Description

Technical Field

[0001] The invention relates to the technical field of electric power equipment, and in particular to a high and low voltage switch cabinet with real-time monitoring and alarm functions. Background Art

[0002] As the name suggests, high and low voltage switchgear is equipment for connecting high-voltage or low-voltage cables. Generally, power supply bureaus and substations use high-voltage cabinets, which are then stepped down by transformers and then transferred to low-voltage cabinets. The low-voltage cabinets are then transferred to distribution boxes for various electricity users. What is inside is nothing more than some protective devices such as switches and circuit breakers assembled into one electrical equipment.

[0003] Common high and low voltage switchgear has the disadvantages of complex structure, high product cost, weak safety, etc. The equipment has low intelligence and automation. Once the equipment fails, it will threaten the safety of people and equipment. The wiring connection method used by traditional monitoring means makes the signal extremely susceptible to interference during the transmission process, making the monitoring results inaccurate or even causing serious deviations. It cannot play the role of real-time monitoring and alarm. The monitoring device does not have adjustable functions, resulting in low efficiency.

[0004] In addition, some high and low voltage switch cabinets are equipped with fire extinguishing sprinklers. When a fire occurs inside the cabinet due to a short circuit or other reasons, the fire can be extinguished by the fire extinguishing sprinklers. Since the current fire extinguishing sprinklers are directly fixed to the inside of the cabinet and have a relatively simple structure, and since there are many types of electrical equipment inside the high and low voltage switch cabinets, and they are fixed in a superimposed manner, and protective elements are provided between the electrical equipment, the fixed fire extinguishing sprinklers are easily blocked by the superimposed electrical equipment and protective elements when spraying, and cannot achieve a more comprehensive fire extinguishing effect.

The light alarm 31 and the sound alarm 32 are arranged in parallel on the outer surface of the cabinet door 12. When the temperature inside the cabinet 10 reaches the detection range temperature of the temperature sensor 21, the light alarm 31 and the sound alarm 32 alarm; when the smoke concentration inside the cabinet 10 reaches the detection range concentration of the smoke sensor 22, the light alarm 31 and the sound alarm 32 alarm. In some embodiments, the anti-theft sensor may be an infrared sensor, which is arranged on the cabinet door 12 and is electrically connected to the anti-theft lock. When someone wants to forcefully open the cabinet door 12, the anti-theft sensor senses and transmits information to the light alarm 31 and the sound alarm 32 for alarm.
