Description
Technical field
The utility model relates to a kind of power equipment, is specifically related to a kind of high efficiency and heat radiation transformer.
Background technology
transformer utilizes the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core.In electric equipment and radio-circuit, be commonly used for buck/boost, matched impedance, Secure isolation etc.In generator, be no matter coil movement by magnetic field or Movement in Magnetic Field by fixed coil, all can in coil induced potential, these two kinds of situations, the value of magnetic flux is all constant, but has variation with the magnetic flux quantity that coil is cross-linked mutually, and this is the principle of mutual induction.Transformer be exactly one utilize undesirable mutual electromagnetic inductance should, the device of voltage of transformation, electric current and impedance.The function of transformer mainly contains: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing (magnetic saturation transformer) etc.
Loss is produced always during transformer electric energy transmitting, this loss mainly contains copper loss and iron loss, copper loss and iron loss all can produce amount of heat, general civilian transformer all adopts at inside transformer perfusion transformer oil to take away this part heat, this part heat is circulated in the heat pipe of transformer case outside by conduction oil and dispels the heat, when peak of power consumption in summer, transformer temperature sharply raises, too high temperature makes again transformer internal resistance raise, further aggravation heating, transformer work is made relatively to become unstable, therefore heat radiation is a large key element of transformer steady operation.
Utility model content
The purpose of this utility model is that the inside transformer solving the existence of above-mentioned prior art cannot realize timely heat radiation, the deficiency that radiating effect is poor, provides a kind of high efficiency and heat radiation transformer of perfect heat-dissipating.
The utility model is achieved through the following technical solutions:
High efficiency and heat radiation transformer, special character is to comprise transformer shell 1, is provided with coil 2 in transformer shell 1, and described coil 2 one end is connected with input lead, and the other end is connected with output lead; Described transformer shell 1 top is provided with thermal insulation layer 3, blower fan 4 is installed bottom transformer shell 1, and is provided with the blast pipe 5 of blower fan 4 two ends connection in bottom, blast pipe 5 is equipped with Non-return air valve 6, to ensure air pressure comparatively balanced in blast pipe, be beneficial to the proper heat reduction of transformer.The exhaust outlet place at described blast pipe 5 two ends is provided with the exhaust duct 7 of air draft vertically upward, spiral water conservancy diversion lines 7-1 is provided with in exhaust duct 7, and the internal diameter of exhaust duct 7 increases from the bottom to top gradually, cold wind forms helical flow under the effect of spirality water conservancy diversion lines, during flowing and tube wall tangent, improve the radiating efficiency to transformer shell.Described transformer shell 1 inside is provided with temperature sensor 8 and comparator 9, alarm 10 is installed outside thermal insulation layer 3, temperature sensor 8 is all connected with comparator 9 with alarm 10, to compare real time temperature and preset temperature, and is greater than preset temperature alarm at real time temperature.
Preferably, described blower fan 4 arranged outside has screen pack 4-1, can prevent larger particles impurity from entering blower fan, affects the normal work of blower fan.
Further, owing to inevitably entering liquid or granule foreign in blast pipe, bottom described blast pipe 5, be also provided with outlet 5-1.
This high efficiency and heat radiation transformer, is equipped with the exhaust duct of blower fan and spirality water conservancy diversion lines, improves the radiating efficiency of transformer.Simultaneously, the connection of transformer shell inside and outside is supporting temperature sensor, comparator and alarm, can to staff and alarm, thus facilitate staff to take corresponding measure to lower the temperature in time when inside transformer real time temperature is greater than preset temperature, effectively ensure the safe operation of transformer.
