Abstract
The utility model relates to the alarm technology field, and discloses a fault alarm of a power distribution cabinet power control system. The fault alarm of the power distribution cabinet power control system comprises an electric storage device which is used to store charge and is connected with a power supply of a power distribution cabinet control system via a unidirectional charging circuit, and the power supply of the power distribution cabinet control system is connected with the electric storage device via an alarm circuit, and the alarm circuit is formed by connecting a trigger switch circuit and an acousto-optic alarm. When the fault alarm of the power distribution cabinet power control system of the utility model works and when a power supply fault of the power distribution cabinet control system occurs, the power supply does not need to be supplied, so that an alarm signal can be sent out normally.
Description
Technical field
The utility model relates to the alarm technique field, relates in particular to a kind of power distribution cabinet power control system fault alarm.
Background technology
At present, the power distribution cabinet power supply is the important component part of power supply control system, and whether it is directly connected to whole power distribution control system can steady operation.If because the control system cisco unity malfunction that power fail causes after power supply breaks down, outwards sends indicating fault so at once, the time waste of fixing a breakdown with minimizing is the important measures that reduce to lose.And general power fail warning circuit all needs an extra power supply to provide power supply to it, to guarantee can normally sending alerting signal after breaking down.Can power supply work,
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provides a kind of power distribution cabinet power control system fault alarm, can at the control system power supply alarm that breaks down, solve the technical matters that existing warning device needs extra power supply.
For achieving the above object, following technical scheme is adopted in the invention:
A kind of power distribution cabinet power control system fault alarm has an electrical storage device that stores electric charge and be connected with power distribution cabinet control system power supply by unidirectional charging circuit, and power distribution cabinet control system power supply is connected with electrical storage device by warning circuit; Described warning circuit is connected to form by trigger switch circuit and audible-visual annunciator.
Owing to adopting technical scheme as above, the invention has following superiority:
A kind of power distribution cabinet power control system fault alarm adopts the electrical storage device that stores electric charge, when power distribution cabinet control system power supply breaks down, need not to provide power supply, just can normally send alerting signal.
Description of drawings
Fig. 1 is the block scheme of power distribution cabinet power control system fault alarm;
Embodiment
As shown in Figure 1, a kind of power distribution cabinet power control system fault alarm, have an electrical storage device C who stores electric charge and be connected with power distribution cabinet control system power supply V by unidirectional charging circuit Z, and power distribution cabinet control system power supply V is connected with electrical storage device C by warning circuit B; Described warning circuit B is connected to form by trigger switch circuit K and audible-visual annunciator S.Described electrical storage device C is for storing the electric capacity of electric charge.
During use, power distribution cabinet control system power supply charges to electrical storage device by unidirectional charging circuit under normal circumstances, electrical storage device stores electric charge, when power distribution cabinet control system power generation fault, direct supply becomes 0V, simultaneously, the warning circuit trigger switch circuit turn-on that is connected with power distribution cabinet control system power supply, audible-visual annunciator is connected with electrical storage device, sends sound and light alarm, prompting power distribution cabinet control system power supply breaks down.
Claims (1)
