Description

Intelligent power distribution cabinet Technical Field The utility model relates to the technical field of power equipment, in particular to an intelligent power distribution cabinet. Background In modern power systems, intelligent power distribution cabinets serve as core devices for power distribution and control, and serve important tasks for receiving, distributing, controlling and protecting electric energy. The device is widely applied to various fields of industry, business, residence and the like, and the stable operation of the device is directly related to the safety and reliability of power supply. However, in the operation process of the intelligent power distribution cabinet, internal electrical equipment can generate heat during operation, if the heat cannot be timely emitted, the temperature in the cabinet is too high, the performance and the service life of the electrical equipment can be influenced, and even safety accidents can be possibly caused, so that the problem of how to effectively control the temperature in the power distribution cabinet is to be solved urgently. The existing heat dissipation mode mostly adopts a fixed heat dissipation structure, a constant-rotation-speed heat dissipation fan is installed in the cabinet, and forced air flow is used for circulation cooling. However, the fixed wind speed cannot dynamically match the actual heat dissipation requirement, which easily causes energy consumption waste or insufficient heat dissipation. Therefore, the above-described problems are to be solved. Disclosure of utility model The utility model aims to overcome the defects, and the intelligent power distribution cabinet is characterized in that the temperature in the cabinet is monitored in real time through a temperature sensor, the controller dynamically adjusts the rotating speed of a first ventilating fan and the opening state or opening degree of a shutter valve according to a temperature signal, and the second ventilating fan is combined for assisting in heat dissipation, so that the accurate constant control of the temperature in the power distribution cabinet is realized, and the running stability and reliability are improved. The intelligent power distribution cabinet comprises a cabinet body and split doors, wherein the split doors are arranged on the cabinet body, a controller, a ventilation assembly and a temperature sensor are arranged on the upper side of the cabinet body, the ventilation assembly is arranged on two sides of the cabinet body, the temperature sensor is arranged on the inner side wall of the cabinet body and is in signal connection with the controller, the ventilation assembly comprises a pair of shutter valves and a pair of first ventilation fans which are respectively arranged on two sides of the cabinet body, and the controller dynamically maintains the constant temperature in the power distribution cabinet by adjusting the opening or closing or opening of the first ventilation fans and the shutter valves. When the temperature rises, the controller increases the rotation speed of the ventilating fan, opens the shutter valve, increases the air inflow and the air flow rate, and rapidly dissipates heat, and when the temperature decreases, the controller decreases the rotation speed of the ventilating fan, decreases the shutter valve opening, reduces the energy consumption and avoids excessive heat dissipation. Furthermore, in the intelligent power distribution cabinet disclosed by the application, the split door is also provided with the second ventilation fan, and the second ventilation fan is used for assisting in heat dissipation. Under high-load operation scenes (such as high temperature in summer or full load of electrical equipment), the second ventilation fan can provide additional air inlet or exhaust power, so that 'dead angles' of air flow possibly occurring in ventilation of the single two sides are avoided, and even dissipation of heat in the cabinet is ensured. Furthermore, the intelligent power distribution cabinet comprises a valve body frame, a plurality of blades and an operating mechanism, wherein the blades are arranged in parallel, connecting shafts are axially arranged on the blades, a pair of shaft holes are formed in the corresponding valve body frame, two ends of each connecting shaft penetrate through the shaft holes, the blades can rotate around the connecting shafts, and the operating mechanism is arranged on the outer side of the valve body frame and used for driving the blades to synchronously rotate so as to realize opening or closing of the shutter valve and opening adjustment. Through the rotation of the blades around the connecting shaft, the continuous angle adjustment from the complete closing (vertical closing of the blades) to the complete opening (horizontal unfolding of the blades) of the shutter valve is realized, the ventilation quantity can be dynamically adjusted within the range of 0% -100%, the operating me
