Circuit；
Emergency stop controlling power circuit include power circuit breaker, power circuit breaker entrance connection single phase alternating current power supply, outlet according to
Secondary connection surge suppressor and AC/DC conversion electric powers, AC/DC conversion electric powers output DC control supply；
Emergency stop control loop include be sequentially connected in series first fuse in DC control supply, switch board scram button,
Working site emergency stop summarizes dry contact, user's emergency stop dry contact and the first relay；Working site emergency stop summarize dry contact by
One group of scram button for being located at working site is in series；
It is normally closed tactile that emergency stop cut-off loop includes the second fuse being sequentially connected in series in single phase alternating current power supply, the first relay
Point, auxiliary contacts of circuit breaker and shunt release coil.
Further, the emergency stop cut-off loop is also comprising the second relay, one end of the second relay coil and second
Fuse output terminal is connected, another termination zero；The normally opened contact of second relay is used as alarm dry contact.
Further, for the emergency stop cut-off loop also comprising indicator light, one end of indicator light and auxiliary contacts of circuit breaker are defeated
Outlet is connected, another termination zero.
The beneficial effects of the utility model are：
First, emergency stop control loop summarizes emergent stop signal subregion, and passes through the realization of the first relay and emergency stop is cut off back
The control of shunt release coil in road, then disconnect breaker by shunt release, cut-out compressor power circuit；It can not only
Enough ensure that emergency stop is assuredly shut off compressor power circuit, while easily investigation emergency stop source；
The 2nd, if emergency stop failure is not excluded for, then breaker is then off always, it is impossible to be powered, be protected to compressor
Demonstrate,prove security；
3rd, the second relay is introduced in emergency stop cut-off loop and generates alarm signal, can find that emergency stop is cut off back in time
Whether road is normal.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples：
Fig. 1 is the electronic schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, the utility model provides compression electrical-mechanical system interlocking emergency stop device, 380V three-phase alternating current power electrics
Source is powered by circuit breaker Q F1 for compressor 1, and circuit breaker Q F1 carries shunt release；The emergency stop device is controlled comprising emergency stop
Power circuit, emergency stop control loop and emergency stop cut-off loop.
Emergency stop controlling power circuit include power circuit breaker QF2, power circuit breaker QF2 entrances connection single phase alternating current power supply,
Outlet is sequentially connected surge suppressor SPD and AC/DC conversion electric powers N1, AC/DC conversion electric power N1 output 24V DC control electricity
Source.
Emergency stop control loop includes the first fuse FU1 being sequentially connected in series in 24V DC control supplies, switch board emergency stop
Button S1, working site emergency stop summarize dry contact K3, user emergency stop dry contact K4 and the first relay K1；Working site emergency stop
Summarize dry contact K3 by one group be located at working site scram button it is in series, can pre-set wire connection terminal X1.1,
X1.2 is used to be connected with the scram button head and the tail both ends connected；
The emergency stop that the miscellaneous equipment of workspace user generates is aggregated into a user emergency stop dry contact K4, can pre-set
Wire connection terminal X1.3, X1.4, for being connected with user's emergency stop dry contact K4.
It is normal that emergency stop cut-off loop includes second fuse FU2, the first relay being sequentially connected in series in single phase alternating current power supply
The shunt release coil of closed contact K1, circuit breaker Q F1 auxiliary contact and circuit breaker Q F1.Emergency stop cut-off loop is also comprising the
