It connects to realize human-computer interaction.That is, when program-controlled terminal 1 is judged not meeting unlocking condition according to the information of reading, by aobvious
Show and the condition for being not up to unlocking is shown, in order to which operating personnel operate.
Preferably, program-controlled terminal 1 is equipped with data-interface, and the data-interface with computer or RAM card connecting in turn
Carry out the setting of the control logic of program-controlled terminal 1.Since different equipment is deposited with different type, the other equipment of different number
It is being latched, therefore the condition of the judgement locking of each program-controlled terminal 1 is different, it is therefore desirable to the program-controlled terminal 1 of distinct device
Different configurations is carried out, therefore is provided with data-interface.
The utility model prevents the principle of maloperation and application method as follows：
By taking single loop feeder line as an example：
According to safety regulation for operations, close circuit breaker needs first to be closed corresponding disconnecting switch, in close circuit breaker, disconnects
When breaker, first cut-off breaker is needed to disconnect disconnecting switch, accordingly, by taking close circuit breaker as an example：
Solution pintle hook lock 2 is placed in the program-controlled terminal 1 of disconnecting switch first, is unlocked, after the completion of isolator operation,
Inside information and location status information the write-in solution pintle hook lock 2 that disconnecting switch closed procedure is completed.It is placed on pintle hook lock 2 will be solved
In the program-controlled terminal 1 of breaker, the program-controlled terminal 1 of breaker reads the information inside solution pintle hook lock 2, if the information obtained for every
It leaves and closes closed, the then locking of contact breaker closed procedure, be not closed if the information obtained is disconnecting switch,
Keep the locking of circuit breaker closing closing operation.Realize the closed procedure of breaker or the mode of opening operation：By program-controlled terminal 1
The node ship of control signal output module 13 concatenates in circuit-breaker switching on-off operation circuit, even if locking node disconnects, operation
Circuit can not operate.The node control electromagnetic lock of control signal output module 13 can be utilized for the locking of disconnecting switch, then
