Description
Technical field
The utility model belongs to intelligent power apparatus field, specifically, relates to a kind of base station intelligent power case.
Background technology
Mobile communication base station equipment adopts DC power-supply system that the energy is provided.All adopt at present combined frame power-supply system, wear the DC uninterrupted electric power system of the lead-acid batteries composition of online floating charge power supply system, its supply power voltage is-48V.The output current capacity of rectifier is considered depending on host requirements, batteries charging demand, uninterrupted power supply nargin demand etc.
Combined frame power-supply system, along with being widely used, is all had large improvement in its function, performance and technical indicator at present, and its main feature is: taken into full account the demand that volume is little, lightweight, facilitate I&M; Standardization, modularization, rectification module can hot plugs; Adapt to voltage range wide; The demands such as lightning protection anti-surge have been taken into full account; All support power-supply system to carry out the unattended function demand of back-stage management; Considered as far as possible the management function to batteries; Taken into full account in particular cases once and second demand; Other safety and reliability design are as antiseismic ability etc.Different manufactories device select and manufacturing technology level on, there is some difference, causes stability and the reliability of equipment operation there are differences, extremely important for the maintenance work of Switching Power Supply.The low-voltage short-circuiting device of being furnished with in equipment generally includes band creepage protection function and is not with creepage protection function.The prevention of electric shock main object difference of the two, the former protects personal safety, and the latter protects electric equipment.
But in existing such scheme, " test " button on leakage switch need to be manually pressed in the test of traditional leakage switch, switch trip illustrates that creepage protection function is normal.After pressing " test " button, switch does not trip, and illustrates that this earth leakage circuit-breaker lost efficacy.In operating process, can cause power failure, be unfavorable for that communication runs well with base station.Therefore in practical operation, have and exceed 90% the user self check of periodically not threading off, cause traditional leakage switch to increase in cisco unity malfunction shape probability of state, bring potential safety hazard.
Switching Power Supply, because the reason of design and components and parts exists equipment leakage to a certain degree conventionally, easily causes earth leakage protective device tripping operation, because most of base stations are in unattended operation state, needs artificial reclosing to cause maintenance cost high after tripping operation.In actual conditions, there is the phenomenon of artificially earth leakage protective being removed.Cause personal safety hidden danger and electric disaster hidden-trouble.For the base station that there is no dedicated transformer, if earth leakage circuit-breaker is not installed, once there is electric leakage accident, can cause the earth leakage circuit-breaker of higher level's distribution system to trip, will cause wider line outage, bring more serious loss.
Statistics shows, the ratio of the low-voltage circuit breaker tripping operation that permanent fault causes is no more than 10%, for residual current circuit breaker, cause the reason of its misoperation a lot, the surge voltage causing in the line as thunder and lightning, the high order harmonic component that electronic equipment causes in the line, long lead capacitance current over the ground etc.Occurring to need manual maintenance after misoperation tripping operation, for unattended base station, maintenance cost and time cost are higher.
Lightning surge protective device in Switching Power Supply shields when lightning wave occurs, and protection equipment is not damaged.The lightning current of releasing over the ground when thunderbolt occurs of lightning protection device; and earth leakage protective device is responsible for monitoring electric current over the ground; once lightning protection device action; earth leakage protective device just may trip and make lightning protection device depart from circuit; lose protective effect; while there is follow-up thunderbolt, equipment may punch through damage, even causes fire.Especially in area with more lightning activities or the base station of thunderstorm season, more easily there is thunderbolt switch trip event.Increase maintenance cost, the equipment that affects runs well.
