Abstract
The utility model relates to detection equipment of a UPS device battery state. The detection equipment is connected with a UPS device. The equipment comprises a voltage detection circuit and a load which are connected with the UPS device. The voltage detection circuit is used for detecting UPS device zero load state first voltage and judging whether the first voltage is lower than rated voltage or not, if not, output end voltage is detected and displayed when the UPS device output end is connected with the load, and if so, a UPS device damage alarm signal is sent out. By using the voltage detection circuit, when the system power supply is normal, when a working condition permits, the connection of an alternating current power supply side of the UPS is disconnected such that the system is in a power off state, at the same time, a UPS output end is connected with a rated load resistor, the change of end voltage of a storage battery under zero load and rated load states is measured, if the change is larger than a set limit, the aging of the battery is determined, and the replacement of the battery is prompted. A judgment is made through comparing the change of the storage battery end voltage before and after the connection of the rated load, and the accuracy is very high.
Description
Technical field
The utility model belongs to power domain, relates in particular to a kind of checkout equipment of UPS device battery state.
Background technology
Usually need to adopt the UPS(backup power in the small-sized wind power generator) as the emergency power supply after the mains power failure, because the pick-up unit more complicated of the battery status of battery pack, among the small-sized UPS often with its omission, but in wind generator, for the demand to security, often need system to know the battery status of its back-up source.Traditional method is to measure battery terminal voltage and be sent to master cpu as the judging basis of battery status, but because internal resistance changes the uncertainty that presents in the accumulator ageing process, this kind method causes relatively large deviation to the judge of battery status, makes the security of system assessment deviation occur.
Summary of the invention
The utility model provides a kind of with low cost for small-sized wind power generator in view of the technological deficiency that prior art in use exists, the checkout equipment of simply constructed UPS device battery state.
For achieving the above object, the technical solution adopted in the utility model is: a kind of checkout equipment of UPS device battery state, connect the UPS device, and it is characterized in that: comprise the voltage detecting loop and the load that are connected with described UPS device;
Described voltage detecting loop is for detection of described UPS device light condition the first voltage and judge whether described the first voltage is lower than rated voltage, otherwise detection also shows output end voltage when described UPS device output terminal connects load condition, is then to send UPS device faiture alarm signal.
The first preferred version of the present utility model is also to comprise the civil power that is connected with described UPS device by power supply relay.
Technical advantage of the present utility model is: by the voltage detecting loop, when system power supply is normal, when operating mode allows, the alternating current source that disconnects UPS connects, and makes it be in the power cut-off state, connects nominal load resistance at the UPS output terminal simultaneously, measure the variable quantity of the terminal voltage of the accumulator under zero load and the rated load condition, if greater than setting the limit, it is aging then to be judged to be accumulator, prompting is changed.Variation by the accumulator voltage before and after the access of comparing nominal load judges to have very high accuracy.
Description of drawings
Fig. 1 is the checkout equipment module diagram of present embodiment module UPS device battery state.
Embodiment
Embodiment 1.
With reference to figure 1, a kind of checkout equipment of UPS device battery state comprises the power supply relay that is connected with the UPS device, and power supply relay connects the civil power of 220V; Also comprise the voltage detecting loop that is connected with the UPS device; Also comprise the load detecting relay that is connected with the UPS device, described load detecting relay is connected with load.The checkout equipment of UPS device battery state when externally power supply is normal because the intervention of charge circuit can't be made accurately the ageing state of accumulator in the UPS device judges, so, in the needs test battery health, deenergization relay at first, then record the terminal voltage of accumulator in the UPS device by the voltage detecting loop, be labeled as V0, if V0 then reports an error: accumulator failure immediately less than accumulator specification voltage Vb.If V0 is greater than Vb, then connect load-relay, to specified load output rated current, record the accumulator output end magnitude of voltage after 30 seconds, be labeled as V1, if V1＜n*Vb is (n:0.75-0.85, by the concrete specification definition of accumulator), think that then accumulator is aging, although can satisfy reluctantly current use, needed to change.
Protection scope of the present invention is not limited to the scope that embodiment explains, and all belong in protection scope of the present invention based on the change of inventive concept.
Claims (2)
1. the checkout equipment of a UPS device battery state connects the UPS device, it is characterized in that: comprise the voltage detecting loop and the load that are connected with described UPS device;
