Abstract

The utility model discloses a dry-type transformer provided with built-in heating devices. The dry-type transformer belongs to the technical field of transformers and comprises a transformer case and a transformer body in the transformer case; the case is provided with the heating devices which are electric heating rods; the four electric heating rods are respectively arranged at the four sides of the transformer case; and every two electric heating rods are oppositely arranged. The dry-type transformer internally provided with the heating devices has the benefit that after the transformer is out of service, the heating devices are started up and used again to improve the insulation resistance of the product to recover the electric performances of the product.

Description

The dry-type transformer of built-in heater
Technical field
The utility model relates to a kind of water filtration device transformer, especially relates to a kind of dry-type transformer of built-in heater.
Background technology
Dry-type transformer is after a period of time of stopping using; Usually owing to it is in moist environment the situation that insulation resistance descends appears; This operation to transformer is disadvantageous; Therefore need to use baking rifle baking coil, to improve the insulation resistance of transformer, this method has certain inconvenience for user's use.
The utility model content
The purpose of the utility model is exactly in order to address the above problem, and a kind of dry-type transformer of built-in heater is provided.
To achieve these goals, the utility model adopts following technical scheme:
A kind of dry-type transformer of built-in heater comprises the transformer housing and is arranged on the inner transformer body of transformer housing that additionally, described transformer housing is provided with heater.
Described heater is an electrically heated rod, and the quantity of electrically heated rod is four, is separately positioned on four sides of transformer housing.
The beneficial effect of the utility model is: the utility model is provided with heater in the transformer housing, thereby before transformer is moved after a period of time of stopping transport once more, starts heater earlier; Release heat reduces the temperature of transformer running environment; Improve the insulation resistance of product, recover the electric property of product, heater adopts electrically heated rod; Cost is low, and is easy to use.The utility model has further strengthened the stability and the reliability of product, has strengthened the reputation of product, the market of having stablized product.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to set forth:
As shown in Figure 1, a kind of dry-type transformer of built-in heater comprises transformer housing 1; Trough 4; The transformer body of in housing 1, installing 3 also is provided with the heater 2 that is used for the heating transformer body on transformer housing 1, described heater 2 adopts electrically heated rod; The quantity of electrically heated rod is four, is separately positioned on four sides of transformer housing 1.
Fixing four electrically heated rods on the inwall of transformer housing; Thereby before transformer is moved after a period of time of stopping transport once more; Connect the electrically heated rod power supply earlier; Reduce the temperature of transformer running environment through the electrically heated rod release heat, improve the insulation resistance of product, recover the electric property of product.
The above is merely the preferred implementation of the utility model, and the protection range of the utility model is not limited in above-mentioned execution mode, and every technical scheme that belongs to the utility model principle all belongs to the protection range of the utility model.For a person skilled in the art, some improvement of under the prerequisite of the principle that does not break away from the utility model, carrying out, these improve the protection range that also should be regarded as the utility model.
