As briefly mentioned above, conventional UPSs tend to isolate a faulty area or module by means of blowing a fuse in the event of an abnormal current, however, such means have limited protection, and in practice, a single module or local area fault may occur when the entire UPS catches fire. Embodiments of the present disclosure provide a solution for protecting a UPS in which an arc sensor is utilized to detect arc intensity inside the UPS, determine whether the UPS is malfunctioning based on the arc intensity, and in the event of a malfunction, open an input switch and a battery switch external to the UPS, thereby effectively isolating the malfunctioning UPS from other modules.

Some example embodiments of the present disclosure will be described below with reference to the accompanying drawings. Note that in several descriptions of embodiments, certain specific values may be referred to in order to better aid the reader's understanding. These values are exemplary and may vary depending on the particular application and are not intended to limit the scope of the present disclosure in any way.

FIG. 1 illustrates a schematic diagram of an example environment 100 in which embodiments of the present disclosure may be implemented. The environment 100 includes an uninterruptible power supply 110, an input switch 120, an output switch 130, a battery switch 140, and a bypass switch 160 coupled to the uninterruptible power supply 110.

The input switch 120 is connected between an external power source (e.g., mains) and the conversion circuit 190 of the ups 110. With the input switch 120 on, the external power source may provide power to the uninterruptible power supply 110 via the input switch 120. The power provided by the external power source may be converted in the uninterruptible power supply 110. For example, alternating current provided by the external power source may be converted to a desired voltage level via an alternating current-to-direct current (AC/DC) converter and a direct current-to-alternating current (DC/AC) converter in the conversion circuit 190. With the input switch 120 turned off, the ups 110 will be disconnected from the external power source. In some embodiments, the input switch 120 may include a circuit breaker that is capable of switching between open and closed states. In other embodiments, the input switch 120 may comprise other types of isolation switches, all of which fall within the scope of the present disclosure.

The output switch 130 is connected between the output of the ups 110 and a load (not shown). With the output switch 130 on, the uninterruptible power supply 110 may supply power to the load. With the output switch 130 off, the uninterruptible power supply 110 cannot supply power to the load. In some embodiments, the output switch 130 may include a circuit breaker that is capable of switching between open and closed states. In other embodiments, the output switch 130 may comprise other types of isolation switches, all of which fall within the scope of the present disclosure.

The battery switch 140 is connected between the battery 150 and the conversion circuit 190. The battery 150 may be a rechargeable battery. With the external power source in a normal operating state and the input switch 120 and the battery switch 140 turned on, the alternating current provided by the external power source may be converted to a desired voltage level via an alternating current-to-direct current (AC/DC) converter and a direct current-to-direct current (DC/DC) converter in the conversion circuit 190 to charge the battery 150. With the input switch 120 off and the battery switch 140 and the output switch 130 on, the battery 150 may power the load via the conversion circuit 190. For example, the direct current provided by the battery 150 may be converted to alternating current via a direct current-to-direct current (DC/DC) converter and a direct current-to-alternating current (DC/AC) converter in the conversion circuit 190 to power the load. In some embodiments, the battery switch 140 may include a circuit breaker that is capable of switching between open and closed states. In other embodiments, the battery switch 140 may include other types of isolation switches, all of which fall within the scope of the present disclosure.

The bypass switch 160 is connected between the external power source and a bypass branch of the ups 110. With bypass switch 160 on, power provided by the external power source may bypass conversion circuitry 190 in uninterruptible power supply 110 and be provided directly to the load via output switch 130. With bypass switch 160 off, no power is present in the bypass branch of uninterruptible power supply 110. In some embodiments, bypass switch 160 may include a circuit breaker that is capable of switching between open and closed states. In other embodiments, bypass switch 160 may comprise other types of isolation switches, all of which fall within the scope of the present disclosure.

As shown in fig. 1, a controller 170 may be further disposed in the ups 110, and the controller 170 may be connected to the input switch 120, the output switch 130, the battery switch 140, and the bypass switch 160 to control the on-off states of the switches through corresponding control signals.

Uninterruptible power supply 110 typically generates an arc or fire in the event of a fault. If the external power supply or the battery 150 is not cut off in time when the uninterruptible power supply 110 fails, the failure is further upgraded, the module or local area level is expanded to the whole machine or the whole group level, the equipment is burnt, and the fire-fighting start is even initiated in some cases and even the whole building is spread. Embodiments of the present disclosure introduce a means of arc protection by providing an arc protection unit inside the ups 110 that can determine a critical failure at an early stage of the failure of the ups 110. Meanwhile, the uninterruptible power supply 110 converts the arc signal into a control signal of a switch, and turns off an input switch 120 and a battery switch 130 that provide power input to the uninterruptible power supply 110, thereby controlling fault propagation.

