Description
Technical field
The utility model relates to a kind of equipment in mining technique industry, especially relates to a kind of auxiliary shaft intelligences combination and switches cabinet.
Background technology
Auxiliary shaft hoisting is the throat thoroughfare in coal production transportation, is also one of key link.With regard to the lifting owner electric-control system that national colliery uses, still generally use interchange winding motor rotor series resistance speed control system, because auxiliary shaft is related to worker's life security of going into the well, so be generally all designed to the same mair motor of two technical parameters, one with, another is for subsequent use.When mair motor break down or overhaul, fall machine need to switch mair motor time, circuit between two motors switches more loaded down with trivial details, must be gone down by the workman be skilled in technique, remove the cable end of the original mair motor in high pressure commutation room, press by mair motor cable end, phase sequence is easily got wrong on the one hand, often tears pressure-volume on the other hand open and easily makes cable end damage leave severe compromise.Mair motor rotor cable also will change by tearing open to overwhelm, equally also there are the problems referred to above, the time wants more than 20 minutes at the soonest, not only increases the labour intensity of maintenance personal, and extend the processing time of fault, all bring to safety in production and management unfavorable greatly.
Because auxiliary shaft hoisting uses relatively backward interchange winding motor rotor series resistance speed control system; slowing down and the speeds control poor-performing of crawling phase; particularly be difficult to when load change realize permanent feed speed control, often can cause and put and overwind trouble.Hoister starts and braking operation process frequently, also makes rotor series resistance speed produce quite serious energy consumption; Rotor series resistance speed control circuit is complicated, contactor, resistor, and coiling electric motor brush etc. easily damage, and affect Safety of Coal Mine Production, cause the increasing of production cost.
Summary of the invention
Technical problem to be solved in the utility model is to provide and a kind ofly saves the energy, facilitate slotted eye and the auxiliary shaft intelligences combination reduced costs switches cabinet.
The technical scheme in the invention for solving the technical problem is: a kind of auxiliary shaft intelligences combination switches cabinet, and described switching cabinet comprises between high-voltage variable frequency power source cabinet, high-pressure frequency-conversion transformer case, high-voltage ac power cabinet, high voltage frequency conversion power unit cabinet, high pressure commutation, high voltage frequency conversion system and AC system switch cabinet, thing platform motor and crosstalk and hinder and switch cabinet, East Platform motor and West Platform motor;
Described high-voltage variable frequency power source cabinet by signal transmission to high-pressure frequency-conversion transformer case, described high-pressure frequency-conversion transformer case by signal transmission to high voltage frequency conversion power unit cabinet, described high-voltage ac power cabinet sends signal transmission to high voltage frequency conversion power unit cabinet, between described high voltage frequency conversion power unit cabinet and high pressure commutation, signal transmission is switched cabinet to high voltage frequency conversion system and AC system, described high voltage frequency conversion system and AC system switch cabinet and are hindered to thing platform motor and crosstalk by signal transmission and switch cabinet, described thing platform motor and crosstalk resistance switch cabinet by signal transmission to East Platform motor and West Platform motor.
Concrete further, described combination is switched cabinet and is controlled by PLC system.
The beneficial effects of the utility model are: after have employed above-mentioned switching cabinet, switch electric-control system and mair motor does not need to tear voltage cable open at every turn, eliminate potential safety hazard, even also can end of operation within the operation that switching time all must be completed by original technology master-hand for more than 20 minute to new worker 3 minutes, improve work efficiency, ensure that the safe and reliable running of auxiliary shaft, increase load-carrying capacity, create huge economy and safety benefit.
