Description
Technical field
The monitoring field of wind power plant is the utility model is related to, specially a kind of novel fan theft-resistant link chain.
Background technology
Environmental protection, saving resource are just obtaining increasingly extensive attention, in order to reduce the consumption of fossil fuel, reduce greenhouse
The discharge of gas, the various new energy including wind energy are just obtaining increasingly extensive use, are to utilize wind using wind power generation
The important measures of energy.Control to blower fan needs to use theft-resistant link chain, and theft-resistant link chain is last pipe protection of blower fan, is one group of series connection
Normally closed connection circuit, theft-resistant link chain action can trigger emergency shutdown.But also there is complicated, prison for current theft-resistant link chain
The shortcomings of controlling not high real-time, monitored results poor intuition.
Utility model content
The defects of in order to overcome prior art, there is provided a kind of simple in construction, control is accurately controlled device, the utility model
Disclose a kind of novel fan theft-resistant link chain.
The utility model reaches goal of the invention by following technical solution：
A kind of novel fan theft-resistant link chain, including voltage input end and voltage output end, voltage input end and voltage output end
Cabin theft-resistant link chain is all connected, it is characterized in that：Also include wheel hub and become oar theft-resistant link chain, time-delay relay, diode first, controller, tooth
Roller box hypervelocity module, generator hypervelocity module and diode second,
Wheel hub becomes both ends after oar theft-resistant link chain, time-delay relay, diode first and controller are contacted and connected successively and connected respectively
Voltage input end and voltage output end are connect, gear-box hypervelocity module, generator hypervelocity module and diode second are sequentially connected in series and gone here and there
Both ends connect wheel hub and controller respectively after connection；Controller also distinguishes tooth connection roller box hypervelocity module and generator by signal wire
Exceed the speed limit module.
Described novel fan theft-resistant link chain, it is characterized in that：The output of the output voltage and voltage output end of voltage input end
Voltage is all direct current 24V.
The utility model in use, implement as follows：Gear-box hypervelocity module and generator hypervelocity module are set respectively
In in gear-box and in generator, when gear-box or generator hypervelocity, gear-box hypervelocity module or generator hypervelocity module are sent out
To controller, controller judges whether to exceed the speed limit the number of delivering letters, if judging to have exceeded the speed limit, controller sends finger to time-delay relay
Order, the normally-closed contact of time-delay relay disconnect, and make gear-box or generator out of service, and controller also has fault message record
And its function of instruction is provided according to judged result, cabin theft-resistant link chain can remote reset.
The characteristics of the utility model, is as follows：
1. theft-resistant link chain hardware requirement increase Time Delay Opening theft-resistant link chain loop in parallel on the loop of easy wrong report hypervelocity
（Malfunctioned with the anti-hardware-in-the-loop of diode）With Time Delay Opening delay while controller receives generator and gear-box exceeds the speed limit
Relay trigger acts.
2. after master control receives generator or gear-box overspeed signal, primary control program is started to calculate and judged with PID immediately
Whether unit exceeds the speed limit（According to primary control program software hypervelocity setting valve and time hypervelocity linear logic）.If time-delay relay is delayed
Time arrives（Equipment safety chain is opened）Or controller judges that unit exceeds the speed limit, controller OK signals are opened（Equipment safety chain is opened
Redundancy is set）And provide and put away the oars and braking commands（Master control can also increase according to generator speed to throw brake, can drop significantly
Low brake and prevents fire at pad wear）.If primary control program judges to be due to hypervelocity hardware hypervelocity module（Due to vibrating wink
Between loose contact or detected value bounce）When causing hypervelocity, primary control program provides overspeed alarming mistake, unit normal operation.
3. personal safety chain（Jerk）Scene reset, equipment safety chain must be arrived（Equipment safety chain can be by primary control program
DTC and brake grade program are realized）Can be with remote reset.
The utility model is used to prevent generator and gear-box hypervelocity module from having irregular operation（Mainly due to hypervelocity mould
Block long operational time, runnability are low）Situation and hypervelocity setting valve amplitude are set can not excessive situation.Avoid due to the event that exceeds the speed limit by mistake
Barrier causes unit frequently to be put away the oars, brake shutdown and influence generated energy.New theft-resistant link chain will increase master control system and judge generator or tooth
Roller box rotating speed brakes to select to throw, and can greatly reduce brake pad wear and fire.Ensure that fan safe is run.In order to service people
Member's personal safety and convenient service, personal safety chain must arrive scene reset, and equipment safety chain can remote reset function.
