By adopting the laboratory uninterrupted power supply system of the invention, the accuracy of the test data can be ensured when there is an emergency, and the test cost can be reduced.
Description
Technical field
The present invention relates to electric power system technical field, particularly a kind of laboratory uninterruptible power system.
Background technology
The laboratory electric power system in past, usual employing is powered by the mode of a Power supply, the advantage of this supply power mode is exactly that system is simple and clear, the power supply unit needed is few, investment is in advance low, but shortcoming is also very outstanding, is exactly that externally fed is once interruption or this transformer break down, the power failure of whole supply load will be caused, the carrying out of the cycle that affects longer test.
Through long-term practice, laboratory recognizes that single power supply mode exists wretched insufficiency, after particularly supply load being divided into Three Estate, single power supply mode can not adapt to present needs, therefore has developed new supply power mode---dual transformer supply power mode.This supply power mode is that supply load is divided into two parts, is powered respectively, form respective electric power system by two transformers.In addition, between two transformers, increase a network interconnecting circuit, two transformers are coupled together.This network interconnecting circuit is when two transformer normal power supplies, be in gate-dividing state, every platform transformer powers to respective be with load, non-interference, but when wherein a transformer is stopped power supply because of certain reason, now by combined floodgate network interconnecting circuit, two electric power systems are united two into one, powered by the transformer normally worked, ensure that the continuity of power supply.The advantage of this supply power mode is that power supply is continuous, and load will be caused to have a power failure because of supply line or transformer fault, shortcoming is that comparatively single power supply is high in early investment.
The mode that above-mentioned dual transformer is powered also has many deficiencies, such as two two transformers are all in running order at ordinary times, affect transformer useful life and increase reactive loss, need two cover reactive power compensation devices, in addition, when two-way power supply is stopped power supply all for some reason simultaneously, important load in system, the pilot project that such as can not have a power failure, fire fighting burthen etc., be lost power supply, therefore must improve above-mentioned supply power mode.
Summary of the invention
For solving the problem, the object of this invention is to provide a kind of power supply more reliable, both having ensured that the test of the longest test period was not interrupted, in turn ensure that the accuracy detecting data, and reduce a kind of laboratory uninterruptible power system of testing cost.
A kind of laboratory uninterruptible power system, mainly comprises primary transformer, spare transformer, first order dual power supply automatic switching device, reactive power compensation device, general distribution load, house generator, second level dual power supply automatic switching device, important supply load.This electric power system is powered by primary transformer, spare transformer, and primary transformer, spare transformer can be for subsequent use each other, and wherein only have a transformer in work, another is for subsequent use.First order dual power supply automatic switching device is connected to primary transformer and spare transformer rear end.Be equipped with a set of reactive power compensation device in electric power system, be placed in first order dual power supply automatic switching device rear end.General distribution load is placed between reactive power compensation device and second level dual power supply automatic switching device; Important supply load is placed in dual power supply automatic switching device rear end, the second level; For avoiding primary transformer, spare transformer has a power failure all for some reason, important supply load is caused to lose the situation of power supply, add house generator in systems in which, by generator enabling signal and the automatic switching mode of second level dual power supply automatic switching device, give the important supply load continued power that can not have a power failure.
Laboratory of the present invention uninterruptible power system, when being in an emergency, not only can ensure that the test of the longest test period is not interrupted, and can also ensure the accuracy detecting data, and reduce testing cost.In addition when there is such as fire, effectively can ensure fire power, reducing casualties, reduce property loss.

Fig. 1 is the structured flowchart of laboratory of the present invention uninterruptible power system;
Fig. 2 is the structural representation of laboratory of the present invention uninterruptible power system.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
A kind of laboratory uninterruptible power system as shown in Figure 1 and Figure 2, mainly comprises primary transformer 1, spare transformer 2, first order dual power supply automatic switching device 3, reactive power compensation device 4, general distribution load 5, house generator 6, second level dual power supply automatic switching device 7, important supply load 8.This electric power system is powered by primary transformer 1, spare transformer 2, and primary transformer 1, spare transformer 2 can be for subsequent use each other, and wherein only have a transformer in work, another is for subsequent use.First order dual power supply automatic switching device 3 is connected to primary transformer 1 and spare transformer 2 rear end.Be equipped with a set of reactive power compensation device 4 in electric power system, be placed in first order dual power supply automatic switching device 3 rear end.General distribution load 5 is placed between reactive power compensation device 4 and second level dual power supply automatic switching device 7; Important supply load 8 is placed in second level dual power supply automatic switching device 7 rear end; For avoiding primary transformer 1, spare transformer 2 has a power failure all for some reason, important supply load 8 is caused to lose the situation of power supply, add house generator 6 in systems in which, by generator enabling signal and the automatic switching mode of second level dual power supply automatic switching device 7, give the important supply load continued power that can not have a power failure.
Laboratory of the present invention uninterruptible power system, when the situation that the primary transformer 1 of appearance, spare transformer 2 all can not be powered, enabled instruction is sent to house generator 6 after detecting dead electricity signal by second level dual power supply automatic switching device 7, automatic startup house generator 6, then second level dual power supply automatic switching device 7 automatically switches to generator powered circuit, continue to power to important supply load 8, ensure that the continuity that important supply load 8 is powered.
Laboratory of the present invention uninterruptible power system, when being in an emergency, has ensured that the test of the longest test period is not interrupted, and ensure that the accuracy detecting data, and reduces testing cost.In addition when there is such as fire, effectively can ensure fire power, reducing casualties, reduce property loss.
