Description
Technical field
The utility model relates to the power technology field, particularly relates to the Redundancy Design of on-line monitoring device for transmission line supply unit.
Background technology
The transmission line malfunction monitoring terminal is installed on the lead high potential, and the electromagnetic environment of work and atmospheric environment are abominable and complicated, also is difficult to safeguard simultaneously.Power module highly reliable, high stability is most important, must take the relevant redundancy design.
The power supply the principle of transmission line induction energy fetching supply unit is to utilize electromagnetic induction principle, can respond to alternating voltage from high voltage bus or circuit by coil by getting, and is high-pressure side electronic circuit load power supply then after over commutation, filtering, voltage stabilizing.
The working method of current power transmission line influence energy taking device mainly contains following three kinds of modes: first kind is at induction coil output designing voltage regulator circuit, and the electric energy of sensing is directly offered power consumption equipment.This working method is not owing to there is a standby energy-storage travelling wave tube, and when transmission line breaks down when causing power failure, system just can not work.Second kind is that induction power taking coil directly charges a battery, again by the storage battery powering load.This working method is more suitable for energy consumption greatly and the power consumption equipment that power quality is had relatively high expectations.But because storage battery exists the life-span short, it is bigger that performance is influenced by adverse circumstances, and the supply unit of this working method exists functional reliability poor, the shortcoming that the life-span is short.The third is as standby redundant power with lithium battery, little or cause electricity shortage when having a power failure when the line load electric current, use the reserve battery powering load this moment, with respect to preceding dual mode, the third method is more commonly used, but when the induction energy fetching power supply change-over device damages because thunderbolt waits the line fault that causes, just cause system's permanent fault when then the energy content of battery exhausts.
Summary of the invention
Based on this, being necessary the technical problem that does not possess UPS characteristic and highly redundant that exists in the transmission line induction energy fetching supply unit that adopts prior art provides a kind of transmission line induction energy fetching supply unit with highly redundant characteristic.
A kind of transmission line induction energy fetching supply unit with highly redundant characteristic, supply unit comprises the induction energy fetching coil, main power board, the stand-by power supply plate, high power lithium battery, the power adjustments control unit, voltage feedback unit, the power supply switch control unit, the output that is connected with load, induction energy fetching coil while and main power board, the stand-by power supply plate connects, main power board, stand-by power supply plate and high power lithium battery connect the power adjustments control unit simultaneously, the power adjustments control unit is connected with the power supply switch control unit, and output is connected with the power supply switch control unit by voltage feedback unit.Thereby which power supply power supply the power supply method for handover control determines by for judging according to the load voltage feedback whether the passage power supply breaks down for the power supply method for handover control.
Above-mentioned transmission line induction energy fetching supply unit with highly redundant characteristic adopts the induction energy fetching power supply highly redundant mode of main power supply plate and lithium battery, thereby judges according to the load voltage feedback which power supply power supply whether the passage power supply break down decision by.
Compared with prior art, the advantage that a kind of transmission line induction energy fetching supply unit with highly redundant characteristic has is: the one, possess UPS (English name is Uninterruptible Power System) characteristic, come interim for fault moment, can satisfy the power reguirements of high-power on-line monitoring device for transmission line system, can not cause the system loss fault message because of electricity shortage; The 2nd, highly redundant when transmission line waits the line fault that causes because of thunderbolt, can not occur causing supply unit to damage owing to hitting in the row ripple in the circuit, thereby cause the on-line monitoring device for transmission line system to produce the situation of permanent damage because of power issue.

Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Be illustrated in figure 1 as the structural representation of an embodiment of a kind of transmission line induction energy fetching supply unit with highly redundant characteristic of the utility model.The utility model comprises induction energy fetching coil, main power board, stand-by power supply plate, high power lithium battery, power adjustments control unit, voltage feedback unit, power supply switch control unit, the output that is connected with load; The induction energy fetching coil is connected with main power board, stand-by power supply plate simultaneously, main power board, stand-by power supply plate and high power lithium battery connect the power adjustments control unit simultaneously, the power adjustments control unit is connected with the power supply switch control unit, and output is connected with the power supply switch control unit by voltage feedback unit.
Supply unit is the load power supply by main power board at first, and the backup battery plate is cut off, and when main power board broke down, then switching to the backup battery plate was the load power supply, and main power board is cut off.Whether main power supply plate and lithium battery connect the power adjustments control unit simultaneously, can big or small the reaching of coil output voltage control power panel AC-input voltage by power panel lithium battery be charged according to getting by the power adjustments control unit.The power adjustments control unit is connected with the power supply switch control unit again, selects a wherein road direction power devices by commutation circuit, and rest channels is cut off, and is standby mode.The power supply switching controls directly links to each other with load, load is connected with the power supply switching controls through the voltage feedback, then which road means of power is the power supply switching controls judge by according to the feedback voltage of load, when the unit to power devices breaks down, commutation circuit is moved immediately, make another unit to power devices, simultaneously the output of disengagement failure unit.When circuit has a power failure because of failure and other reasons, the main power supply plate can't be powered to load this moment, then by diverter switch lithium battery be powered to load.
Be illustrated in figure 2 as induction energy fetching main circuit topological structure schematic diagram among the embodiment of a kind of transmission line induction energy fetching supply unit with highly redundant characteristic of the utility model.
The main circuit topology of main power supply plate adopts full-bridge rectification, is made up of AC-input voltage, front end surge protection, full bridge rectifier, overvoltage protection, DC/DC conversion and DC power supply output.
