Description
Technical Field
[0001] The utility model belongs to the technical field of box-type transformers, and in particular relates to a high-safety box-type transformer with leakage protection. Background Art
[0002] Box-type substations are widely used in power distribution projects such as industrial and mining enterprises, municipal construction, and residential electricity. They include boxes, doors, internal transformers, and high and low voltage power distribution equipment. In order to reduce the manufacturing cost of box-type substations, box-type substations are designed to be relatively compact, and their internal space is extremely limited. They are divided into high-voltage room, low-voltage room, and transformer room. The transformer is placed in the transformer room. The transformer is a device that converts AC voltage, current, and impedance. When AC current passes through the primary coil, AC magnetic flux is generated in the iron core (or magnetic core), so that voltage (or current) is induced in the secondary coil. The transformer consists of an iron core (or magnetic core) and a coil. The coil has two or more windings, of which the winding connected to the power supply is called the primary coil, and the remaining windings are called secondary coils.
[0003] In the prior art, general box-type transformers generally adopt the method of opening heat dissipation holes to dissipate heat, and the heat dissipation and ventilation effects are good. However, when the temperature alternates between summer and winter, water droplets will be generated inside the box-type transformer due to the alternation of cold and hot air. The water droplets will cause the internal electrical components to become damp and age, resulting in leakage. When leakage occurs, the danger cannot be eliminated in time, which may cause harm to the staff. Therefore, a high-safety box-type transformer with leakage protection is needed to solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to provide a high-safety box-type transformer with leakage protection to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-safety box-type transformer with leakage protection, comprising a device body, a distribution cabinet is arranged in the device body, a protection component is arranged in the distribution cabinet, the protection component comprises a radiator, a heat dissipation copper tube is arranged in the radiator, a movable groove is opened in the distribution cabinet, an electric push rod is arranged in the movable groove, a pressure plate is arranged at the bottom end of the electric push rod, and a temperature sensor is arranged in the distribution cabinet.

At the same time, the temperature in the distribution cabinet is detected by the temperature sensor, so as to control the opening and closing of the radiator, so that the temperature in the distribution cabinet is consistent with the outside temperature, which can prevent the generation of water droplets in the distribution cabinet. When leakage is detected, the electric push rod will automatically start, and the working electric push rod will drive the pressure plate to move downward, and the downward moving pressure plate will press the main power switch, thereby turning off the main power.
[0007] As a preferred embodiment, a base is provided on the lower surface of the device body, and the number of the bases is four and distributed in a rectangular array.
[0008] The base can provide a shock-absorbing effect on the device body, thereby preventing the bottom of the device body from directly contacting the ground during installation, thereby preventing the device body from being deformed.
[0009] As a preferred embodiment, a main cabinet door is provided on the front of the device body, and an exhaust port is opened in the main cabinet door.
[0010] By providing the exhaust port, the hot air generated in the device body can be discharged, preventing the hot air in the device body from being unable to dissipate.
[0011] As a preferred embodiment, a handle is provided on the front of the main cabinet door, a partition is provided in the device body, a transformer is provided in the device body, and the transformer is located on one side of the partition.
[0012] By providing a partition, the transformer can be separated from the distribution cabinet to prevent the heat generated by the transformer from affecting the distribution cabinet.

[0015] As a preferred implementation, the heat dissipation copper tube is located on the back of the distribution board, the other end of the pressure plate is located above the main power switch, and the temperature sensor is located above the distribution board.
[0016] By providing a temperature sensor, the temperature of the distribution board is detected by the temperature sensor. When the temperature is too high, the radiator is turned on to dissipate heat. When the temperature is consistent with the outside temperature, the radiator is turned off to make the temperature inside the distribution cabinet consistent with the outside temperature. This can prevent water droplets from forming in the distribution cabinet, and when the radiator is turned off, it can achieve energy-saving effects.
[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] The utility model is provided with a radiator, a heat dissipation copper tube, a movable groove, an electric push rod, a pressure plate and a temperature sensor. When working, the opening and closing of the radiator is controlled by the temperature detected by the temperature sensor, so that the temperature in the distribution cabinet is consistent with the outside temperature. When leakage is detected, the electric push rod will start automatically, drive the pressure plate to press the main power switch to turn off the main power. The device can prevent the problem of water droplets generated inside and causing leakage, and when leakage occurs, the main power can be turned off in time to prevent workers from being injured.
