voltage bus duct, the continuity for the user provides electricity consumption satisfies user's instructions for use.
Description of drawings
Fig. 1 is existing outdoor high-voltage bus duct principle schematic.
Fig. 2 is the utility model outdoor high-voltage bus duct principle schematic.
Embodiment
Shown in accompanying drawing 2, be the utility model outdoor high-voltage bus duct principle schematic.Can find out that by accompanying drawing the utility model includes: bus groove case 1, insulator 2, busbar 3, Temperature Humidity Sensor 4, temperature and humidity controller 5, electric heater 6.In its bus groove case 1 busbar 3 is installed, on busbar 3, is provided with two insulators 2, the bottom in bus groove case 1 and one Temperature Humidity Sensor 4 and an electric heater 6 are installed in busbar 3 downsides; One Temperature Humidity Sensor 4 and electric heater 6 that are used to control in its bus groove case 1 is installed in the high-voltage board control room, and then the temperature and humidity controller 5 of humiture in the control high voltage bus groove.In bus groove case 1, the condensation phenomenon occurs and return white phenomenon generation owing to internal-external temperature difference; Temperature Humidity Sensor 4 sends information and gives temperature and humidity controller 5; When temperature and humidity controller 5 judgements have been compared deviation with set temperature value; Temperature and humidity controller 5 sends control information and gives the electric heater 6 that is installed in the bus groove case 1, make electric heater 6 heating, so that bus groove case 1 internal temperature rises gradually; When bus groove case 1 internal temperature reaches the ceiling temperature value of setting; Temperature Humidity Sensor 4 sends temperature information at this moment to temperature and humidity controller 5; Temperature and humidity controller 5 is controlled electric heaters 6 and is stopped heating, has prevented condensation and the generation condition of returning white phenomenon thus, prevents to cause high pressure busbar phase insulation flashover and the generation of insulation flashover accident relatively; Operation causes disadvantageous consequence to power supply unit, and then with the user good reliability and continuity is provided.
