Description
Technical field
The present invention relates to a kind of high pressure soft starter device, be specifically related to a kind of armoured flame-proof type flexible starting equipment.
Background technology
Along with the variation of coal market, the down-hole power load is doubled and redoubled, but is subjected to the electric power system capacity impact that formed, often be difficult to satisfy the down-hole high-power in the start request of piezoelectricity machine.Do not carrying out under the situation of network system reorganization and expansion, the best approach that solves the medium-pressure or high pressure electric motor starting is implemented soft start exactly.
Present domestic flame-proof mine high pressure soft starter device has following several types:
(1) saturable reactor mode.
A. the saturable reactor mode is to change the anti-value of its point by change magnetic saturation unshakable in one's determination, thus the dividing potential drop of change and motor.During with fixing reactor starting, voltage is nonadjustable.Along with the acceleration of motor, starting current will descend, if the net capacity deficiency is easy to cause starting failure, or impact when switching to total head very big.Saturable reactor is compared with the constant reactance device, only is that its can holding current descend, but can cause starting failure (or the starting time is long, or impacts when switching excessive), also will see the selection of maximum reactance value.Maximum reactance value choosing littler, the possibility of starting failure is little, but impacts greatly when closing a floodgate; It is big that maximum reactance value selects, and then causes starting failure easily.Saturable reactor can not be called the soft start product thus, can only be the decompression starting product better than reactor.
B. heating problem, saturable reactor always works near the saturation region, and magnetic flux unshakable in one's determination is very big, and iron loss is very big.Because heating, starting performance is with non-constant continuously.
C. saturable reactor can only be with constant current mode operation, and electric current can not be less, so when powering on electrical network is had impact, motor speed also rises to a certain numerical value quickly.
D. saturable reactor is by the dividing potential drop decompression starting, and motor terminal voltage is relevant with capacity motor (impedance), and every motor gets and singly joins reactor, can not accomplish " one drag many ".
(2) controllable silicon tandem soft start.
The circuit form of this mode is to select for use many controllable silicon series connection to solve single silicon controlled problem of withstand voltage.The starting performance of this device can reach omnibearing soft starting characteristic, and promptly voltage, electric current can both be from zero adjustable continuously, can exempt fully to the impact of electrical network with to the impact of motor and plant equipment, and control is flexible, the repeatable accuracy height.But owing to technical reason, this mode remains in following shortcoming:
A. owing to adopt many controllable silicon series connection, all press problem very high, be not easy to be guaranteed the coherence request of every thyristor characterisitic parameter for solving.Element characterisitic parameter in use for some time also can change, and makes and all presses degradation, is easy to cause the damage of only single or whole arm thyristor, so the reliability of this device is relatively poor.
B. harmonic ratio is bigger.
Though c. this device has flame-proof mine, price is very expensive for above-mentioned reasons, and the expense of follow-up spare part is also very high, so maintenance cost is very big.
Summary of the invention
The purpose of this invention is to provide a kind of economic benefit and practical function better and can realize the armoured flame-proof type flexible starting equipment of " one drag many " mode or the soft start of dual power supply mode.
The technical scheme that realizes the object of the invention is: a kind of armoured flame-proof type flexible starting equipment, comprise the main body Flameproof box that is used to be provided with soft starter device, and described main body Flameproof box comprises main chamber, high pressure inlet wire chamber, high-voltage terminal chamber; Establish the split Flameproof box of high-pressure vacuum contactor in this device also comprises, described split Flameproof box comprises split master chamber, at least one split high pressure inlet wire chamber and at least one split high-voltage terminal chamber; The top of described main body Flameproof box also is provided with one and drags many wire connection cavities.
