Abstract
The utility model relates to a power supply module which can reduce overhauling workloads, reduce maintenance cost and improve the operating reliability and is used for fault indicator. The power supply module is characterized by comprising a current transformer CT into which 10KV circuit induction alternating current is inputted and a CT power taking power supply for converting the alternating current into direct current, wherein the output end of the CT power taking power supply is connected with a DC/DC voltage-stabilized power supply for supplying power to the fault indicator and is connected with a charge-discharge module by a power supply control switch; the input end of the power supply control switch is also connected with a switch power supply into which 220V is accessed; and charge-discharge conversion and the switching of the switch power supply can be realized by the power supply control switch.
Description
Technical field
The utility model relates to a kind of fault detector power module.
Background technology
The fault detector used in traditional electric power system is generally built-in disposable lithium electricity, or the rechargeable battery of low capacity, this fault detector power consumption is little, and general lithium electricity just can meet its demand, because it does not possess communication function, after fault, can't determine fast position.In order to address this problem, the novel fault indicating device with communication module has appearred, because there is communication module, so power consumption is relatively much larger, with the power supply of disposable lithium electricity, do not reach the power consumption requirement; With rechargeable battery powered, the life-span does not reach instructions for use; Cause fault rear section fault detector to work, can't determine fast position.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of maintenance workload that reduces, and reduces maintenance cost, improves the fault detector power module of fault detector functional reliability.
Technical solution of the present utility model is:
A kind of fault detector power module, its special character is: it has a current transformer that is input as 10KV line influence alternating current, is used for alternating current is become to galvanic CT power taking power supply, described CT power taking power output end is connected with for the DC/DC stabilized voltage power supply to the fault detector power supply, described CT power taking power output end is connected to charge-discharge modules by power control switch, also be connected to the Switching Power Supply of 220V access at the power control switch input, by power control switch, can realize discharging and recharging conversion and Switching Power Supply switching.
Described charge-discharge modules has 5V, two groups of outputs of 24V.
Replace the conventional batteries power supply by current transformer in the 10KV power taking, power supply is input as the alternating current of 10KV circuit inductance, adopt single CT power supply, give the power supply of DC/DC stabilized voltage power supply and through power control switch, charge-discharge modules is charged after CT power taking power supply is converted to the 5V direct current by AC signal.The Switching Power Supply of access 220V is as stand-by power supply, and during access, through power control switch switching access, charge-discharge modules can be stablized charging repeatedly, and maintenance workload greatly reduces, and reduces maintenance cost.After 10KV circuit outage, by charge-discharge modules through power control switch to the power supply of DC/DC stabilized voltage power supply, fault detector is worked on, can uploading data within 10 minutes, thereby improve the fault detector functional reliability.
The accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
As shown in the figure, this fault detector power module, it has one to be input as current transformer 1 that 10KV line influence alternating current and no-load voltage ratio are 500:1, to be used for alternating current is become to the galvanic CT power taking of 5V power supply 2, described CT power taking power supply 2 outputs are connected with for the DC/DC stabilized voltage power supply 3 to the fault detector power supply, DC/DC stabilized voltage power supply 3 is for powering to fault detector, described CT power taking power supply 2 outputs are connected to charge-discharge modules 5 by power control switch 4, and described charge-discharge modules 5 has 5V, two groups of outputs of 24V 501,502.Also be connected to the Switching Power Supply as stand-by power supply 6 of 220V access at power control switch 4 inputs, by power control switch 4, realize discharging and recharging conversion and Switching Power Supply switching.
