Fire plant is put out a fire.
The control system of above-mentioned existing fire-fighting fire extinguishing has the following deficiencies: 1, the control of two sets of temperature sensing cable logic sums
Mode is malfunction in order to prevent, but the case where can equally bring tripping, regardless of being that malfunction or tripping can all cause to put out a fire
Not in time；2, the cause of fire is varied, although temperature sensing cable has been distributed among three most impacted places, this three
A place and nisi cause once fire occurs elsewhere, or even cause open fire not affect temperature-sensitive electricity for the moment but
Cable, so that it may be delayed fire extinguishing opportunity, largely effect on the reliable and stable operation of flexible direct current converter station.
Summary of the invention
The purpose of this utility model is that according to prior art shortcoming and providing a kind of prevents malfunction from preventing
Tripping, increase defense controls is comprehensive, ensureing flexible direct current converter station, reliable, stable operation the flexible direct current converter station change of current becomes
Depressor Novel firefighting control device.
Purpose described in the utility model is realized by following approach:
A kind of flexible direct current converter station converter power transformer Novel firefighting control device, including form as follows:
1) two sets of cable linear temperature sensing cables, bilayer, which is distributed and is wrapped in the change of current, becomes ontology and various components, including the change of current
