The device that this embodiment reveals includes casing assembly 1, PLC controlling means 2, relay device 3 and master control set 4, is equipped with an accommodation space in the casing assembly 1, and PLC controlling means 2,

relay device

3 and 4 electricity of master control set are connected and all hold in the accommodation space, and PLC controlling means 2 and relay device 3 are adjacent to be set up.

Specifically, the relay device 3 includes a PLC relay assembly 31, a first intermediate relay assembly 32, and a first terminal X2, which are coupled in this order. The main control device 4 includes a second intermediate relay assembly 41, a plurality of connection terminals 42, and a high voltage vacuum relay assembly 43, which are coupled to each other.

In a specific embodiment, the PLC control device 2 includes a micro circuit breaker assembly 21, a PLC controller 22 and a dc power supply V1 that are coupled in sequence, and the micro circuit breaker assembly 21 includes a first micro circuit breaker Q1, a first micro circuit breaker Q2 and a first micro circuit breaker Q3 that are arranged in parallel, and the two ends of the PLC controller 22 are coupled to a first micro circuit breaker Q3 and a dc power supply V1. The PLC control device 2 is arranged at the upper right corner in the accommodating space.

In one embodiment, the second intermediate relay assembly 41 includes two sets of intermediate relays arranged in parallel, and the number of the intermediate relays in each set is 4. Wherein the first group is REL10, REL11, REL12 and REL13, and the second group is REL20, REL21, REL22 and REL 23. The second intermediate relay assembly 41 is provided below the PLC control device 2.

In one embodiment, the high voltage vacuum relay assembly 43 includes 4 high voltage vacuum relays HVREL20, HVREL21, HVREL22, and HVREL23 arranged in parallel.

The contactor is an electric appliance which utilizes a coil to flow current to generate a magnetic field in industrial electricity to close a contact so as to control a load. The contactor consists of an electromagnetic system (iron core, static iron core and electromagnetic coil) contact system (normally open contact) and an arc-extinguishing device. The principle is that after the electromagnetic coil of the contactor is electrified, a strong magnetic field can be generated, so that the static iron core generates electromagnetic attraction to attract the armature and drive the contact to act: the normally open contact is closed. When the coil is powered off, the electromagnetic attraction disappears, and the armature is released under the action of the release spring to restore the contact: the normally open contact is open.

The original contactor is used for switching on and off an external field loop in a high-voltage switch cabinet, and the normally open contact of the contactor is used for controlling the on and off of the external field loop. This design has no problem in the case of a normal high voltage switch cabinet power supply system. However, when the high-voltage switch cabinet loses power, the contactor is disconnected due to the fact that no power supply is provided, the normally open contact of the contactor is disconnected, the outfield loop is disconnected from the dimmer, light of the outfield loop cannot be started, and operation safety of the navigation aid lighting system is affected.

In view of the disadvantage that the contactor has only normally open contacts, it is therefore necessary to replace the contactor with a device with a normally closed point, and an intermediate relay is very suitable.

The intermediate relay uses the coil to flow current to generate magnetic field, to close the contact, to control the loop. The relay is composed of an electromagnetic system (iron core, static iron core and electromagnetic coil) contact system (normally open and normally closed contacts). The principle is that after the electromagnetic coil of the relay is electrified, a magnetic field can be generated, so that a static iron core generates electromagnetic attraction to attract the armature and drive the contact to act: the normally open contact is closed and the normally closed contact is open. When the coil is powered off, the electromagnetic attraction disappears, and the armature is released under the action of the release spring to restore the contact: the normally open contact is open and the normally closed contact is closed.

Therefore, the normally closed contact is arranged, and the normal power supply of the external field loop can be realized under the condition that the high-voltage switch cabinet is powered off. However, the circuit voltage of the dimmer output is 0 to 45V, and a general intermediate relay cannot satisfy such a high voltage withstand requirement. The inventor of the application determines to select the high-voltage vacuum relay to replace the contactor through a large amount of reference data.

For example, in the present embodiment, the high voltage vacuum relay is selected to have a withstand voltage of 20KV, which is much higher than the highest output voltage of 4545V of the dimmer. Meanwhile, the maximum load current of the high-voltage vacuum relay is 75A, which is also larger than the highest output current of the dimmer, namely 6.6A. Therefore, the high-voltage vacuum relay is very suitable for replacing the existing contactor.

In addition, because the normally closed point of the high-voltage vacuum relay is used, the influence caused by the outage of the high-voltage switch cabinet does not need to be considered, and the UPS is cancelled.

In one embodiment, the second intermediate relay assembly 41 is disposed on top of the high voltage vacuum relay assembly 43.

In one embodiment, the plurality of terminals 42 includes a CMD terminal, a PWR terminal, an LMP terminal, and an ALCS terminal, which are spaced apart in sequence.

In one embodiment, the plurality of terminals 42 are spaced from the high voltage vacuum relay assembly 43 and are positioned above the high voltage vacuum relay assembly 43. A plurality of terminals are provided at intervals on the upper right of the high voltage vacuum relay assembly 43.

In a specific embodiment, the second set of PLC relays is located between the first set of PLC relays and the first terminal X2.

In one embodiment, the master control device 4 is located below the relay device 3. The bottom of the internal receiving space of the high-voltage switching device is also provided with a plurality of terminals 42.

In a specific embodiment, the housing assembly 1 includes a cabinet 11 and a base 12 connected to each other, a control panel 13 and a cabinet door 14 are disposed on the cabinet 11, and a black button head S0 and a switch S01 are disposed on the control panel 13 at intervals.

In a specific embodiment, the height of the cabinet 11 is 1200mm, the height of the base 12 is 100mm, the lengths of the cabinet 11 and the base 12 are both 1000mm, and the widths of the cabinet 11 and the base 12 are both 1000 mm.

In a specific embodiment, the control panel 13 is further provided with a flashing alarm assembly, and the flashing alarm assembly comprises four flashing alarms H1-H4 which are arranged at intervals.

In one embodiment, the control panel 13 is further provided with 4 black spring return buttons S1-S4. The flashing alarm assembly is located between the black button head S0 and the transfer switch S01 and the 4 black spring return buttons S1-S4.

After the high-voltage switching device is transformed, the following effects can be realized: after the high-voltage switch cabinet is powered off, the main dimmer can still supply power to the external field light loop; the use of a UPS is cancelled after the transformation, and a large amount of maintenance cost is saved in the future.
