Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinet safety protection, in particular to a low-voltage power distribution cabinet with a pressure relief protection structure. Background Art

[0002] Low voltage distribution cabinet is a kind of power distribution equipment used in power system, which is mainly used to introduce electric energy from high voltage transmission line to user terminal to realize the distribution and control of electric energy. It is usually composed of motor control equipment, power meter, protection device, circuit breaker, etc.

[0003] For example, the Chinese utility model patent with announcement number CN219833401U discloses a low-voltage power distribution cabinet, including a cabinet body and a base. When in use, an alarm is set. When the cabinet door is opened illegally, the pressure sensing switch will control the alarm to sound an alarm, thereby scaring off the illegal operator and reminding the staff in time. Moreover, when the alarm sounds an alarm, the plug is inserted into the slot, and the cabinet door cannot be opened further, so as to prevent the cabinet door from being easily opened.

[0004] The above solution has the following problems: when the electrical equipment in the distribution cabinet is used for a long time, electrical pressure will be generated inside. Since the distribution cabinet is not equipped with a pressure relief structure, the long-term electrical pressure may cause equipment damage or safety hazards. In serious cases, it may cause fire and explosion inside the distribution cabinet, causing a safety accident.

[0005] Therefore, we propose a low-voltage distribution cabinet with a pressure relief protection structure to solve the above-mentioned problems. Utility Model Content

[0012] By adopting the above technical solution, the pressure in the upper and lower chambers can be quickly transmitted through the pressure relief pipe when the pressure relief valve is opened.

[0013] As a preferred technical solution of the present utility model, a pressure monitoring sensor is arranged at the top of the upper chamber; the pressure monitoring sensor is fixedly connected to the top of the upper chamber.

[0014] The above technical solution can be used to understand the internal pressure of the distribution cabinet in real time through the pressure monitoring sensor. When the internal pressure exceeds the standard, the excess signal is transmitted to the pressure relief valve, so that the pressure relief valve opens to relieve the pressure in the cavity.

[0016] The above technical solution can separate the chambers through the inner partition to improve space utilization; the overload protection device can automatically cut off the power supply when the current exceeds the rated value to avoid safety accidents caused by overload of the distribution cabinet.

[0017] As a preferred technical solution of the utility model, a data observation window is provided at the upper right corner of the cabinet door; the data observation window is made of a transparent, high-temperature-resistant, high-strength material.

[0018] By adopting the above technical solution, the data displayed on the internal display screen can be observed through the data observation window, and various data in the cabinet can be accurately grasped.

[0019] As a preferred technical solution of the utility model, a display screen placement cavity is separated at the upper right end of the upper chamber; the display screen placement cavity is fixedly connected to the cabinet; a data display screen is arranged inside the display screen placement cavity; the data display screen is fixedly installed inside the display screen placement cavity.
