Pressure hands over the nucleus equipment of straight electric energy conversion.Thyristor in transverter can produce substantial amounts of heat in running, if
Radiate bad, cause the temperature of IGCT valve block to exceed the maximum junction temperature allowed, its change of current performance, which will deteriorate, even results in member
Part damages.Therefore the problem of cooling of transverter is one of HVDC transmission system safe and reliable operation most important.Water
The cold type of cooling is that current commutation valve is cooled down by the way of, and the stable operation of main pump is most important to converter valve valve cooling system.
Main pump uses centrifugal pump of horizontal axis, and because axle envelope installs reason or long-play, slight seep water to tight occurs at main pump axle envelope
Weight drainage, the safe and stable operation to high voltage direct current converter valve bring huge potential safety hazard.
At present, the main pump leakage inspector of the cold use of Converter Station Valve, be made up of a water storage tank and liquid-level switch, its
Come with some shortcomings part in operation：Leak needs the full water storage tank of drop just to alert, and alarm not in time, can not judge main pump leak
With the presence or absence of degradating trend.
Utility model content
The purpose of this utility model is the energy in view of the above-mentioned problems, provide a kind of converter valve cold main pump leakage inspector
Enough solve main pump water leakage alarm not in time, can not real time inspection main pump leak speed the problem of, improve converter valve cooling system
Stable operation.
To realize object above, the utility model adopts the technical scheme that：
A kind of cold main pump leakage inspector of converter valve, including ponding funnel below main pump axle envelope, positioned at product
Water storage tank below hyponome and the drainage tube for connecting ponding funnel and water storage tank, in addition to weighing sensor, weigh
Sensor amplifier and the cold Control protection system of converter valve, the weighing sensor is arranged on the lower section of water storage tank, described to weigh
The electrical connection of the input of the output end of sensor and weighing sensor amplifier, the output end of the weighing sensor amplifier and
The cold Control protection system electrical connection of converter valve, the cold Control protection system of converter valve have weight metering module, memory module
And alarm module.
Preferably, capping and draining valve are provided with the water storage tank.
Preferably, the cold Control protection system of the converter valve is additionally provided with wireless communication module.
The beneficial effects of the utility model are：
1st, main pump water leakage situation is detected using the change of weight, detection efficiency is high, and weighing sensor amplifier can carry
High detection sensitivity, water-leak alarm signal can be sent in the slight leak of main pump, improves emergency response speed.
2nd, the cold Control protection system of converter valve can be prompted to lead by weight change in the unit of account time to staff
Whether pump leak has degradating trend, can also upload the newest water leakage situation of main pump in real time to mobile terminal or Surveillance center, just
Analyzed in staff.

Embodiment
Content of the present utility model is described in further details with reference to the accompanying drawings and detailed description.
Embodiment：
It refer to shown in Fig. 1, a kind of cold main pump leakage inspector of converter valve, including ponding funnel 1, drainage tube 2, product
Tank 3, weighing sensor 4, weighing sensor amplifier 5 and the cold Control protection system 6 of converter valve.Ponding funnel 1 is located at main pump
The lower section of axle envelope, for collecting main pump leak.The bottom of ponding funnel 1 is connected by drainage tube 2 with the top of water storage tank 3, for inciting somebody to action
Water collected by ponding funnel 1 is sent in water storage tank 3, and water storage tank 3 has capping and draining valve (not shown).Weigh
Sensor 4 is located at the lower section of water storage tank 3, for weighing leak weight, the input of weighing sensor amplifier 5 by cable 7 with
The signal output part of weighing sensor 4 is connected, for changing and amplifying leak weight signal, weighing sensor amplifier 5 it is defeated
Go out end by the Control protection system 6 cold with converter valve of cable 7 to be connected, the leak weight signal after amplification is transmitted cold to converter valve
Control protection system 6.The cold Control protection system 6 of converter valve is provided with weight metering module, memory module, alarm module and channel radio
Believe module, weight metering module is used to measure leak weight and calculates leak weight rate, and memory module is used to store in real time
Leak weight and leak weight rate, alarm module are used to send Lou when leak weight is more than the main pump leak weight of setting
Water alarm signal, and when the weight of water storage tank setting value full close to water storage tank water, send the full alarm signal of water storage tank water, nothing
Line communication module is used to send alarm signal and leak weight rate to mobile terminal or Surveillance center, is easy to work people
Member's analysis.
The course of work of the present utility model is as follows：
Leak occurs at main pump axle envelope, all water leaked out will be all dropped in ponding funnel 1, due to ponding funnel 1
