Description
Technical field
The utility model relates to switch, particularly a kind of static switch that is applied on the uninterrupted power supply.
Background technology
Uninterrupted power supply (UPS, Uninterruptible Power Supply) can ensure that computer system works on a period of time so that the user can promptly deposit after having a power failure, make that the user is unlikely to influence work or obliterated data because of power failure.It mainly plays two effects in computer systems and networks is used: the one, and emergent the use prevents sudden power and influences operate as normal, causes damage to computer; The 2nd, eliminate " power pollutions " such as surge on the civil power, instant high-voltage, moment low-voltage, electric wire noise and frequency shift (FS)s, improve power quality, for computer system provides high-quality power supply.
From basic application principle, UPS is a kind of energy storage device that contains, and is main element with the inverter, the power protective equipment of voltage stabilization and frequency stabilization output.It mainly is made up of several parts such as rectifier, storage battery, inverter and static switches.Rectifier becomes alternating current into direct current, and supply load after filtering is perhaps supplied with inverter; Go back accumulators simultaneously charging voltage is provided.Storage battery at civil power just often converts electric energy to chemical energy and is stored in inside battery, when municipal power failure, converts chemical energy to electric energy and offers inverter or load.Inverter is made up of inverter bridge, control logic and filter circuit, is used for direct current is converted into alternating current.Static switch is a kind of noncontacting switch, is a kind of alternating-current switch of forming with two thyristor reverse parallel connections, and its closed and disconnected is controlled by logic controller.Be divided into conversion hysteria and and two kinds of types.The conversion hysteria switch is mainly used in the system of two-way power supply power supply, and its effect is to realize from one road automatic switchover to another road; And the type switch is mainly used in shunt chopper and civil power or many inverters.
At present, the thyristor of the static switch that industry has is welded on the pcb board, and this mode fuses pcb board and thyristor, but when electric current was big, circuit can be very complicated, is unfavorable for PCB layout.For this reason, industry has been taked another kind of mode, be exactly that thyristor is connected with power device by cable, the supply unit that has promptly adopted the static switch of the second way shown in Figure 1, it comprises the static switch 100 that is arranged on the bottom, is arranged on the inductance element 200 on the rear wall and external terminal 300 on the sidewall is set, and links to each other by cable (not shown) between static switch 100 and the external terminal 300.As shown in Figure 2, static switch 100 mainly comprises six thyristors 110, bar shaped copper bar 120, radiator 130, fastener 140 and dihedral copper bar 150.Thyristor 110 is arranged side by side, and the top of each thyristor is equipped with three wiring holes 111,112,113, the wiring hole 112 of adjacent two thyristors links to each other by bar shaped copper bar 120, all is connected with a dihedral copper bar 150 that links to each other with inductance element 200 on the wiring hole 113 of each thyristor.All be connected with the cable (not shown) that links to each other with external terminal 300 on bar shaped copper bar 120 and the wiring hole 111, have nine cables.
Yet, from the schematic layout figure of the static switch of the existing power supply shown in Fig. 3 as can be known, the cable 500 of drawing on the static switch 100 takes up space bigger, and because the crooked process radius of cable 500 is not enough, make the cable 500 contiguous inductance element 200 of touching easily, inductance element 200 is a heater element, and causes cable 500 temperature to rise; In addition, also be provided with pcb board 400 on the top of static switch 100, the leg of pcb board 400 might puncture the insulating barrier of cable 500, and causes cable 500 electric leakages.Therefore, the static switch of existing power supply exists comparatively serious potential safety hazard.
