Description
Technical field
The utility model relates to 3200MVA surge generator cooling water system fields.
Background technique
Chilled water unit is one of 3200MVA short-circuit impact testing electricity generation unit important component, the stabilization of operation
Can property and reliability are directly related to generator safe and stable operation.3200MVA impact type power generation machine chilled water unit is to use
To cooler of electric motor and oil cooler reliably provide the device of cooling water, and can guarantee automatically control cooling water pressure,
The parameters such as temperature and its flow guarantee heat caused by 3200MVA impact type power generation machine, dragging motor and lubricating oil (power generation
Machine, dragging motor bearing shell) caused by heat be pulled away, operate normally 3200MVA impact type power generation machine and dragging motor.Such as
These heats of fruit cannot be pulled away, and the harm generated to entire unit is very big.Existing design is in chilled water unit
The signals such as pressure, temperature are shown on the spot, do not pass to master control room, are unfavorable for monitoring.Pick-up has been gradually added in developing deeply
Device can upload to master control room, but signal is distributed transmission, and the degree of automation is not high.Therefore research and develop a kind of performance it is stable,
Reliable chilled water unit, is necessary.
Summary of the invention
The purpose of this utility model is to provide the device of essential raw cooling water to cooler of electric motor and oil cooler, and can monitor
With the parameters such as pressure, temperature and its flow of control cooling water, to guarantee that impact type power generation machine and dragging motor operate normally.
The technical solution of the utility model is: a kind of 3200MVA surge generator chilled water unit, by lower header (1), exchange water pump
(2), spare exchange water pump (3), cooling tower (4), oil cooler (5), cooler of electric motor (6) form, and pass through pipe between each component
Road connection, and observing and controlling component is set, lower header (1) outlet is connected to motor AC water pump (2) and exchanges water pump (3) with spare, hands over
Flowing water pumps (2) and exchanges water pump (3) parallel connection with spare, and outlet connection cooling tower (4) passes through cooling tower (4) cooling water by oil
Cooler (5), cooler of electric motor (6), are eventually returned to lower header (1), complete a closed cycle, oil cooler (5) and motor
Both coolers (6) are in parallel.
Working principle: system using an independent closed circulation system by being formed, and at runtime, water is boosted laggard by water pump
Enter cooling tower, by the water of cold water tower cooler, is supplied to turbine flowmeter and arrives oil cooler, generator cooler and dragging electricity again
Machine cooler returns to lower header and completes a closed cycle.
Technical effect: the design of 3200MVA impact type power generation machine chilled water unit is the mistake of a sequencing and fining
Journey, the device are made of independent closed cycle circuit, and thermal resistance, thermometer, pressure gauge, pressure are respectively provided on the pipeline of device
The temperature of water, pressure, flow teletransmission to master control room can be joined control cabinet in design by power transmitter, turbine flowmeter,
After all signals are aggregated into control cabinet, thus one-line teletransmission to master control room realizes the monitoring in master control room.The design device
Meet the requirement of various experiment station's unit reliabilities of operation, safety, and system structure is simple, is easily installed, safeguards, examines
It repairs.
Detailed description of the invention
Fig. 1 is 3200MVA surge generator chilled water unit flow chart
Specific embodiment
As shown in Figure 1, a kind of 3200MVA surge generator chilled water unit, device is by lower header 1, exchange water pump 2, standby
It is formed with exchange water pump 3, cooling tower 4, oil cooler 5, cooler of electric motor 6, the cooling water in lower header 1, through 2 liters of water pump of exchange
After pressure, oil cooler 5, cooler of electric motor 6 are flowed into through the water after cooling of cooling tower 4 by cooling tower 4, generator, dragging
Heat caused by heat and lubricating oil caused by motor (generator, dragging motor bearing shell) is taken away, and lower header is then return to
1, complete a closed cycle.Turbine flowmeter, thermal resistance, thermometer, pressure transmitter etc. are also equipped on water system pipeline,
The temperature of cooling water, pressure, flow can be shown on the spot and automatic remote transmission is to master control room.Cooling can be monitored in master control room
The temperature of water, pressure, flow.
Specific embodiment: below by taking the utility model supplies water to the cooler of surge generator and dragging motor as an example, into
One step illustrate working principle of the utility model is: chilled water unit rise machine when do not put into operation, when generator unit stator, turn
When son and lubricating oil temperature are high, then put into operation.When putting into operation, cooling water system has an independent Water Pump Circulation System, gives
Oil cooler, cooler of electric motor provide cooling water.
Surge generator, dragging motor and oil cooler cooling water system be equipped with two and centrifugal corrosion-resistant exchange water pump
2 and 3, the two mutual backup.This pump is set to what the cooling water system of surge generator, dragging motor and oil cooler supplied water
It is standby.
The intelligent integral turbine flowmeter being equipped in system is to surge generator, dragging motor, oil cooler and cool
The cooling water system of water tower provides the equipment of flow teletransmission.Intelligent integral turbine flowmeter can show on the spot instantaneous flow and
Integrated flux, band Protection Counter Functions, and energy teletransmission can monitor the flow of cooling water system, intelligence to master control room in master control room
The integrated turbine flowmeter of energy is installed on the pipeline, and is easily installed, observes, is safeguarded.
When putting into operation, cooling water is by flowing through pressure after alternating current generator water pump 2 or the boosting of spare exchange water pump 3
Transmitter, into cooling tower 4, through the water after cooling of cooling tower 4 after eddy-current flowmeter, into oil cooler 5, motor is cold
But device 6 bring out the heat of oil by the cold and hot exchange of grease, and last cooling water returns to lower header 1, completes an enclosed and follows
Ring.Chilled water unit is equipped with pressure, temperature, the display on the spot of flow and teletransmission to master control room all the way for this.In master control room just
It can monitor the temperature, pressure, flow of chilled water unit.Wherein pressure transmitter is cold to surge generator, dragging motor, oil
But the cooling water system of device and cooling tower provides the equipment of pressure teletransmission；Intelligent integral turbine flowmeter can show wink on the spot
