Description

Technical Field

[0001] This application relates to the field of low-voltage electrical technology, and more specifically, to a power transfer switching system. Background Technology

[0002] With the rapid development of smart grid construction in my country, critical power supply locations such as airports, high-rise buildings, and high-speed railways, where power outages are unacceptable, are facing increasingly stringent requirements for the reliability of continuous power supply. To ensure the continuity of power supply to loads, multi-source power conversion systems are widely used in the field of continuous power supply. However, due to their complex and chaotic circuit connections, numerous adapters, and dispersed locations, multi-source power conversion systems suffer from problems such as easy wiring errors and unstable voltage drops caused by excessively long interlocking distances between circuit breakers.

[0003] In related technologies, a multi-power conversion system typically consists of a controller, multiple adapters, multiple power supplies, and power circuit breakers. Each adapter and each circuit breaker is connected via a cable, and the controller is connected to each adapter via a network interface. The controller directly exchanges real-time data with each adapter via the network interface to complete the multi-power management function.

[0004] However, when constructing a multi-power conversion system based on related technologies, there is a problem of multiple and decentralized adapters. This will result in excessively long interlocking distances between multiple circuit breakers and the risk of control failure of the multi-power conversion system due to unstable voltage drop.

[0045] Currently, multi-power conversion systems typically consist of a controller, multiple adapters, multiple power supplies, and multiple circuit breakers. Each adapter corresponds one-to-one with a circuit breaker, and each adapter is connected to a circuit breaker via a cable. The controller connects to each adapter via a network interface, directly exchanging data with each adapter to achieve multi-power management. However, this approach suffers from an excessive number of adapters and their lack of centralization. This results in excessively long interlocking distances and round-trip distances between multiple circuit breakers, leading to unstable voltage drops in the multi-power conversion system and ultimately increasing the risk of control failure.

[0046] To address this, this application provides a power transfer switch system comprising a controller, an adapter, multiple power circuit breakers, multiple bus circuit breakers, and prefabricated wiring harnesses. The adapter connects to the control terminals of each power circuit breaker and each bus circuit breaker via the prefabricated control wiring harnesses, and is also connected to the controller via the prefabricated wiring harnesses. The adapter integrates both power and bus information into a single unit via the prefabricated wiring harnesses, and integrates and expands multiple power and bus information signals through internal circuit breakers or contactors, significantly reducing the interlocking distance between circuit breakers and making the interlocking signals between circuit breakers more stable. This achieves the effect of integrating and expanding multiple signals, reducing the interlocking distance between circuit breakers, making the interlocking signals more stable, and improving the safety and reliability of the power transfer switch system.

[0047] The power transfer switch system provided in the embodiments of this application will be explained in detail below with reference to the accompanying drawings.

[0048] Figure 1 A power transfer switching system provided in this application, see [link to relevant documentation]. Figure 1 The power transfer switch system 10 provided in this application includes: a controller 101, an adapter 102, at least one power circuit breaker 103, at least one bus circuit breaker 104, and a prefabricated wiring harness.

[0049] The control terminals of each power circuit breaker 103 and each bus circuit breaker 104 are connected to the adapter 102 via prefabricated wiring harnesses. The adapter samples the power information of each power circuit breaker and the bus information of each bus circuit breaker through the prefabricated wiring harnesses. The adapter also controls the on / off state of each power circuit breaker and each bus circuit breaker through the prefabricated wiring harnesses.

[0050] Optionally, the power circuit breaker 103 is used to provide electrical protection for the power supply in the power transfer switching system 10. When the circuit is abnormal, the power circuit breaker 103 can only disconnect the circuit branch associated with itself. The bus circuit breaker 104 is used to protect the electrical system of the power transfer switching system 10. The bus circuit breaker 104 is usually deployed at the outgoing line or load side of the electrical system, which is equivalent to a bus switch.

[0051] Optionally, the prefabricated wiring harness is a wiring harness issued by the adapter 102. The prefabricated wiring harness can be implemented by integrating multiple wiring harnesses or can be regarded as a single wiring harness. The adapter 102 is connected to the control terminals of each power circuit breaker 103 and each bus circuit breaker 104 via the prefabricated wiring harness. The adapter 102 can not only control the on / off state of each power circuit breaker 103 and each bus circuit breaker 104 through the prefabricated wiring harness, but also obtain power information related to the power supply connected to each power circuit breaker 103 from the power circuit breaker 103 through the prefabricated wiring harness. The power information includes electrical parameters such as voltage, current, and power of the power supply. The adapter 102 can also obtain the current operating status of each power circuit breaker 103 and each bus circuit breaker 104 through the prefabricated wiring harness. The current operating status includes the circuit breaker's open state, closed state, and fault state.

[0052] Optionally, the power information obtained by the adapter 102 from each power circuit breaker 103 via the prefabricated wiring harness includes: the current operating voltage, current operating current, current operating power of the power supply corresponding to the power circuit breaker 103, as well as the opening, closing, and fault information of the power circuit breaker; the bus information obtained by the adapter 102 from each bus circuit breaker 104 via the prefabricated wiring harness includes: the operating voltage of the bus, the current flowing through it, and the opening, closing, and fault information of the bus circuit breaker.

