For solving the problems of the technologies described above, the utility model embodiment provides a kind of current transformer, and to realize the efficiently radiates heat to current transformer, technical scheme is as follows:
A kind of current transformer is provided with dividing plate in the cabinet, be high heater members district and the low heater members district that is isolated from each other with separated by spaces in the cabinet; In high heater members district, be provided with the high heating power device that heating power is greater than or equal to predetermined threshold value, in low heater members district, be provided with the low heating power device that heating power is lower than predetermined threshold value; Cabinet upper and lower in described high heater members district is respectively arranged with first air outlet and first air inlet, and the described first air outlet place also is provided with first blower fan; Cabinet upper and lower in described low heater members district is respectively arranged with second air outlet and second air inlet, and the described second air outlet place also is provided with second blower fan.
Preferably, described high heating power device comprises: power model.
Preferably, described high heater members district is positioned at the rear side of current transformer, and described low heater members district is positioned at the front side of current transformer.
Preferably, described dividing plate is a polycarbonate plate.
Preferably, in the described power model, version and mainboard are installed radiator is wrapped up, form the inner air channel of power model.
Preferably, the below of described first blower fan also is provided with wind collecting unit.
By using above technical scheme, a kind of current transformer that the utility model provides can be provided with high and low two kinds of different heater members districts according to the heating situation of device in the current transformer in current transformer.Each hot zone has independent air channel and is equipped with exclusive blower fan to carry out radiating treatment, thereby interferes with each other between the lower device of avoided dispelling the heat higher device and heat radiation, has improved radiating effect, has guaranteed the safe operation of current transformer.
