| Why can not add Santak UPS power leakage protection |
| Time：2017-03-01 Source： Views：6003 |
Santak UPS power supply can not add leakage protection:
Santak UPS 1-3KVA power input is not recommended by the leakage switch rate without the best rate but for the input of the UPS 6K 20KVA is not connected leakage current leakage protection rate to a maximum of 5% input rate as 6KVA full load current 40A, so the leakage current for 2A. is not required to rate can also don't pick for the output of the leakage switch. Pay attention to the input side leakage rate given by Santak 1KVA UPS does not exceed 3.5 ma. This is a good UPS. rate under normal circumstances so a side leakage current protection of not less than 3.5 ma. The previous UPS cannot be installed leakage protection device is a weakness of the UPS industry, is still not a manufacturer can be solved, popular to say UPS is itself a leakage device, because when UPS online work should be filtered to the rectifier, voltage when some clutter, small current will release through the bottom line this will cause misoperation off leakage protector. The installation of leakage protection device in front of the UPS. UPS must not be general in order to eliminate the common mode interference, L N line has to filter circuit, UPS filter circuit, due to the effect of capacitance on the PE, very easy to cause the current L N line is not equal generally, the current leakage protection settings for 60MA, larger 300MA, is very easy to cause the error protection of leakage protection. Therefore, the general UPS is not installed in front of the leakage protector of the body is not so UPS With leakage protection.
The output end of the UPS install leakage protection old tripping rate what is the problem of how to solve the occlusion rate
The Santak UPS provides only a server with Load Tripping and switch power supply: the answer is without occlusion rate Load Tripping rate is ups if insufficient power or load short circuit, UPS input front-end add leakage protection. The output rate of UPS power distribution cabinet can be configured leakage protection device or leakage protector. Inverter and UPS similar input can not be connected to the leakage protection switch. The same filter leakage rate. The method of installing the isolation transformer in front of UPS. With the isolation transformer UPS power down rate start rate is no longer in the case of UPS occlusion in UPS FireWire, zero line and ground anti surge and wave interference Technology Co. It is because of the anti harmonic rate surge circuit is connected with a line from the end to the ground rather than the rate rate rate of the end line capacitors or other components rate rate resulting in leakage current rate which may cause leakage protection switch action.
Shenzhen Santak UPS power leakage protection switch the action principle of Shenzhen Santak UPS leakage protection switch is a core rate in group two had a rate of input current winding and an output winding current rate when no leakage rate when the input current and output current equal rate on the core flux vector and two zero rate will not be in the third winding induction voltage or third winding rate will form occlusion by amplifying the induction voltage to drive the actuator rate to switch trip. Santak UPS front power leakage protection switch rate while UPS power supply without leakage rate due to harmonic flux vector in the core and the formation of iron core and magnetic hysteresis cannot be zero rate and appeared similar leakage rate. The earth leakage protection device of frequent trip. So we try not to rate on Santak UPS AC input rate to avoid the use of circuit breaker switch with leakage protection rate rate. UPS power is the uninterruptible power supply rate it is the existence of a AC - DC and DC - AC rate and a process rate electricity rate to the rectifier battery charging rate while providing DC voltage to the inverter work rate when mains failure rate directly from the battery to provide DC voltage to the inverter rate rate rate DC the work rate standard AC output. The causes of these problems involve three aspects of UPS uninterruptible power supply quality, UPS uninterruptible power supply installation quality, user quality. This requires the use of ups to meet the requirements of the uninterruptible power supply and the correct installation of UPS uninterruptible power supply. In the user's quality is mainly determined by the user's specific use of environmental quality, power quality and daily maintenance quality. When the UPS battery failure, should find out the reason. Distinguish the source of the fault is the load or UPS power supply system; host or battery. Although the UPS host fault self-test function, but it is not the opposite point, although the replacement of parts is very convenient, but to repair the fault point, still need to do a lot of analysis, testing. UPS with battery pack built-in and external two, built-in battery, UPS is relatively easy to use, there is no problem with the UPS host and battery connection. The external battery, UPS must pay attention to the host and battery connection problems. First of all, the battery must be positive and negative even good, and check the voltage of the battery pack, the voltage and the size of the UPS host requirements in order to calculate the correct connection. Second, open the UPS host, and measure the charging power of the UPS host
Pressure, voltage value is correct. Uninterruptible power supply for long idle UPS, before re put into use, it is better to let the UPS float on the battery for later use 10-12h charging circuit inside the machine. For the backup UPS users, if UPS long-term work in the backup work state, that every month, let UPS in the operating state of at least 2 3min rate, in order to activate the battery.
Breaker rate Sendon UPS power supply load circuit can not be installed with leakage protection UPS in order to eliminate the common mode interference rate of between zero and FireWire and zero rate of filter capacitor and fire are current rate may cause zero line current, so that the rate ranging from tripping of the circuit breaker with leakage. Therefore, the Santak UPS power supply and load circuit can not be loaded