[0053] The adapter 102 is connected to the controller 101 via a pre-fabricated wiring harness, and the adapter 102 transmits signals to the controller via the pre-fabricated wiring harness.

[0054] Optionally, the controller 101 is connected to the adapter 102 via a prefabricated wiring harness, and the controller 101 transmits signals to the adapter 102 through the prefabricated wiring harness. Specifically, the controller 101 acquires the operating status of the power circuit breaker 103, the operating status of the bus circuit breaker 104, and the power parameters of the power supplies connected to each power circuit breaker 103, sampled by the adapter 102, through the prefabricated wiring harness. Simultaneously, the controller 101 sends corresponding control commands to the adapter 102 through the prefabricated wiring harness, and sends mechanical interlocking logic signals adapted to the control commands to the adapter 102 via the prefabricated wiring harness. Under the action of the control commands and interlocking logic signals sent by the controller 101, the adapter 102 controls the open or closed states of each power circuit breaker 103 and each bus circuit breaker 104, so that the power transfer switching system 10 can stably and reliably provide power supply voltage to the external load.

[0055] In this embodiment, a power transfer switch system is composed of a controller, an adapter, multiple power circuit breakers, multiple bus circuit breakers, and prefabricated wiring harnesses. The adapter connects to the control terminals of each power circuit breaker and each bus circuit breaker via the prefabricated wiring harnesses, and the controller connects to the adapter via the prefabricated wiring harnesses. The adapter samples power information from each power circuit breaker and bus information from each bus circuit breaker via the prefabricated wiring harnesses. It also controls the on / off states of each power circuit breaker and bus circuit breaker via the prefabricated wiring harnesses and transmits signals to the controller via the prefabricated wiring harnesses. The adapter centralizes multiple power and bus information streams via the prefabricated wiring harnesses and implements mechanical interlocking of the circuit breakers, effectively avoiding the unstable interlocking defects caused by distributed long-distance voltage drops. This achieves the integration and expansion of multiple signals, reduces the interlocking distance between circuit breakers, makes the interlocking signals more stable, and improves the safety and reliability of the power transfer switch system.

[0056] In one alternative implementation, see [link to implementation details]. Figure 2 The adapter 102 in the power transfer switch system 10 provided in this application embodiment includes a relay or contactor. The prefabricated wiring harness includes multiple control wiring harnesses 105.

It also performs one-to-many information expansion on multiple power information and multiple bus information via relays or contactors, and centrally performs mechanical and electrical interlocking on multiple power information and multiple bus information.

[0057] Optionally, the adapter 102 is equipped with relays or contactors. The adapter 102 extends the information of multiple power sources and multiple busbars through the built-in relays or contactors, and centrally implements mechanical and electrical safety interlocking for multiple power sources and multiple busbars. This can effectively avoid the defects of unstable interlocking caused by distributed long-distance voltage drop.

[0058] Optionally, the power information obtained by the adapter 102 from each power circuit breaker 103 via the control wiring harness includes: the current operating voltage, current operating current, current operating power of the power supply corresponding to the power circuit breaker 103, as well as the opening, closing, and fault information of the power circuit breaker; the bus information obtained by the adapter 102 from each bus circuit breaker 104 via the control wiring harness includes: the operating voltage of the bus, the current flowing through it, the opening, closing, and fault information of the bus circuit breaker.

[0059] Optionally, the adapter 102 achieves interlocking and integration of power supply information and bus information via multiple control harnesses 105. The adapter 102 also achieves interlocking control of multiple power circuit breakers 103 and multiple bus circuit breakers 104 via multiple control harnesses 105.

[0060] For example, when only one power supply is operating normally among the multiple power supply information obtained by the adapter 102 from each power circuit breaker 103 via multiple control harnesses 105, the adapter 102 supplies power to multiple circuit branches such as the controller and the load connected to the bus based on this power supply, thereby realizing the information expansion of one output to multiple circuits.

[0082] The power module 108 and the adapter 102 are connected by a cable.

[0083] Optionally, power module 108 refers to a combination of multiple power supplies that can be flexibly switched in power conversion switching system 10. Power module 108 can be independent of adapter 102. When power module 108 is an independent module, power module 108 is connected to adapter 102 through a cable. Adapter 102 selects the power supply in power module 108 based on control commands and interlocking logic signals issued by controller 101.

[0094] Optionally, the bus circuit breaker 104 is used to control the on / off state of the bus in the power transfer switching system 10, where the bus serves as the main power supply circuit for the power transfer switching system 10. For example, if there is a power supply abnormality in the power supply 1 in the power transfer switching system 10, the power circuit breaker 1 cuts off the power supply to the power supply 1. Simultaneously, the bus circuit breaker 1 disconnects the bus associated with the power supply circuit of the power supply 1, thereby improving the power supply reliability of the power transfer switching system 10. This application does not specifically limit this aspect.
