It is arranged at the socket 7,8 of the bottom of box；
It is arranged at the relay 13, breaker 14 and mutual inductor 15,16 of the box house.The utility model is inserted by double
Seat can realize large capacity (300A) electric energy transmission, can be locally displayed in real time accident network use when size of current, have unidirectionally give
Electricity Federation lock function, has the characteristics that multimode instruction, good man-machine interface.
In one embodiment of the utility model, generator end connecting box of meeting an urgent need further includes：
The damper 11 at the babinet back is arranged at, the babinet is installed on the bulkhead in required place by damper
On, it is typically located in the cabin of generating set.
The electric energy of marine generator group conveying is met an urgent need connecting box by fixed cable transfer to generator end, is controlled by it defeated
Sent to subordinate and met an urgent need connecting box by flexible cable of the both ends with socket after going out, realize transmission, the real-time display instruction of accident electric energy
The functions such as accident network working status, facilitate operator to use.In addition, the utility model can detect and be locally displayed in real time accident electricity
Power net operating current, and it is passed to higher level's monitoring system.
Generator end is met an urgent need, and connecting box mainly has the transmission of large capacity electric energy, job control, unidirectional power transmission interlocks, electric current is examined
Survey, the function such as state instruction and short-circuit protection, its outline drawing as shown in Figure 1, internal layout as shown in Fig. 2, electrical principle line
Road figure is as shown in Figure 3.
In one embodiment of the utility model, specific each function is realized as follows：
(1) large capacity electric energy transfer function:Generator end meet an urgent need connecting box pass through the double socket 7,8 on its babinet with it is exterior
Two flexible cables (non-the utility model device) with plug are connected, and realize that 300A accidents electric energy transmits.With transmitting 150A before
Accident electric energy is compared, and electric energy transmission quantity is double.
(2) job control function：Control loop is equipped with " control handle " 1, when without using accident distribution system, " control
The selection of knob " 1 to " stopping " position, control loop cannot close a floodgate without electricity, breaker 14 because of undervoltage tripping；Match somebody with somebody when using accident
During electric system, the selection of " control handle " 1 to " work " position, control loop is devoted oneself to work.
(3) unidirectional power transmission interlock：Generator end meet an urgent need connecting box power supply direction only allow from switch-side send to insert
Seat side, its realization principle are as follows：
A) when switch-side have electricity and socket side without electricity when, " generator side power supply " white indicating light 2 is bright at this time, KA relays
Device 13 is failure to actuate, and the undervoltage trip coil (circuit breaker internal) of breaker 14 obtains electric through 13 normally-closed contact of KA relays, it is allowed to closes
Lock.
B) after breaker 14 is closed a floodgate by switch knob 9, socket 7 and 8 has electricity, and KA relays 13 are attracted, normally-closed contact
Disconnect, the undervoltage trip coil of breaker 14 is maintained to power by its auxiliary contact OF (circuit breaker internal), at this time " normal operation "
Green indicator light 6 is bright, and generator normally conveys electric energy to accident power network；
C) there is electricity when breaker 14 closes front socket side, then " socket side power supply " white indicating light 3 is bright, and " No switching on " is red
Color indicator light 4 is bright (warning No switching on operation), then no matter whether switch-side has electricity, and breaker 14 is because KA relays 13 are dynamic
Make, breaker undervoltage trip coil dead electricity and can not close a floodgate.If carry out closing operation in this case, " switch trip " is yellow
Color indicator light 5 will be lighted (closing operation can not be carried out at present by reminding).
D) when equipment non-transformer input, breaker 14 because coil without tension can not obtain it is electric dropout and disconnect automatically, all instructions
Lamp does not work.
(4) current sense function：By current transformer 15 and 16, generator end is met an urgent need connecting box output two-way electric current letter
Number to main distribution board, for detecting and monitoring the current-carrying size of accident power grid actual negative.Generator end, which is met an urgent need, patches box panel
Ammeter 10 is set to be used to monitor in real time and the size of accident network load electric current is locally displayed.
(5) state-indicating function：One of auxiliary contact of breaker 14 provide all the way to Power Station Monitored Control System on ship
Switching signal is switched, whether the accident power grid of being used to refer to puts into operation.
(6) short-circuit protection function：Breaker 14 is the only breaker with short-circuit protection, and No-mistake Principle defencive function is short-circuit to divide
Cutting capacity is 150kA.
Each embodiment is described by the way of progressive in this specification, what each embodiment stressed be and other
The difference of embodiment, between each embodiment identical similar portion mutually referring to.
Obviously, it is new without departing from this practicality can to carry out utility model various modification and variations by those skilled in the art
The spirit and scope of type.If in this way, these modifications and variations of the utility model belong to the utility model claims and its
Within the scope of equivalent technologies, then the utility model is also intended to including these modification and variations.
