The electric control system consists of electric control box,
electromagnetic braking motor and handle swithetc. The upward and
downward movement of suspended platform is controlled by two
electromagnetic braking motors.

5. Product Feature
End Carriage Control Panel fixed AC metal enclosed switchgear
(short for panel as below) is a new product designed and developed
by NANTE MACHINERY, based on the introduction of advanced foreign
design and manufacturing technology. It applies to 3.6~12kV three
phase AC 50Hz single busbar or single busbar sectional transport,
distribution system, as for receiving and distributing power
energy, and realize to control, monitor and protect power circuit.
It is widely used for power plant, substation, petroleum,
metallurgy, chemical, natural gas and other civil field.
6. Structure feature:
1. END CARRIAGE CONTROL PANEL series is metal enclosed fixed
switchgear, the body is welded with angle steel and steel board,
inner and outer coating is solid by static spray plastic powder.
2. This panel conforms to GB3906 3-35kV AC Metal enclosed
switchgear and international standard IEC62271-200 besides, prevent
from opening and closing connecting switch with load, prevent from
opening and closing circuit bre aker, prevent from entering into
interval with electricity, prevent from closing earthing switch
with electricity (five protections adopt simple, reliable
mechanical interlock device). The power indicator is installed in
front of panel which reflect voltage in the side of circuit. When
circuit side with electricity, lock the enclosed board and panel
3. Same type product and structure component can exchange each
1 The inner structure of panel is divided into circuit breaker
compartment, busbar compartment, cable compartment ,relay
compartment, use steel plate to separate panels. Use eddy current
steel plate and epoxy resin busbar bushing to separate panel.
2 The panel adopts cold roll steel sheet and angle steel to weld
together, without reticulation fabric, non-flame-resisting
materials. Outer insulating creeping distance of components and
supporting insulator, pure porcelain insulation 1.8cm/kV, organic
insulation 2.0cm/kV.The air distance of phase to phase, phase to
earth 125mm. There is an intelligent hygrothermoscope to start or
stop heater according to the humiture condition of circuit breaker
compartment and cable compartment in panel, Prevent from forming
moist and high temperature.
3 There is a viewing port for observing of closed and open position
of upper, down connecting switch without open the door. The panel
is double maintenance, inspect relay compartment equipments,
operating mechanism, mechanical interlock and transmission part in
front, inspect main busbar, shunt circuit busbar, cable terminal,
connecting switch and earthing switch.
4 Circuit breaker: The circuit breaker is located in the middle
part, disconnecting switch and earthing switch and interlock
mechanism are above it, and with indicator device, describe open
and closed position.
5 Transformer: CT is mounted on the underpart of front side,
connect with circuit breaker and connecting switch, main loop
without electricity. It can carry out preventive test, inspection
and exchange, the secondary wire of CT to earth reliably .
6 Disconnect switch and earthing switch: connecting switch,
disconnect switch and earthing switch can be seen t hrough viewing
port, controlled by a set of manual operating mechanism to assure
of program and reliable locking for circuit breaker, disconnect
switch and earthing switch, meet the requirement of five
7 Measuring instrument, relay protection, monitor device and
auxiliary circuit .
8 Earthing: It takes a consideration of 440mm copper busbar as
earthing body along with whole width of all panel extending.
