Abstract
The utility model relates to an active phased array antenna protection device imports and exports the flow and calculates its flow poor through detecting active phased array antenna coolant liquid, poor and then judge whether normal the work in liquid cooling source is, cuts off the power supply to active phased array antenna when reaching the threshold value according to the flow, and the device has avoided the antenna to work under the unusual circumstances of cooling system, accessible time finds coolant liquid circulation trouble, protects the antenna equipment, reduction economic loss.
Description
Technical field
The present invention relates to a kind of antenna protecting equipment, particularly to a kind of active phase array antenna protection device.
Background technology
Active phase array antenna has the advantage such as working band width, frequency agility speed is fast, minor level is low, multi-beam scanning, multiple target tracking, is the 4 most important radio frequency sensors of generation opportunity of combat.Antenna is mainly made up of T/R assembly, phase shifter, ripple control device, power division network and cooling cavities etc..
Pressure restriction due to microwave active device, the working power of active phase array antenna is DC low-voltage, requirement for satisfied war skill index, T/R component count in antenna is numerous, generally more than 2000, thus causing supply current to be up to 400A (only receiving state), inner antenna caloric value is huge, coolant must be used to be circulated cooling, to keep the normal working temperature of T/R assembly.If coolant cycle interruption and DC source continued power, the T/R assembly of antenna will burn because of high temperature in 3-5 minute, will result in the economic loss of tens million of unit.
Summary of the invention
There is provided a kind of for the problems referred to above this utility model and can find coolant circulatory troubles, the active phase array antenna protection device of reduction economic loss in time.
For solving the problems referred to above; the technical scheme that this utility model is taked is: a kind of active phase array antenna protection device; including active phase array antenna, for the low-voltage dc power supply of active phase array antenna offer working power and through the liquid low-temperature receiver that the cold pipeline of liquid is active phase array antenna offer coolant, also include detector unit, control unit and alarm unit；
Described detector unit includes the inlet flow rate being respectively used to detect active phase array antenna coolant and rate of discharge and the flow value of detection passes to the first delicate flow meter and the second delicate flow meter of control unit；
The antenna power disjunction that the liquid low-temperature receiver power supply disjunction that described control unit includes microprocessor and interface circuit, be connected between microprocessor and liquid low-temperature receiver controls device, be connected between microprocessor and low-voltage dc power supply controls device；
Described alarm unit includes the acoustic-optic alarm being controlled by microprocessor.
The inlet flow rate detected and rate of discharge are transferred to control unit by detector unit, and flow value is processed and compares with arranging value by control unit, decide whether to start acoustic-optic alarm and the need of disconnecting liquid low-temperature receiver and antenna power after judging.Described liquid low-temperature receiver power supply disjunction controls device all can use, with antenna power disjunction control device, the relay being controlled by microprocessor, is controlled the break-make of liquid low-temperature receiver and low-voltage dc power supply by relay.
The inlet flow rate detected, rate of discharge are transferred to microprocessor by the first described delicate flow meter and the second delicate flow meter.Microprocessor calculates imports and exports difference in flow, and judge this difference in flow whether beyond setting value, if beyond; would first disconnect antenna power and be then turned off liquid low-temperature receiver power supply, and control acoustic-optic alarm and report to the police.
Described liquid low-temperature receiver power supply disjunction controls device and is connected to three-phase alternating-current supply with antenna power disjunction control device.
The technique effect of the present invention: the technical program is imported and exported flow by detection active phase array antenna coolant and calculated its difference in flow; according to difference in flow and then judge that the work of liquid low-temperature receiver is the most normal; when a threshold is reached active phase array antenna is carried out power-off; the device avoids antenna to work in the case of cooling system is abnormal; coolant circulatory troubles can be found in time, protect antenna equipment, reduce economic loss.

Fig. 1 is connection diagram of the present utility model.
Detailed description of the invention
A kind of active phase array antenna protection device; including active phase array antenna, for active phase array antenna provide working power low-voltage dc power supply and through the cold pipeline of liquid be active phase array antenna provide coolant liquid low-temperature receiver; the antenna power disjunction that the liquid low-temperature receiver power supply disjunction also include microprocessor and interface circuit, being connected between microprocessor and liquid low-temperature receiver controls device, be connected between microprocessor and low-voltage dc power supply controls device, and described liquid low-temperature receiver power supply disjunction controls device and controls device with antenna power disjunction and be connected to three-phase alternating-current supply.
Additionally, microprocessor is also associated with acoustic-optic alarm.The inlet flow rate and rate of discharge the first delicate flow meter and the second delicate flow meter that the flow value of detection is passed to microprocessor being respectively used to detect active phase array antenna coolant it is provided with in liquid low-temperature receiver and source phased array antenna.