As shown in fig. 1, an arc sensor 180 is provided inside the ups 110 to detect the intensity of the arc inside the ups 110. The arc sensor 180 may be configured according to design requirements. For example, one or more arc sensors 180 may be provided separately for different modules of the ups 110, or one or more arc sensors 180 may be provided at strategic locations for the entire ups 110, respectively.

In some embodiments, the uninterruptible power supply 110 may include a modular machine or a modular tower machine. In a modular machine, the uninterruptible power supply 110 includes a plurality of modules connected in parallel to supply power, respectively. In the module machine, each module can be pulled out of the module machine respectively without affecting the work of other modules, and when a single module fails, the other modules can still work normally. The modular tower also includes a plurality of modules, but a single module cannot be easily pulled out of the modular tower. When a single module in a modular tower machine fails, the entire ups 110 needs to be shut down to remove the failed module. In the modular machine and the modular tower machine, a predetermined number of arc sensors 180 may be provided for each module in order to monitor whether the uninterruptible power supply 110 is malfunctioning.

In some embodiments, the ups 110 includes a tower machine that is integral, and any portion failure can affect the operation of the entire ups 110. In such an embodiment, a predetermined number of arc sensors 180 may be provided at different locations within the tower machine in order to monitor whether the ups 110 is malfunctioning.

The intensity of the arc detected by the arc sensor 180 may be communicated to the controller 170. The arc sensor 180 may be connected to the controller 170 by a signal line or a communication line. The controller 170 may determine whether the ups 110 is malfunctioning based at least on the intensity of the arc received. Thus, it is possible to monitor whether a fault occurs in the uninterruptible power supply 110. The controller 170 may be implemented in any suitable manner. The controller 170 may be a controller specially configured to achieve arc protection or may be a controller multiplexed with the ups 110. The controller 170 may be a centralized controller or a plurality of distributed controllers. In some embodiments, the controller 170 may include a Micro Control Unit (MCU). But this is merely exemplary and the controller 170 may also include other types of units such as a processor, a microprocessor, a system on a chip (SoC), etc.

In some embodiments, the uninterruptible power supply 110 or the controller 170 itself may include a storage unit (not shown). The intensity of the arc detected by the arc sensor 180 may be stored in a storage unit. The controller 170 may obtain the arc intensity from the memory unit.

The controller 170 may compare the received arc intensity to a predetermined threshold. In the event that the arc intensity exceeds a predetermined threshold, the controller 170 may determine that the uninterruptible power supply 110 is malfunctioning. In the event that the arc intensity does not exceed the predetermined threshold, the controller 170 may determine that the uninterruptible power supply 110 has not failed.

In response to determining that the uninterruptible power supply 110 is malfunctioning, the controller 170 may generate a first control signal for opening the input switch 120 and the battery switch 140 external to the uninterruptible power supply 110. In the case where the input switch 120 and the battery switch 140 are turned off, the external power source and the power supply from the battery 150 to the uninterruptible power source 110 can be cut off, preventing the fault from further spreading.

In some embodiments, in response to determining that the uninterruptible power supply 110 is malfunctioning, the controller 170 may generate at least one of a second control signal to open the output switch 130 external to the uninterruptible power supply 110 and a third control signal to open the bypass switch 160 external to the uninterruptible power supply 110. By opening the output switch 130 and the bypass switch 160, the spread of the fault can be further prevented, and the safety can be improved.

In some embodiments, it may be determined whether the ups 110 is malfunctioning based on arc intensity and other signals to prevent malfunction of the switch. For example, in the event that the arc intensity exceeds a predetermined threshold, the controller 170 may further determine whether the uninterruptible power supply 110 is malfunctioning in conjunction with at least one of an alarm signal, a current, a temperature, a voltage, and a smoke condition. To this end, at least one of an alarm component, a current sensor, a temperature sensor, a voltage sensor, and a smoke sensor may be disposed within the uninterruptible power supply 110. The alarm component can generate an alarm signal when an abnormality occurs in the operating state of the uninterruptible power supply 110. The current sensor may detect a current of a predetermined component within the uninterruptible power supply 110. The temperature sensor may detect a temperature at a predetermined location within the uninterruptible power supply 110. The voltage sensor may detect a voltage of a predetermined component within the uninterruptible power supply 110. The smoke sensor may detect a smoke condition within the uninterruptible power supply 110.

According to the embodiment of the present disclosure, by detecting the arc intensity inside the uninterruptible power supply 110 using the arc sensor 180, determining whether the uninterruptible power supply 110 fails based on the arc intensity, and turning off a switch outside the uninterruptible power supply 110 in case of failure, the failed uninterruptible power supply 110 can be effectively isolated from other modules, preventing the spread of the failure.

A flowchart of a process 200 for protecting an uninterruptible power supply is described below with reference to fig. 2. Process 200 may be performed by controller 170 shown in fig. 1.

