Abstract
The utility model discloses an automatic start-stop device for an external fan of a self-cooled transformer, and the device consists of a rack, a refrigerating fan, a temperature sensor, a temperature control switch, an alarm, a current and voltage detector, a rotating speed relay, and an emergency stop switch. The rack is disposed on a transformer housing. The refrigerating fan, the temperature control switch, the alarm, the current and voltage detector and the emergency stop switch are all disposed on the rack. The temperature sensor is disposed on the transformer housing, and is electrically connected with the temperature control switch. The current and voltage detector is electrically connected with a binding post of a transformer. The rotating speed relay is disposed on a rotating shaft of the refrigerating fan. The device provided by the utility model is high in degree of automation, is high in operation precision, is stable and reliable in operation of a system, can effectively decrease the external temperature of the transformer, effectively reduces the energy consumption of the operation of the fan, has the functions of cooling the fan, monitoring operating status of the fan and giving an alarm, and prevent the temperature decrease of the transformer from failing caused by insufficient power or a fault.
Description
Technical field
The utility model relates to the additional fan of a kind of self-cooled transformer from starting and stopping mechanism, belongs to technical field of automatic control.
Background technique
Transformer is in operation, can produce a large amount of heats, in addition when ambient temperature is higher, transformer temperature rise phenomenon is even more serious, as can not be in time heat discharged, the normal operation of transformer will be affected, even cause transformer to damage, thereby serious harm power supply system is normally moved, although the transformer self using is at present with certain heat sinking function, but be far not enough to reach the requirement of guaranteeing the normal operation of transformer, therefore in use often can take to utilize external fan etc. to carry out external forced cooling to transformer, but utilizing fan in transformer cooling at present, owing to lacking professional fan start-stop control apparatus, only rely on the start-stop operation of manual operation fan, very easily cause the transformer causing not in time because of fan start-stop to cross cause thermal damage or the too high disadvantage of fan energy consumption, cause utilizing fan for cooling job run reliability not high, when being in operation, fan can not find in time to get rid of while breaking down simultaneously, further reduced fan reliability of operation, therefore, fan start-stop control apparatus high in the urgent need to a kind of automatic operating degree and system run all right is used for transformer to implement external forced cooling.
Summary of the invention
The utility model object is just to overcome above-mentioned deficiency, provides the additional fan of a kind of self-cooled transformer from starting and stopping mechanism.
For achieving the above object, the utility model is to be achieved through the following technical solutions:
The additional fan of a kind of self-cooled transformer is from starting and stopping mechanism, by frame, refrigerating fan, temperature transducer, temperature detect switch (TDS), alarm, current/voltage detector, tachometric relay and emergency stop switch form, described frame is arranged on transformer case, described refrigerating fan, temperature detect switch (TDS), alarm, current/voltage detector and emergency stop switch are installed in frame, described temperature transducer is arranged on transformer case and with temperature detect switch (TDS) and is electrically connected, current/voltage detector and transformer binding post electrical connection, described temperature detect switch (TDS), current/voltage detector and alarm electrical connection, described alarm is another to be electrically connected with emergency stop switch, described tachometric relay is separately arranged on refrigerating fan running shaft, described current/voltage detector is another to be electrically connected with refrigerating fan motor coil.
The utlity model has fan start-stop auto-control degree and running precision high, and the reliable feature of system run all right, when effectively transformer being carried out outside cooling, effectively reduce fan operation energy consumption, simultaneously this novelly also possesses the function that fan for cooling effect and fan running state are monitored and reported to the police, when fan for cooling effect reduces, when too high the and fan self of transformer temperature rise breaks down, early warning in time, has avoided because of the transformer that plant capacity deficiency or fault etc. the cause failed phenomenon of lowering the temperature.
Accompanying drawing explanation
Fig. 1 is this new structure schematic diagram.
Embodiment
