Along with the development of telecommunications, more and more higher to index requests such as communication equipment operation ratios, the long-time power failure that power circuit is caused, equipment fault and disaster tolerance or the Capability Requirement of dealing with contingencies also more and more higher; Along with the continuous increase of machine utilization, equipment Years Of Service growing, unpredictalbe fault may occur at any time, the long-time power failure that power network transformation, repairing cause, cause Communication Power Equipment alternating current-direct current to switch frequent, storage battery to discharge for a long time, cause battery backup deficiency of time, communication equipment power down fault happens occasionally.
Utility model content
The purpose of this utility model is to provide a kind of communication power supply isolating and protecting device, accident emergency speed of rushing to repair is accelerated, and can realize the line services such as accumulator cell charging and discharging, cable and switch replacing safely and reliably.
A kind of communication power supply isolating and protecting device, its special feature is: comprise positive terminal unit and negative terminal unit, and wherein positive terminal unit comprises two alligator forceps, is directly connected between these two alligator forceps by wire; Wherein negative terminal unit also comprises two alligator forceps, is connected and on this wire, be in series with silicon rectifier diode and protection fuse respectively between these two alligator forceps by wire.
Wherein silicon rectifier diode adopts reverse breakdown voltage to be greater than the ZP200 silicon rectifier diode of 100V, On current 200A, pressure drop 0.3-0.7V.
Wherein wire adopts 50mm
2multicore annealed copper wire.
The utility model provides a kind of direct current-48V power-supply system multi-function emergency repairing maintain isolation protective device; utilize snap joint, isolating diode, protection fuse, single electrode dc switch and stube cable, realize the insulation blocking when repairing of direct current-48V power-supply system multi-function emergency is safeguarded.
Accompanying drawing explanation
Accompanying drawing 1 is circuit theory schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model provides a kind of communication power supply isolating and protecting device, comprises positive terminal unit and negative terminal unit, and wherein positive terminal unit comprises two alligator forceps, is directly connected between these two alligator forceps by wire; Wherein negative terminal unit also comprises two alligator forceps, is connected and on this wire, be in series with silicon rectifier diode and protection fuse respectively between these two alligator forceps by wire.
Wherein silicon rectifier diode adopts reverse breakdown voltage to be greater than the ZP200 silicon rectifier diode of 100V, On current 200A, pressure drop 0.3-0.7V.Wire adopts 50mm
2multicore annealed copper wire.
Using method of the present utility model and operation principle are:
Because the direct current-48V power supply system for communications adopts plus earth in the utility model, therefore positive terminal unit adopts positive pole cross-line to lead directly to, and two ends are installed snap joint (alligator forceps) and can be completed.Its negative terminal unit negative pole is connected to the ZP200 silicon rectifier diode that reverse breakdown voltage is greater than 100V, On current 200A, pressure drop 0.3-0.7V, utilizes the unilateal conduction characteristic of diode to complete isolation on circuit, stops the reverse power transmission of circuit.Rectifier diode is installed on a heat sink, can uninterrupted steady operation for a long time.Its stube cable adopts the cold-resistant pocket 50mm meeting DL/T879-2004 standard
2multicore annealed copper wire, the alligator forceps of high strength, high snap-in force (can reach more than 20kg) is selected in snap joint, guarantees that joint safety, reliable contacts are to contact place.
This communication equipment direct current-48V power-supply system multifunctional power isolating and protecting device, fill up the power supply system for communications when single supply fault or maintenance, the direct parallel operation emergency first-aid repair of duplicate supply is blank, the danger of load equipment power down when utilizing this device to solve to be equipped with at single supply the maintenance under single group storage battery state, discharge and recharge test, can the emergency repair at each station in flexible reply district, parallel operation increase-volume in the long-time power failure of reply, equipment fault, battery capacity deficiency situation, solves and replaces or visual plant dual-host backup power-supply device complete machine; To control when alternating current input power supplying recovers two high frequency switch powers to the overcharge of batteries; Directly parallel operation repairing fast when happening suddenly natural calamity; Efficiently solve the mutually reciprocal power transmission between power-supply device.
