Description
[technical field]
The utility model relates to mining power supply unit technical field, specifically a kind of mine flameproof and intrinsic safety type power supply box.
[background technology]
UPS(Uninterruptible Power System), it is uninterrupted power supply, it is a kind of energy storage device that contains, be the uninterrupted power supply of the constant voltage constant frequency of chief component with the inverter, be mainly used in providing continual supply of electric power to single computer, computer network system or other power electronic equipment.When civil power input just often, UPS is supplied to load to use after with the civil power voltage stabilizing, the UPS of this moment is exactly an electric main pressurizer, it also charges to self-contained battery simultaneously; When civil power interrupted (accident interruption), UPS was immediately with the electric energy of self-contained battery, and the method by the inversion conversion continues the alternating current of supply specific standard to load, made load keep operate as normal and protected that load is soft, hardware is not damaged.
The ups power system is made up of five parts: power supply input circuit, the rectifier (REC) that carries out the AC/DC conversion, the inverter (INV) that carries out the DC/AC conversion, inversion and bypass output switching circuit and energy storage batteries such as main road, bypass, battery.The voltage stabilizing function of its system is normally finished by rectifier, rectifying device adopts controllable silicon or high-frequency switching rectifier, itself has the function that to control output amplitude according to the variation of dispatch from foreign news agency, thereby when dispatch from foreign news agency changes (this variation should be satisfied system requirements), the commutating voltage that output amplitude is constant substantially.Purification function is finished by energy-storage battery, because rectifier disturbs and can not eliminate transient pulse, still there is disturbing pulse in the voltage after the rectification.Energy-storage battery resembles concerning rectifier and has connect a bulk container capacitor except the function that can store the straight energy of direct current, and the size of its equivalent electric capacity is directly proportional with the energy-storage battery amount of capacity.Because the voltage at electric capacity two ends can not suddenly change, and has namely utilized the smoothness properties of capacitor paired pulses to eliminate impulse disturbances, has played purification function, also claim the shielding to disturbing.The stable of frequency then finished by converter, and frequency stability depends on the degree of stability of the frequency of oscillation of converter.Regular job and maintenance for making things convenient for the ups power system have designed the system works switch, the auto by pass switch after the main frame self check fault, switch controls such as maintenance by-pass switch.When line voltage was working properly, powering load charged to energy-storage battery simultaneously; When burst had a power failure, ups power was started working, and by the required power supply of energy-storage battery supply load, keeps normal production.
Because all electronic equipments all will produce heat in the course of the work, these heats must be discharged to device external, otherwise the accumulation of heat will cause the equipment operation troubles.For this large power energy storage power-supply device of UPS, its heat that produces when work can not be despised especially, at this moment, selects suitable ventilation or cooling system to become one of UPS equipment key of success decisive factor.
Select suitable ventilation or cooling system, at first need to know the quantity of heat production of equipment.The total caloric value of system is to be drawn by all heating equipment additions.Because UPS delivers to output with power from input, be distinguishing when calculating the heat dissipation capacity of UPS and during other-end equipment therefore.UPS is operated under the different patterns, and the heat of its generation also is different.In most running times of UPS, be operated under the normal state, namely AC power supplies is offered protected equipment, at this moment the UPS operational efficiency can reach 80% to 98%.Therefore, the idle work of UPS (or claiming power loss) can be between 2% to 20%, and this part ac input power can change into heat.The idle work that dissimilar UPS produces is by its design circuit structures shape, and should do corresponding approximate estimation and handle this moment.
Select according to environment for use, present universal UPS can be divided into technical grade UPS and business level UPS, and technical grade UPS is adapted to the more abominable place of environment, and the environment requirement of business level UPS is than higher.Just at present, universal UPS, the heat that produces in its course of work all carries out the exchange of heat by the circulation of equipment inner air and outer air, and this is for technical grade UPS and business level UPS, and common air-cooled equipment can be dealt with problems.But for this occasion that application circumstances and especial equipment requirements are arranged in colliery, universal UPS can't meet this requirement.
In view of complex environment under the colliery, the power-supply device that use in the colliery need adopt the flameproof enclosure protection that meets the safety of coal mines standard, and entire equipment is in the airtight fully flameproof cabinet.Lost the possibility of air exchange circulation, the ventilation cooling system that universal UPS is commonly used can not use, solves the thermal accumlation problem that produces in the UPS equipment course of work and need find new suitable solution route.
