Introduce the intrinsically safe flash red tail lamp used in mine. It is mainly used for tail warning signal of underground overhead locomotive and storage battery car when running. It can also be used as fixed warning signal. Red tail lamp has the advantages of reliable performance, reasonable structure, convenient use and long service life. It is one of the preferred equipment to prevent locomotive rear-end collision and remind pedestrians of safety. This product adopts typical unsteady circuit, which greatly simplifies the hardware circuit, reduces the power consumption of the circuit, works for more than 50 hours at a time, improves the reliability of the circuit, reduces the fault of the hardware circuit, and prolongs the life of the battery pack. The flashing red and eye-catching signal is an ideal facility to ensure the operation of Underground Locomotives and personal safety. Note: DHY 0.1/2.4L intrinsically safe flash red tail lamp circuit (hereinafter referred to as red tail lamp) is intrinsically safe for mining, and charging is strictly prohibited in underground. Performance parameter battery pack is composed of two sections (1.2V*2) of rechargeable C4000mAh NIMH battery and cement current limiting resistance series seals of 2_5W. Maximum open circuit voltage of battery pack: 3.0V, maximum short circuit current of battery pack: 1.5A; working voltage range of red tail lamp: DC 2.0-2.8V, rated working voltage 2.4V; maximum working current of red tail lamp: 100mA; flash frequency: (40-plusmn; 10) times/min, intermittent ratio 1:1; signal visible distance: > 20m; use and maintenance of red tail lamp The charger can only be used for DHY 0.1/2.4L type products, and can not be used for other purposes. When charging is needed, the ground charging room is charged with a special charger. The charging time is 9 to 10 hours. When the battery pack is full of electricity, it can be automatically converted to floating charge state, which will not cause overcharge harm to the battery pack. When repairing and replacing batteries and circuit components, it is necessary to replace them according to the model parameters of the original components. It is forbidden to change the model parameters of battery manufacturers and circuit components. Other instructions show that the packaged red tail lamp can be applied to various transportation such as water transportation, land transportation and air transportation under the conditions of avoiding direct sunshine, rain and snow, falling and collision. Way. After packaging, the red tail lamp is allowed to be stored in the warehouse without corrosive gases at ambient temperatures ranging from - 10 to + 40 and the relative humidity is not more than 90%. The storage period is 12 months, and the expiration period should be checked according to the contents of the factory inspection. The transaction indicates that the supply cycle is about one week, payment before delivery.