At block 210, an arc intensity detected by an arc sensor 180 disposed inside the uninterruptible power supply 110 is received. As described above, the arc sensor 180 may be provided according to design requirements. For example, one or more arc sensors 180 may be provided separately for different modules of the ups 110, or one or more arc sensors 180 may be provided at strategic locations for the entire ups 110, respectively.

In some embodiments, the uninterruptible power supply 110 may include a modular machine or a modular tower machine. In the modular machine and the modular tower machine, a predetermined number of arc sensors 180 may be provided for each module in the modular machine or the modular tower machine in order to monitor whether the uninterruptible power supply 110 is malfunctioning.

In some embodiments, uninterruptible power supply 110 may include a tower machine. In such an embodiment, a predetermined number of arc sensors 180 may be provided at different locations within the tower machine in order to monitor whether the ups 110 is malfunctioning.

At block 220, it is determined whether the uninterruptible power supply 110 has failed based at least on the arc intensity. In some embodiments, the received arc intensity may be compared to a predetermined threshold. In the event that the arc intensity exceeds a predetermined threshold, it may be determined that the uninterruptible power supply 110 is malfunctioning. In the event that the arc intensity does not exceed a predetermined threshold, it may be determined that the uninterruptible power supply 110 has not failed.

In response to determining that the uninterruptible power supply 110 is malfunctioning, a first control signal is generated to open the input switch 120 and the battery switch 140 external to the uninterruptible power supply 110, at block 230. In the case where the input switch 120 and the battery switch 140 are turned off, the external power source and the power supply from the battery 150 to the uninterruptible power source 110 can be cut off, preventing the fault from further spreading.

In some embodiments, the process 200 further comprises: in response to determining that the uninterruptible power supply 110 is malfunctioning, at least one of a second control signal to open the output switch 130 external to the uninterruptible power supply 110 and a third control signal to open the bypass switch 160 external to the uninterruptible power supply 110 is generated.

In some embodiments, the process 200 further includes receiving at least one of: an alarm signal generated by the alarm assembly when an abnormality occurs in the operating state of the uninterruptible power supply 110, a current of a predetermined component within the uninterruptible power supply 110 detected by the current sensor, a temperature at a predetermined location within the uninterruptible power supply 110 detected by the temperature sensor, a voltage of the predetermined component within the uninterruptible power supply 110 detected by the voltage sensor, and a smoke condition within the uninterruptible power supply 110 detected by the smoke sensor. The process 200 further includes determining whether the uninterruptible power supply 110 has failed based on the arc intensity and at least one of the alarm signals, the current, the temperature, the voltage, and the smoke condition. By determining whether the ups 110 is malfunctioning based on arc intensity and other signals, malfunction of a switch to which the ups 110 is connected can be prevented.

An arc sensor 180 may be disposed inside the ups 110 to detect the intensity of the arc within the ups 110. The processing unit 320 may receive the arc intensity detected by the arc sensor 180 and determine whether the uninterruptible power supply 110 is malfunctioning based at least on the arc intensity. In response to determining that the uninterruptible power supply 110 is malfunctioning, the processing unit 320 may generate a first control signal for opening the input switch 120 and the battery switch 140 external to the uninterruptible power supply 110.

It should be appreciated that the arc sensor 180 may be configured according to design requirements. For example, one or more arc sensors 180 may be provided separately for different modules of the ups 110, or one or more arc sensors 180 may be provided at strategic locations for the entire ups 110, respectively.

In some embodiments, the processing unit 320 may be further configured to: in response to determining that the uninterruptible power supply 110 is malfunctioning, at least one of a second control signal to open the output switch 130 external to the uninterruptible power supply 110 and a third control signal to open the bypass switch 160 external to the uninterruptible power supply 110 is generated.

In some embodiments, the apparatus 300 may further comprise at least one of an alarm component, a current sensor, a temperature sensor, a voltage sensor, and a smoke sensor. The alarm component can generate an alarm signal when an abnormality occurs in the operating state of the uninterruptible power supply 110. The current sensor may detect a current of a predetermined component within the uninterruptible power supply 110. The temperature sensor may detect a temperature at a predetermined location within the uninterruptible power supply 110. The voltage sensor may detect a voltage of a predetermined component within the uninterruptible power supply 110. The smoke sensor may detect a smoke condition within the uninterruptible power supply 110. In such embodiments, the processing unit 30 may determine whether the uninterruptible power supply is malfunctioning based on the arc intensity and at least one of the alert signal, the current, the temperature, the voltage, and the smoke condition to prevent malfunction of the switch.

In some embodiments, the apparatus 300 may further include a storage unit 330. The intensity of the arc light detected by the arc sensor 180 may be stored in the storage unit 330. The controller 170 may obtain the arc intensity from the storage unit 330.
