Appearance patent application number: 201320168574.0 product utility model patent application number: 201330103420.9 This product appearance and utility model patents two. I. Introduction: Rack intelligent mine case is in accordance with national and industry standards development and design of mine, and mine me with many years of experience in the design, specializing in lightning protection of electrical equipment for various sectors of the cabinet, the cabinet will not only have to All electrical equipment provides fine surge protection, along with the power of the cabinet where the environment (buildings, floors) to provide a power protection features. It counts with lightning, power indicator, mine deterioration instructions, remote output function, rackmount structure, rational layout, easy wiring, the overall appearance, practical features. Second, the scope: Lightning Surge protective effect rack intelligent lightning boxes widely used in communications, weather, traffic, telecommunications, power, petrochemical, housing, railways, finance, securities, government, military, schools, and other fields, play . Third, Features: ◆ lightning box with B, C levels of protection, both B-class large flow capacity, but also has a C-class level of protection; ◆ PDU power distribution unit provides 5-way power socket in the equipment; ◆ differential mode and common mode power supply with full protection, protective effect; ◆ energy saving, environmental protection, easy installation; ◆ has a power indicator of each phase, mine deterioration instructions and lightning counting function; ◆ has a remote signal output; ◆ nanosecond response rate; ◆ Core components adopt domestic and international famous brands, superior performance; four, works at normal operating voltage, lightning protection module in a high impedance state, does not affect the normal operation of the circuit, lightning box lightning indicates green light (power Lightning indication indicating integration). When the line due to lightning or switching from transient pulse overvoltage arrester module quickly turned in the nanosecond time and lightning counter shows the cumulative count of the number of over-voltage short circuit to ground discharge, when the pulse overvoltage After the disappearance, lightning protection module and automatically restore high-impedance state, without affecting the user power supply. When the surge voltage is too large, flow capacity exceeds the maximum, so that the deterioration of lightning protection module, the module overcurrent and overheating overheat trip device automatically disconnects the mine module circuit protection circuit is not affected power supply and prevent fires ; at this mine indicator turns red, indicating SPD fault, to remind users to change.
