Abstract

The utility model provides a simple and convenient battery undervoltage alarming device. A battery and an electric bell are respectively connected with wiring terminals of a control cabinet through conducting wires. A resistor R1 and a resistor R2 are connected in series, and then connected to the wiring terminals of the control cabinet through conducting wires. A multi-function digital readout is connected with the wiring terminal of the control cabinet. The resistors R1 and R2 are set according to the conditions that R2 is equal to 22R1 and R1 is greater than 5 times of the internal resistance of the multi-function digital readout. The resistors R1 and R2 are connected in series, and then are carried with voltage division, and both ends of the resistor R1 have 0-10V direct current voltage signals. The multi-function digital readout can obtain the 0-10V direct current voltage signal. The multi-function digital readout displays the 0-250V voltage. When the voltage is lower than 200V, the multi-function digital readout closes one pair of nodes and drives the electric bell on the far end to generate sound alarm. The utility model has the advantages of simple structure, convenient installation, low cost, sound alarming and good effect.

Description

A kind of direct current cabinet battery pack undervoltage warning device
Technical field
The utility model relates to a kind of direct current cabinet battery pack undervoltage warning device, belongs to electrical control protection field.
Background technology
Must not allow the staff find in advance when battery pack provides reliable direct supply under the situations such as the AC power failure of direct current cabinet, rectification circuit fault, battery pack faults itself and in time handle.Addressing this problem the main staff's walkaround inspection that leans at present in time finds to handle.Some advanced persons' complete direct current cabinet equipment, the literal warning message is provided on its general controller display screen or realizes the screen warning to the computer terminal with network communication, its local warning still relies on staff's walkaround inspection, it is far reported to the police based on network, the cost height, small to some, automaticity is not high, the generating plant and the transformer and distribution power station that do not have full-time duty personnel again are uneconomical.
Summary of the invention
The purpose of this utility model just provides a kind of simple and easy battery pack under-voltage warning device.
The technical solution of the utility model is: battery pack is connected with the terminals of switch board by lead respectively with electric bell, resistance R 1 and R2 series connection back are connected on the connection terminal of switch board by lead, the multifunctional digital table is connected with the connection terminal of switch board, resistance R 1 and R2 press R2=22R1 and R1>5 times two condition setting of multifunctional digital table internal resistance, R1 and R2 series connection back dividing potential drop also has the d. c. voltage signal of 0-10V at the R1 two ends, the multifunctional digital table obtains the d. c. voltage signal of 0-10V, the multifunctional digital table shows 0-250V voltage, and drives the electric bell that is arranged on the distant place warning of sounding by the closed a pair of node of multifunctional digital table when being lower than 200V.
The effect that the utility model is useful is: warning device is simple in structure, and is easy for installation, and cost is low, and audible alarm is effective.
