Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Please refer to fig. 1, the utility model discloses a power is device system of cutting soon, including two way power inlet wires and two way generating lines, two way power inlet wires divide the operation of arranging separately, and at two return circuit power inlet wire switch power cut device soon, be provided with current transformer, voltage transformer and inlet wire switch on every way power inlet wire, two way generating lines segmentation (I mother, II mother), all be provided with voltage transformer on two way generating lines, set up female switch K that allies oneself with between two way generating lines3Each bus is connected with a fan circuit, and the current transformer, the voltage transformer and the incoming line switch are all electrically connected with the power supply quick-cutting device.
A first current transformer TA is arranged on the first power supply inlet wire1A first voltage transformer TV1The first incoming line switch K1。
A second current transformer TA is arranged on the second power supply inlet wire2A second voltage transformer TV2And a second incoming line switch K2。
The first way of bus is connected with the main fan circuit, and the second way of bus is connected with the standby fan circuit.
A third voltage transformer TV is arranged on the first path bus3A fourth voltage transformer TV is arranged on the second bus4。
After a section of incoming line power supply loses power, a proper time is selected, and the bus coupler switch K is quickly closed3And the main ventilator can be quickly powered.
Examples are: when a short-circuit fault occurs at K: first incoming line switch K1Over-current protection action, and the protection device willSending out a pair of contact locking fast switching devices for switching; if the first incoming line switch K1When the operation rejection and overcurrent protection are not operated, the fault current jumps off the first upper-level inlet switch K in a more-level way1Opposite side switch K4At this time, in order to avoid the quick switching device to execute switching, the bus coupler switch K is switched on by mistake3In the fault bus, a large current locking value is set in the fast switching device (the large current locking constant value is generally set as a first incoming switch K)1Overcurrent value) of the first voltage transformer TV, the latch is automatically released after the fault is released, and the detection of the large current is performed through the first voltage transformer TV1And (6) sampling. Under the above conditions, the switching locking and switching failure alarm display is carried out on the background monitoring upper computer, and the field post personnel is reminded to switch to the 6kV II female standby fan according to the operation rules in a few minutes, so that the normal ventilation of the mine is realized.
The power supply fast switching device model: PCS-9655S. The power supply fast switching device can timely judge power failure faults and quickly control and recover the standby power supply, so that the main ventilator is more reliable in operation.
The power supply fast switching device is installed at the inlet wire switch of the ventilator double-loop power supply, when one path of power supply circuit fails and has power failure, the other path of power supply circuit is fast switched and continues to supply power to the power load, uninterrupted power supply of the ventilator is realized, and reliability and continuity of power supply are guaranteed. The automatic switching device is essentially different from a standby automatic switching device in that the automatic switching device has a synchronous capturing function and is short in power supply switching time.
