[0002] The photovoltaic power generation industry in our country has developed rapidly, which has played a positive role in increasing the energy supply in our country, adjusting the energy structure and protecting the ecological environment. There are a large number of box-type transformers in photovoltaic power stations, which are scattered and have a harsh operating environment. There are many factors that can cause failures during operation. Transformers often fail or even burn out. Therefore, in order to improve the stability and safety of the box-type transformers in photovoltaic power stations, each box transformer should be equipped with a transformer measurement and control protection device to monitor and protect these factors that may cause failures. The existing detection mechanisms cannot prevent the situation of untimely monitoring caused by the power failure of the external power supply, and the heat dissipation effect is poor. Therefore, a monitoring and protection mechanism for a photovoltaic transformer is needed.

[0003] When the existing monitoring and protection mechanism for a photovoltaic transformer is operating, it cannot effectively improve the sustainability of the device's monitoring and protection, and at the same time cannot effectively improve the efficiency of the device's heat dissipation, and cannot improve the convenience of the device's installation and maintenance. For this reason, a monitoring and protection mechanism for a photovoltaic transformer is urgently needed. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a monitoring and protection mechanism for a photovoltaic transformer, so as to solve the problems that when the existing monitoring and protection mechanism for a photovoltaic transformer is in use, it cannot effectively improve the sustainability of the device's monitoring and protection, and at the same time cannot effectively improve the efficiency of the device's heat dissipation, and cannot improve the convenience of the device's installation and maintenance.

A circuit breaker 208 is installed at one end of the distribution board 204. A reserve battery 209 is installed at one end of the distribution board 204. The distribution board 204 and the upper cover 202 form a sliding structure through the chute 203, and the low-voltage protector 207 is threadedly connected to the distribution board 204. The distribution board 204 is snapped into the upper cover 202 through the chute 203 and fixed to the upper cover 202 by a threaded bolt. When the device works, the low-voltage protector 207 and the circuit breaker 208 are used to protect the photovoltaic transformer.

In the case of occasional power outages of the external power supply, the reserve battery 209 effectively provides the electric energy for continuous monitoring to maintain the continuous working state of each instrument and improve the sustainability of the device's monitoring and protection.

[0023] Please refer to Figures 1-4 , a monitoring and protection mechanism for a photovoltaic transformer. A heat dissipation mechanism 3 is installed at one end of the monitoring mechanism 2. The heat dissipation mechanism 3 includes an extension baffle 301, a cooling fan 302 and an air inlet cover 303. An extension baffle 301 is installed at the upper end of the upper cover 202, a cooling fan 302 is installed in the middle of the upper cover 202, and an air inlet cover 303 is installed at one end of the extension baffle 301.

The side seat plates 401 are symmetrically arranged with respect to the central axis of the protection box 1. Move the moving plate 403 within the slideway 402, and clamp the protection box 1 on the upper end of the photovoltaic transformer through the side seat plates 401 and the moving plates 403. Then use bolts to fix the positions of the side seat plates 401 and the moving plates 403 on the photovoltaic transformer. The installation is convenient.

[0025] Working principle: When in use, first move the moving plate 403 within the slideway 402, and clamp the protection box 1 on the upper end of the photovoltaic transformer through the side seat plates 401 and the moving plates 403. Then use bolts to fix the positions of the side seat plates 401 and the moving plates 403 on the photovoltaic transformer. The installation is convenient. Then start the cooling fan 302 to blow the outside air into the protection box 1 from the upper end to the lower end through the air inlet cover 303 and the extension baffle 301. The extension baffle 301 prevents water from entering the protection box 1 from the air inlet cover 303, reduces the temperature inside the protection box 1, and enables the hot air to quickly discharge from the diagonal air outlets on both sides of the protection box 1, improving the efficiency of the device's heat dissipation. And the distribution board 204 is clamped into the upper cover 202 through the chute 203 and fixed on the upper cover 202 through threaded bolts. When the device is working, the photovoltaic transformer is protected by the low-voltage protector 207 and the circuit breaker 208. At the same time, the data monitored by the current and voltage monitor 206 can be recorded by the gateway 205 in time and transmitted to the computer terminal for recording and monitoring. In the case of occasional power outages in the external power supply, the reserve battery 209 effectively provides the electric energy for continuous monitoring to maintain the continuous working state of each instrument, improving the sustainability of the device's monitoring and protection. And the internal working instruments of the protection box 1 can be observed through the tempered glass 201. When maintenance is needed, the bolts on the upper cover 202 can be removed, and the distribution board 204 can be directly pulled out from the protection box 1 for maintenance work, improving the convenience of the device's installation and maintenance.
