Problems solved by technology
[0004] This method requires the staff to switch in accurately, and cooperate rigorously in the sequence and time of switching in, but often due to the wrong sequence of switching in and out of individual switches or failure to switch in, the standby self-injection equipment cannot complete the logic according to the program. If the test fails, the test can only be carried out again, which will increase the calibration time, prolong the shutdown time of the standby automatic switching equipment, and reduce the reliability of power supply

Embodiment Construction
[0013] Principle of the present invention and each element realize function as follows:
[0014] 1. Closing switch AN3
[0015] The closing switch AN3 also adopts a reset button. When this button is pressed, point 1 is positively charged. At this time, the action coil of the first self-holding relay ZJ and the action coil of the second self-holding relay KKJ are charged and act at the same time. Their corresponding normal The open contact is closed (the normally open contact is closed, the second light-emitting element HD (red light) is charged and lit), and these corresponding contacts can be introduced into the standby automatic switching device to simulate the closing position of the switch and the hand-closed switch input.
[0016] This function is used to simulate the actual switch manual closing state.
[0017] 2. Protection trip switch AN1
[0018] The protection trip switch AN1 adopts a reset button. When the button is pressed, the contact is closed, and when it is r...

The invention relates to a simulator capable of outputting different combined switch on / off signals for electric power equipment so as to meet demands for equipment detection and the like, in particular to a test switch simulator of automatic throw-in equipment of an emergency power supply. The simulator is characterized by comprising a first lock-up relay (ZJ) and a second lock-up relay (KKJ), wherein, a terminal of a reset coil in the first lock-up relay (ZJ) is connected with the power supply (Vcc) by a protection trip switch (AN1), a terminal of a reset coil in the second lock-up relay (KKJ) is connected with the power supply (Vcc) by an on-off switch (AN2), and another terminal of the reset coil is grounded. The simulator can be switched on / off as a switch, can simulate the action ofa post-on relay (distinguishing manual switching off from protection trip), has simple wire connection, and does not affect the normal operation of the protection device. The simulator is portable, and can reduce failure times of automatic throw-in verification of the emergency power supply.
Description
technical field [0001] The invention relates to a simulation device capable of outputting different combinations of switching value signals for electric equipment to meet the needs of equipment testing and the like, especially a switch simulation device for automatic input of standby power into equipment testing. Background technique [0002] Backup power automatic input (referred to as backup self-injection) equipment can detect that once the main incoming line fails, the main incoming line switch is tripped or the main incoming line switch is accidentally tripped and then tripped again, and the faulty line switch is automatically switched into the hot standby line switch. Quickly restore power. [0003] In order to ensure the reliability of the power supply and ensure the correct operation of the standby automatic switching equipment, it is particularly important to carry out regular inspections on the standby automatic switching equipment. In the inspection process, in o...
