Specific embodiment
Drawer unit prevents unexpected separating brake/combined floodgate guard system under claimed low-voltage distribution cabinet electric operating, Closing switch by using electromagnetic and mechanical locking device and with key, the on off state linkage with breaker is got up, and realizes electricity Protection question of the drawer unit of dynamic operation to unexpected separating brake/combined floodgate.The system is mutually tied by mechanical device and electrical control Close what is realized, electrical control prevents the unexpected separating brake, mechanical device from preventing unexpected combined floodgate.With reference to attached in the embodiment of the present invention Figure, is described in further detail to technical scheme.
Fig. 1 is of the invention to prevent unexpected brake-dividing system electric control theory schematic diagram.Device is locked including electromagnetic and mechanical DS;Electromagnetic and mechanical locking device DS be connected with circuit breaker Q F, and the motor-operating mechanism CD of connecting drawer unit power supply, That is connection motor-operating mechanism plant-grid connection point P1, P2;When circuit breaker Q F is closed, electromagnetic and mechanical locking device DS obtains electric lock It is fixed, drawer unit is locked together with cabinet body frame, drawer unit can not be pulled out;When circuit breaker Q F disconnects, electro-magnetic mechanical lock Determine the unblock of device DS dead electricity, drawer could be pulled out, it is to avoid extract drawer out in closing position, and unexpected separating brake powers off current supply circuit.
Wherein, electromagnetic and mechanical locking device uses Permanent Magnet and Electric magnetic padlock, circuit breaker Q F comprising breaker closing auxiliary magnet OF1 and The plant-grid connection point for disconnecting auxiliary magnet OF2, breaker closing auxiliary magnet OF1 and Permanent Magnet and Electric magnetic padlock DS is connected, when circuit breaker Q F is closed Close, closure auxiliary magnet OF1 is closed and disconnected auxiliary magnet OF2 disconnections, and electromagnetic lock DS obtains electric, dead bolt ejection, by drawer unit and cabinet Body framework is locked together;When circuit breaker Q F disconnects, closure auxiliary magnet OF1 disconnects and disconnects auxiliary magnet OF2 closures, electromagnetic motor lock DS Dead electricity is unlocked.
Motor-operating mechanism CD has closing circuit access point S2 and sub-gate circuit access point S3, closing circuit access point S2 The local manually operated switch knob STT or remote control switch knob DO1 of connection, sub-gate circuit access point S3 connections are manually operated Opening button STP or remote control opening button DO2;When manually operated switch knob STT closures or remote control switch knob When DO1 is closed, motor-operating mechanism CD closing circuits obtain electric so that circuit breaker Q F is closed, closure auxiliary magnet OF1 closures, disconnect Auxiliary magnet OF2 disconnects, and electromagnetic and mechanical locking device DS obtains electric, and dead bolt ejection makes drawer form mechanical latching with cabinet body frame, protects Holding drawer can not be drawn out at breaker closing position;When manually operated opening button STP and remote control opening button When DO2 is closed, motor-operating mechanism CD sub-gate circuits obtain electric, disconnect circuit breaker Q F, are closed at auxiliary magnet OF1 disconnections, electricity Magnetic mechanical locking device DS dead electricity, dead bolt is retracted, and drawer is released with cabinet body frame mechanical latching, and drawer can be pulled out.Wherein, far Process control switch knob DO1 and the inside relay that remote control opening button DO2 is the acquisition module in drawer unit The node of device, remote control is realized by the communication interface on acquisition module.
In addition, the system also sets up combined floodgate indicator lamp HR, separating brake indicator lamp HG, combined floodgate indicator lamp HR is red light, and separating brake refers to Show that lamp HG is green light.Closure auxiliary magnet OF1 connection combined floodgate indicator lamp HR, when circuit breaker Q F closures, closure auxiliary magnet OF1 is closed, Combined floodgate indicator lamp HR when reds, the state that display circuit breaker Q F closes a floodgate;Auxiliary magnet OF2 connection separating brake indicator lamp HG are disconnected, when disconnected Road device QF disconnects, and disconnects auxiliary magnet OF2 closures, and separating brake indicator lamp HG green lights show the state of circuit breaker Q F separating brakes.
To prevent unexpected combined floodgate, iPanel low-voltage distribution cabinet drawers unit of the invention from preventing unexpected combined floodgate system, including Closing switch with key, the closing circuit of the motor-operating mechanism of the closing switch connecting drawer unit with key is accessed Point S2;When drawer is pulled out to be overhauled, breaker is off, and is pinned closing switch by key, even if drawer is surprisingly closed Close, breaker is still within open position, it is to avoid unexpected combined floodgate, harm maintenance people are surprisingly closed due to drawer in open position The safety of member.Wherein, the closing switch with key uses commercially available key switch.Use for convenience, by the key of key switch Hole is arranged on the drawer unit front panel.When maintainer needs subordinate loop to overhaul, drawer unit, open circuit are extracted out Device is in off-state, and by button in key rotation lock, button can not be pressed, closing switch is pinned, then closing circuit Not can turn on.The key of closing switch is taken care of by maintenance personal, accordingly even when someone surprisingly closes drawer, breaker is still located In open position, lower mouth is not charged, it is ensured that the personal safety of maintainer.After the completion of maintenance, rotated by key and unlocked, pressed Button is pressed, and closing circuit is connected.
It should be pointed out that the above specific embodiment can make those skilled in the art that this hair is more fully understood It is bright, but do not limit the invention in any way.Those skilled in the art still can modify to the present invention or equally replace Change, all technical schemes for not departing from the spirit and scope of the present invention and its change, it all should cover in protection model of the invention In the middle of enclosing.
