Cooling machine transformer box

Abstract

The invention discloses a cooling machine transformer box. The structure of the cooling machine transformer box comprises a box body, a base, a winding, a clamping plate, a current limiting protectiondevice, an insulator, an iron core and a plug. The box body is integrally formed, the cooling machine transformer box is provided with the current limiting protection device which is connected to thewinding through a connecting member in one end of a current limiting device body, then current enters inside and the magnitude of the current of a connected branch can be limited by a resistor, the current distribution of each coil is changed in the time of a fault, so a limiting coil presents a large impedance to achieve a current limiting function, the power supply is cut off with the cooperation of a circuit breaker, a current which exceeds a rated current is prevented from passing a load, a cooling machine does not work in a state of exceeding the rated current, the fault current is limited, the automatic set is carried out after a fault line is disconnected or the fault disappears, the safety of the cooling machine is effectively protected, and the service life of the cooling machineis prolonged.

Description

Technical field [0001] The invention is a cooler transformer box, belonging to the technical field of transformer equipment. Background technique [0002] A transformer is an electrical equipment that converts electrical energy. It can convert a voltage and current of AC power into another voltage and current of the same frequency. It is used in almost all electronic products. [0003] The prior art discloses a cooler transformer box with an application number of CN201320262165.7, comprising a transformer box and a transformer, the transformer is installed in the transformer box, and a refrigerator is provided outside the transformer box, and the refrigerator is connected to a blower mouth. When the transformer box of this type of cooler is in operation, the refrigerator is started according to the situation, and cold air is blown into the transformer box through the blowing port to cool the transformer. The cooling effect is good, and the normal operation of the transformer is gu...
