TKDG series hoister ac electric equipment
1, scope and purpose
TKDG series hoister exchange control equipment and JK series coil
type induction-motor-driven hoist hoister supporting the use of
control equipment, can satisfy the coil type induction-motor-driven
hoist hoister of starting - a reasonable - slow - parking and
reversing the running state of control requirements and reliable
safety work, conforms to the ac drive mine hoister control
equipment technical conditions and coal mine safety rules, our
company is according to user requirements, the frequency and relay
configuration of PLC control in three different grades and
technical performance of electric equipment.
Electric equipment is suitable for indoor and other places, and
installation of explosion-proof electric equipment routine work
conditions.
2,the meaning of the model
3, technical performance and parameters
TKDG series of mine hoister control equipment adopts double power
lines and control ascension into the motor is turning, inversion,
starting, speed and braking operation state, realize hoister normal
operation. With the ac drive mine hoister control equipment
technical conditions and coal mine safety rules and requirements of
short circuit, overload, pressure loss, speeding, zero interlocking
shoe wear, spring, fatigue, and brake oil pressure, manchang speed
wire, depth indicator, and other protection fault memory function,
ensure the machine work. And according to the requirements of users
can add dynamic braking device and backup protection.
Relay control using contactor, relay to control the function
requirements of ascension operation, the system has low content of
technology, easy installation and maintenance, the advantages of
simple operation.
Frequency conversion control adopts inverter control realization
ways functions and ascend chance, its biggest advantage for
advanced technology, energy-saving effect, achieve the five-level
speed.
PLC control adopts advanced technology to realize the control of
the function and ascend chance did little to demand, the biggest by
programmable controller, complete control functions, stable
performance, low malfunction, safety performance is high, can
achieve double line protection, through the network can also be
remote guidance and service.
