Description

a transformer box

technical field

The invention relates to the field of electric equipment, in particular to a transformer box.

Background technique

A transformer box is a box in a power system where the voltage and current of electric energy are transformed, concentrated and distributed. The original substation box has poor heat dissipation performance, and it is easy to burn the substation box during the peak period of electricity consumption and when the temperature is too high, which will cause large economic losses and bring many troubles to people's lives. In order to ensure the quality of electric energy As well as the safety of equipment, voltage adjustment, power flow (flow direction and distribution of voltage, current and power in each node and branch in the power system) control and protection of transmission and distribution lines and main electrical equipment are also required in the substation box , mainly used to protect power facilities. However, during the use of the transformer box, due to the operation of the equipment, a lot of heat will be generated, and even the internal equipment and lines will burn and smoke, aging, smoke, sparks, etc., and because of the material and structure of the transformer box , which cannot be observed externally, so we propose a transformer box.

Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a transformer box.

In order to achieve the above object, the present invention is achieved through the following technical solutions: a transformer box, including a box body, an alarm, an observation window, an electromagnet, a water jacket, a vibration sensor, a water pump, a relay switch, a photothermal sensor, Temperature sensor, water tank, exhaust fan, suction fan, high-voltage terminal, characterized in that: the alarm is fixed on the top surface of the box, the observation windows are respectively located on the left and right sides of the box, and the electromagnet absorbs the thin iron plate to cover The observation window, the water jacket is placed in parallel, the vibration sensor is located under the observation window on the left side of the box, the water pump is located in the water tank, the relay switch is located on the front surface of the box, and the photothermal sensor is located on the box On the surface, the temperature sensor is placed between the water jackets, and the water tank is located below the box; one side of the box is provided with a suction fan and an exhaust fan is installed on the top; the top of the box is provided with a high-voltage terminal.

Preferably, an electromagnet is provided at each of the four corners of the observation window.

Preferably, there are two observation windows, which are respectively located on the left and right sides.

Preferably, the electromagnet is connected with a photothermal sensor.

Preferably, there are three water jackets arranged in parallel, and two temperature sensors are arranged between every two water jackets.

Preferably, the water pump is connected in series with a relay switch.

Preferably, the high-voltage terminal is made of insulating material.

Compared with the prior art, the beneficial effect of the present invention is: the transformer box is equipped with a suction fan on one side of the transformer and an exhaust fan on its top to form a heat dissipation channel for the cold air to enter and the hot air to flow out, greatly improving The heat dissipation performance of the substation box improves the operating speed and service life of the power distribution equipment in the substation box. The substation box is equipped with multiple water jackets and temperature sensors. The temperature inside the electric box greatly improves the heat dissipation of the electric box, thereby improving its service life. The electric box is also equipped with a photothermal sensor and an alarm system. In the event of sparks and other conditions, the electromagnet loses its electromagnetic effect, activates the alarm system, opens the observation window, and improves the safety factor of equipment and personnel in emergencies.

detailed description

In order to realize the technical means, creative features, goals and effects of the present invention to be easily understood, the present invention will be further described below in conjunction with specific embodiments.

Please refer to Figure 1-2, the present invention provides a technical solution: a transformer box, including a box body 1, an alarm 2, an observation window 3, an electromagnet 4, a water jacket 5, a vibration sensor 6, a water pump 7, and a relay Switch 8, photothermal sensor 9, temperature sensor 10, water tank 11, exhaust fan 12, suction fan 13, high-voltage terminal 14, the alarm 2 is fixed on the top surface of the box body 1, and the observation windows 3 are respectively located in the box body 1 On the left and right sides, the electromagnet 4 absorbs a thin iron plate to cover the observation window 3, and the four corners of the observation window 3 are provided with an electromagnet 4, and there are three water jackets 5, which are placed in parallel, and the vibration The sensor 6 is located below the observation window 3 on the left side of the box body 1, the water pump 7 is located in the water tank 11, the relay switch 8 is located on the front surface of the box body 1, the water pump 7 is connected in series with the relay switch 8, and the photothermal sensor 9 is located on the upper surface of the box body 1, and there are two temperature sensors 10, which are placed between every two water jackets 5 respectively. The water tank 11 is located below the box body 1 . One side of the box body 1 is provided with a suction fan 13 and an exhaust fan 12 is installed on the top thereof; the above box body 1 is provided with a high-voltage terminal 14, and the high-voltage terminal 14 is made of insulating material.

When in use, when the temperature is higher than the set temperature, the temperature sensor 10 acts, the relay switch 8 opens through the series circuit, the water pump 7 works, the water circulates in the water jacket 5, and the temperature is lowered. When the temperature is lower than the set temperature, the temperature sensor 10 function, close the relay switch 8, and the water pump 7 stops working. When sparks or smoke appear, the photothermal sensor 9 acts on the electromagnet 4, making it lose its electromagnetic effect, causing the thin iron plate to fall, and the observation window 3 is opened to trigger the vibration sensor at the same time 6. As a result, the alarm 2 works, which not only improves the heat dissipation of the transformer box, increases the safety factor, and prolongs its service life, but also can detect emergencies as quickly as possible, greatly reducing losses in all aspects.
