The heat dissipation structure of the dry type transformer comprises a fan and further comprises temperature sensors, a temperature controller, an alarm and a proximity switch. The temperature sensors are installed at the center positions between high-voltage coils and low-voltage coils respectively, and the temperature sensors which are connected in parallel are connected with the temperature controller respectively; the temperature controller is connected with the fan and the alarm, the proximity switch is arranged on a door frame of a transformer shell, the proximity switch is also connected with the alarm, and the proximity switch is connected with the temperature controller in parallel. The heat dissipation structure of the dry type transformer can achieve intelligent heat dissipation according to data collected by the temperature sensors and through control of the temperature controller, can further give an alarm in necessity, is reliable in operation, and saves energy.
Description
Technical field
The present invention relates to a kind of transformer part, specifically a kind of radiator structure of dry-type transformer.
Background technology
In modern society, transformer is one of visual plant in industrial and mining enterprises and civil buildings power supply-distribution system, in electric equipment and radio-circuit, transformer is commonly used for lifting voltage, matched impedance, safety isolation etc., according to methods for cooling, classify, transformer can be divided into dry-type transformer and the large class of oil-filled transformer two.
With respect to oil-filled transformer, dry-type transformer is not because there is no oil, namely there is no the serious problems such as fire, blast, pollution, therefore electrical code, rules etc. all require, dry-type transformer is not placed in independent room, according to < < China dry-type transformer research report prediction > > data, show, dry-type transformer on average accounts for 15%～20% in big or middle city, and in Beijing, the city such as Shanghai, Guangzhou, Shenzhen, account for 50% left and right.
Dry-type transformer mainly dispels the heat by air, the radiator structure of dry-type transformer is provided with fan on transformer shell at present, by the rotation of fan, accelerate flowing of air, strengthen radiating effect, but can rotate at transformer duration of work during the fan normal operation at present on transformer always, even transformer inside is without fan cooling during cold weather, fan also can keep rotating, if if there is fault, again can stall, cause transformer over-heat inside, like this not only bad for energy savings, and the reliability of work is very low.
In addition, overheated if transformer inside occurs, staff often will open transformer door and check fault and strengthen heat radiation, if but in the situation that transformer moves, open transformer door, there is very large potential safety hazard.
Summary of the invention
The object of the present invention is to provide a kind of radiator structure of dry-type transformer, this radiator structure can be realized intelligent heat radiation according to the temperature of transformer inside, and if open transformer door and can send warning under the state of transformer operation.
The present invention solves the technical scheme that its technical problem takes: the radiator structure of dry-type transformer, comprise the fan being arranged on transformer shell, and also comprise temperature sensor, thermostat, alarm and approach switch; Described temperature sensor has three, and three temperature sensors are arranged on respectively the center between three groups of high-tension coils and low-voltage coil, and three temperature sensors are relation in parallel and are connected with thermostat respectively; Thermostat is arranged in transformer shell, and thermostat connects fan and alarm, and alarm is arranged on the outer surface of transformer shell; On the doorframe of transformer shell, be provided with an approach switch, described approach switch is also connected with alarm, and approach switch is relation in parallel with thermostat.
The invention has the beneficial effects as follows:
The data that 1, can gather according to temperature sensor and the control of passing through thermostat realize intelligent heat radiation, can also realize warning if desired, and reliable operation, saves the energy.
2, doorframe is provided with approach switch, and approach switch connects alarm, need to open transformer door and check when fault or reinforcement are dispelled the heat, if transformer, in running status, can send warning, has improved fail safe.
Accompanying drawing explanation
Fig. 1 is structural principle schematic diagram of the present invention.
Embodiment
As shown in Figure 1, the radiator structure of dry-type transformer, comprises the fan being arranged on transformer shell, also comprises temperature sensor, thermostat, alarm and approach switch; Described temperature sensor has three, and three temperature sensors are arranged on respectively the center between three groups of high-tension coils and low-voltage coil, and three temperature sensors are relation in parallel and are connected with thermostat respectively; Thermostat is arranged in transformer shell, and thermostat connects fan and alarm, and alarm is arranged on the outer surface of transformer shell; On the doorframe of transformer shell, be provided with an approach switch, described approach switch is also connected with alarm, and approach switch is relation in parallel with thermostat.
Operation principle of the present invention is: two temperature shelves are set on thermostat, temperature sensor can detect the temperature between high-tension coil and low-voltage coil in real time, the temperature detecting when temperature sensor is lower, during without fan cooling, fan is failure to actuate, when temperature raises, arrive first temperature shelves of thermostat, while needing fan cooling, thermostat is controlled fan operation.If temperature continue to raise, transformer over-heat inside, has reached second temperature shelves of thermostat, and thermostat can be controlled alarm and send warning, and now people need to allow transformer quit work, and open transformer door and check that together heat distributes as early as possible constantly.No matter be when transformer is overheated or when other situations need to be opened transformer door, if do not allow transformer quit work when people open transformer door, when opening transformer door, can make approach switch action, alarm can be reported to the police, and reminds people's standard operation.The in the situation that of opening transformer door after it being quit work for transformer power-off, transformer and each parts are in cold state, so alarm can not reported to the police again.
The above, principles more of the present invention just explain through diagrams, this specification is not that in concrete structure and the scope of application described shown in the present invention will being confined to, therefore the corresponding modify being likely utilized every and equivalent, all belong to the scope of the claims that the present invention applies for.
Except technical characterictic described in specification, all the other technical characterictics are those skilled in the art's known technology.
