Description
Technical field
This utility model relates to transformer field, is specifically related to a kind of oil immersed type combination transformer case.
Background technology
Transformer is also called instrument transformator, is the general designation of current transformer and voltage transformer.High voltage can become low-voltage, big electric current becomes small area analysis, is used for measuring or protecting system.High voltage or big electric current scaling transformation are mainly become normal low voltage 100V or standard small area analysis 5A or 1A by its function, refer both to rated value, in order to realize measuring instruments, protection equipment and the standardization of automatic controlling device, miniaturization.Transformer may further be used to separate high-voltage system simultaneously, to ensure the safety of the person and equipment.Wherein combined instrument transformer is combined by current transformer and voltage transformer, is installed on High-voltage measuring box, cabinet more, is used as metering electric energy or is used as the power supply of electrical equipment protective relaying device.The combined instrument transformer of prior art mostly is oil immersed type, but the oil immersed type of prior art has the risk of leakage of oil thus causes pollution and the rising of transformer temperature of environment, causes mulual inductor malfunction.And oil immersion type mutual-inductor is operationally, oil temperature can raise, thus causes and pressure in case becomes big, if pressure release in time and heat radiation the damage of fuel tank can not can be caused.
Utility model content
The problem existed for prior art, this utility model provides a kind of oil immersed type combination transformer case, and this case can play beyond thought radiating effect, increase the service life of oil immersed type combination transformer, and conveniently maintenance, meanwhile, take notice of the pollution not resulting in environment under the oil condition that leaks outside.
Concrete technical scheme is as follows:
A kind of oil immersed type combination transformer case, including casing, case lid, oil-containing groove, described casing top is provided with case lid, described case lid is jagged thermal conductive metal plate, described oil-containing groove is the groove of top end opening, combination transformer is placed in described oil-containing groove, and the base, the left and right sides of described oil-containing groove is slidably connected can be with the guide rail of slide anteroposterior, and described guide rail is fixed on the bottom of described casing；
Preferably, described casing is laid with solar power supply apparatus；
Preferably, the sidewall of described casing being fixed with fan, described fan is electrically connected with described solar power supply apparatus；
Preferably, there is air vent the side of described casing；
