Kdq1140-c mine flameproof dual power switch control box-product details

Product introduction
This device is suitable for 50 / 60Hz, 1140 / 660 / 127V (AC) power supply of various voltage levels. It is a new type of double power automatic switching device with intelligent control system. When the equipment works normally, when the main power supply is suddenly cut off, it will automatically switch to the secondary power supply; when the main power supply is restored, it will automatically switch back to the main power supply, always giving priority to the main power supply, so as to realize the automatic switching between the main and auxiliary double circuit power supply, provide stable and reliable power supply for the load, and ensure the production efficiency and safety.
Product features
This product is equipped with manual switching and output disconnection functions, which is convenient for maintenance personnel to know whether the equipment is in normal working state at any time. In addition, through the output disconnect button, it is convenient to carry out power-off maintenance of the access load equipment. It has the advantages of novel design, high degree of automation, wide application range, reducing the accident rate and ensuring the safety of mine work. This product has leakage, short circuit, overload and other protection functions.
Scope of application
This series of products can provide stable double power supply of 1140 / 660 / 127 / 0-36v (AC) and other voltage levels for the load, which is generally applicable to underground monitoring substation, automatic damper, mine anti sports car, substation, etc.

product mix
The device is composed of explosion-proof control box and control circuit.
The explosion-proof box is divided into control chamber and wiring chamber. The upper part is the wiring chamber, and the lower part is the control chamber. The structure is humanized, and the wiring is safe and easy to use. The front and side of the box are respectively designed with operation units such as operation status observation window, button and on-off switch.
working principle
Explosion proof terminal is set in the connection chamber of the control box, and the external main and auxiliary power supplies are connected to the control box through the connection cavity. If the main and auxiliary power supplies are powered on at the same time, the control part always maintains the principle of main circuit priority, and the main circuit supplies power for the load. Under normal working condition, the main controller judges the selection of main and secondary circuits by real-time monitoring the on-off status of main and auxiliary power supply. When the main power supply is cut off, it automatically switches to the secondary power supply; after the main power supply is restored, it automatically switches back to the main power supply, thus realizing the automatic switching function of dual power supply. If the secondary power supply is disconnected after the main power supply is powered on, the secondary power supply lamp will go out until the auxiliary power supply is back on. In addition, the device is designed with humanized functions such as working state indication, manual switching and output disconnection, which is practical, convenient and fast. By pressing the manual switch button, the main and auxiliary power supply can be switched without disconnecting the power supply of the main and auxiliary circuits.
