Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The following detailed description of embodiments of the utility model refers to the accompanying drawings.

Fig. 1 is a schematic diagram schematically illustrating a farm room circuitry 100 according to an embodiment of the present invention.

As shown in fig. 1, the power supply of the machine room is obtained from the main power box, so as to obtain power supplies L1, L2, L3 and N, the power supply is connected with the breaker 101 through an incoming line, and the breaker 101 is connected with the power distribution cabinet of the machine room through an outgoing line, so as to supply power to each electric device in the machine room. An intelligent network cabinet, a server cabinet, illumination, an air valve, an air conditioner socket, a network exchange box and the like are generally required to be arranged in the current farm machine room. An Uninterruptible Power Supply (UPS) needs to be configured in the cabinet to realize uninterrupted Power Supply. Sockets or air switches can be reserved for the cabinets in the machine rooms directly for UPS power supply use, and conventional cabinet sockets, service cabinet switches and the like are reserved in each machine room. A computer room UPS power supply is an uninterruptible power supply that can provide uninterrupted power supply to computers/servers, storage devices, and network devices during a power outage using energy storage devices. A PDU ("Power Distribution Unit"), which is a kind of Power Distribution Unit and can also be called a socket bank, is installed on a cabinet. After the mains supply supplies power to the UPS host, the UPS outputs power to the UPS distribution box, the UPS distribution box distributes power to each cabinet PDU, and the PDU supplies power to the equipment. The PDU distributes the output current from the UPS to the tail end power distribution equipment of each IT equipment, and is key equipment for connecting basic facilities such as power supply and the like and normally operating all equipment in an IT system and an associated machine room.

When the UPS is used, circuits for resisting surge and harmonic interference are arranged on a live wire, a zero line and a ground wire of the UPS. The anti-harmonic, anti-surge, etc. circuits have capacitors (or other elements) connected from the phase line end to the ground (but not the neutral) end, thereby generating leakage current, which may cause the leakage protection switch to operate. Thus, the UPS itself may be considered a leakage device.

In practical operation, in a machine room power supply line, a circuit breaker needs to be arranged to realize the connection or disconnection of the power supply line. However, according to the electrical design specifications, in the design of farms, houses, and the like, in addition to the air-conditioning power outlet, other power circuits should be provided with an earth leakage protection device, such as the breaker 104 with earth leakage protection function shown in fig. 1.

However, due to the particularity of the UPS power supply in the machine room, leakage current may be generated during the use process, which may easily cause the leakage protection switch to operate, and then the circuit is powered off, and the UPS is no longer charged. Therefore, a circuit breaker with a leakage protection function, such as the circuit breaker 105 without the leakage protection function shown in fig. 1, is not generally provided in the UPS power supply circuit. However, when the sockets or circuit breakers of the intelligent network cabinet and the server cabinet are low, and people may touch the sockets or circuit breakers, if leakage protection measures are not provided, accidents of electric shock of workers may occur.

In view of this, the system for power utilization protection is arranged on the circuit breaker 101 at the front end of the machine room, so that the reliable monitoring of the electricity leakage and power failure conditions of the machine room is realized, and the more effective safety protection of the power utilization of the machine room is realized. Specifically, in the utility model, the leakage protection unit 102 and the power-off protection unit 103 are arranged on the incoming line and the outgoing line of the circuit breaker, so that the monitoring on the electricity safety is realized. The earth leakage protection unit 102 may disconnect the circuit breaker when detecting that an earth leakage occurs, and the power failure protection unit 103 may alarm when detecting that a commercial power is disconnected, thereby implementing an effective protection process. The system can be applied to various lines where the circuit breakers with the electric leakage protection devices and the circuit breakers without the electric leakage protection devices are located, so that the system for protecting the electricity for the farm machine room has good usability.

The specific components of the earth leakage protection unit and the power-off protection unit of the present invention will be described in detail below. Fig. 2 is a schematic diagram schematically showing a composition structure of a leakage protection unit 200 according to an embodiment of the present invention. It is to be understood that the earth leakage protection unit 200 shown in fig. 2 is one implementation of the earth leakage protection unit 102 shown in fig. 1, and it may be implemented in the structure shown in fig. 1, so that what is described with respect to fig. 1 also applies to fig. 2.

As shown in fig. 2, the earth leakage protection unit 200 may include a sampling coil 201 and a first controller 202, wherein the sampling coil 201 is sleeved on the incoming line for inducing a residual current to detect whether an earth leakage occurs. The first controller 202 is connected to a circuit breaker for opening the circuit breaker upon detection of occurrence of an electric leakage. In some embodiments, the sampling coil can be sleeved outside the incoming cable so as to induce residual current through the electromagnetic induction principle and realize the monitoring of leakage current. The sampling coil may be, for example, a residual current sensor. The first controller may be connected to the exciting coil in the circuit breaker, so as to control the circuit breaker by controlling the current in the exciting coil.

In some embodiments, the earth leakage protection unit 200 may further comprise a first current transformer 203. The first current transformer 203 is connected to the incoming or outgoing line for detecting the current flowing in the circuit breaker. The first controller 202 may be connected to a first current transformer 203 for obtaining a three-phase current flowing in the circuit breaker. The condition of a power supply line can be known in real time by monitoring the current in the line where the circuit breaker is located.

In some embodiments, the earth leakage protection unit 200 may further include a temperature sensor 204. A temperature sensor 204 is provided at the cable at the load end of the circuit breaker and may be used to detect the cable temperature. The first controller 202 is connected to a temperature sensor 204 for monitoring cable temperature information. By monitoring the temperature in the cable, the safety accidents such as fire disasters and the like caused by short circuit, virtual connection, aging and the like can be effectively prevented.

