Abstract
The utility model discloses an online measurement circuit structure for charging circuit breaking of a storage battery set. A micro control board is connected onto a signal collector U1, and the signal collector U1 is connected onto the direct current + (DC+) end of a charging board through a current-limiting resistor R and a diode D3. When in charging, after passing through an isolation transformer T, a rectifying circuit, the signal collector U1, the current-limiting resistor R and the diode D3, utility power enters a charging system to form a charging detecting circuit. The online measurement circuit structure is simple in circuit structure and reliable and stable in detecting results, not only can detect a status of the charging circuit breaking in heavy current charging, but also can detect a status of the charging circuit breaking of low current in floating charging state.
Description
Technical field
The utility model belongs to the line Measurement Technique field of battery charging circuit broken string, specifically relates to a kind of on-line measurement circuit structure of battery charging circuit broken string.
Background technology
The on-line measurement of battery charging circuit broken string is applied to contain the on-line detecting system of battery charging circuit burn out detection, as fire emergency centrally connected power source, fire fighting equipment emergency power pack, UPS etc.At present, the online detection of general battery charging circuit broken string is adopted by detecting loop current or voltage, specific as follows, adopt the loop current mode that detects, when charging current 0A, think broken string, this just requires also to want when charging current is very little under the battery pack floating charge situation and can detect, to current sample accuracy requirement height; When adopting the voltage detecting mode, behind the charging circuit broken string, determine whether broken string by the terminal voltage of measuring the charging output loop, the defective of this mode is to break behind battery float, terminal voltage is high slightly or constant substantially, so just is difficult to conclude whether charging circuit breaks, wrong report easily.
Summary of the invention
In order to overcome the deficiency that the existing method floating charge state of battery charging circuit broken string is difficult to conclude, the utility model provides a kind of on-line measurement circuit structure of battery charging circuit broken string, the situation of charging circuit broken string in the time of can measuring large current charge, the situation of charging circuit broken string when energy measurement goes out the little electric current of floating charge state again.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of on-line measurement circuit structure of battery charging circuit broken string, the micro-control plate is connected to signal picker U1, and signal picker U1 is connected to the DC+ end of charging panel again through current-limiting resistance R, diode D3; Civil power enters charging system formation charging detection line during charging behind isolating transformer T, rectification circuit, signal picker U1, current-limiting resistance R, diode D3.
The measuring method of above-mentioned on-line measurement circuit structure is:
A. when the micro-control plate detects charging circuit big electric current is arranged, show the charging circuit operate as normal;
B. when the micro-control plate detects charging circuit little electric current is arranged, do not charge by micro-control plate control charging system, the micro-control plate determines by the link B point voltage of detection signal collector U1 and micro-control plate whether charging circuit breaks, concrete grammar is: if the charging circuit operate as normal, civil power enters charging system and constitutes the charging detection line behind isolating transformer T, rectification circuit, signal picker U1, current-limiting resistance R, diode D3, signal picker U1 work, the B point is a low-voltage; If the charging circuit broken string, civil power can't enter charging system behind isolating transformer T, rectification circuit, signal picker U1, current-limiting resistance R, diode D3, and signal picker U1 does not work, and the B point is a high voltage.
The utility model circuit structure is simple, and measurement result is reliable and stable, the situation of charging circuit broken string in the time of can measuring large current charge, the situation of charging circuit broken string when energy measurement goes out the little electric current of floating charge state again.