In some embodiments, the earth leakage protection unit 200 may further include an earth leakage warning circuit 205. The leakage alarm circuit 205 is connected to the first controller 202, and can alarm when a leakage fault occurs. Specifically, a corresponding alarm set value may be set in the first controller, and when each detected parameter exceeds the alarm set value, an alarm signal may be sent out, so that a worker may process the parameter in time.

Further, the earth leakage protection unit 200 may further include a first communication circuit 206. The first communication circuit 206 is connected to the first controller 202 for communicating with an external device by wire or wirelessly to upload detected information. For example, the detected information can be uploaded to the cloud platform through the first communication circuit, and the cloud platform can trigger message reminding after receiving the hidden danger information, so that a user can timely perform field processing and troubleshoot problems after receiving the reminding, and electrical accidents are effectively prevented.

Fig. 3 is a schematic diagram schematically showing an implementation of leakage monitoring by a leakage protection unit to which an embodiment of the present invention is applied. It will be appreciated that the earth leakage protection unit shown in fig. 3 is one implementation of the earth leakage protection unit 102 shown in fig. 1, and it may be implemented in the structure shown in fig. 1, and therefore what is described with respect to fig. 1 also applies to fig. 3.

Fig. 3 shows the arrangement of the earth leakage protection unit in the present invention on the front-end main breaker. The leakage protection unit can be configured on the front-end main circuit breaker, and A, B, C, N phase wires of an incoming line of the main circuit breaker all penetrate through the residual current transformer to detect residual current. The current transformers TAa, TAb and TAc are respectively sleeved on the three wires of the lower end A, B, C of the main circuit breaker and used for measuring A, B, C three-phase current. The temperature sensor probe corresponds to A, B, C, N phases according to yellow, green, red and black, and is bound at the load end of the circuit breaker by an electric insulation flame-retardant adhesive tape for monitoring the temperature of the cable, so that the electric accidents caused by short circuit, virtual connection and aging can be solved.

Further, a voltage detection circuit 301 can be further arranged in the leakage protection unit to monitor the voltage in the line, so that more comprehensive power utilization safety protection is realized.

Fig. 4 is a schematic diagram schematically illustrating the structure of a power-off protection unit 400 according to an embodiment of the present invention. It is to be understood that the power down protection unit 400 shown in fig. 4 is one implementation of the leakage protection unit 103 shown in fig. 1, and it can be implemented in the structure shown in fig. 1, so that what is described with respect to fig. 1 also applies to fig. 4.

As shown in fig. 4, the system for protecting farm machinery room from electricity in the present invention further includes a power-off protection unit 400. The power down protection unit 400 may include a power down detection circuit 401, a second controller 402, and a power down alarm 403. The power-off detection circuit 401 may be connected to a breaker outlet, and the second controller 402 is connected to the power-off detection circuit 401 and the power-off alarm 403 so as to alarm when a commercial power cut-off is detected.

In some embodiments, the power down detection circuit 401 may include various forms of arrangements. In a first arrangement, the outage detection circuit 401 may include a second current transformer. The second current transformer is connected with the outgoing line and can be used for detecting whether power failure occurs or not. In a second arrangement, the power-off detection circuit comprises an electromagnetic relay, an electromagnetic coil of the electromagnetic relay is connected with an outgoing line, and a contact of the electromagnetic relay is connected with an input end of a power-off alarm and is used for controlling the power-off alarm to give an alarm when the power-off is detected through the electromagnetic coil. For example, when the power failure occurs, the electromagnetic coil of the electromagnetic relay loses power, and the contact coupled with the electromagnetic coil is closed, so that the alarm device is connected with a direct current power supply, and the alarm is automatically realized.

In some embodiments, the power outage alarm 403 may include an audible alarm circuit. The second controller is connected with the sound alarm circuit and is used for controlling the sound alarm circuit to send out an alarm signal when power failure occurs. For example, the audible alarm circuit may include a buzzer. The buzzer is arranged at the courtyard of the living area of the farm, and the input end of the buzzer is connected with the output end of the second controller and used for carrying out sound alarm according to the output of the second controller. Further, the power-off alarm may further include an optical alarm circuit, and the optical alarm circuit may light up an indicator lamp to perform an alarm operation when the occurrence of the power-off condition is detected.

Further, the power down protection unit of the present invention may further include a second communication circuit 404. The second communication circuit 404 is connected to the second controller 402 for transmitting the alarm information to the external device by wire or wirelessly.

The way of realizing power failure detection and alarm control by using an electromagnetic relay is shown in fig. 5. Specifically, the power line 501 of the power-off alarm in the power-off protection unit may be connected to the lower end of the UPS power supply in the cabinet, so that the power-off alarm may still be powered when a power outage occurs. For example, the power-off alarm 403 may employ a USR alarm device. When the electromagnetic coil arranged at the outlet of the circuit breaker detects that power failure occurs, the electromagnetic coil KM1 loses power, and the corresponding contact is closed, so that the USR alarm device is electrified and conducted, and can directly give an alarm. In order to prevent the manager from missing the alarm information when leaving the machine room, the output end of the USR alarm device can be connected with the audible and visual alarm device 502 arranged at the courtyard of the living area, so that the manager can still quickly receive the alarm information when leaving the machine room.

Furthermore, the USR device can also realize the communication process with external equipment through a communication interface, thereby realizing remote alarm operation. For example, a call can be made to a smart phone of a worker bound to the USR alarm device to realize timely alarm.
