Description

Technical Field

[0001] The present invention relates to the field of power supply equipment, and particularly to a UPS power supply with a leakage protection function. Background Art

[0002] A UPS power supply is a device that uses a battery or other power reserve device to provide stable electrical energy during a power interruption or voltage fluctuation. In the event of a power outage, low voltage, or voltage fluctuation, the UPS power supply can immediately provide backup power to prevent data loss or hardware damage to equipment. For some critical equipment (such as medical equipment, communication equipment, etc.), the UPS can ensure that it can still operate normally during a power outage and guarantee its continuous service. Most UPS devices also have overload and short-circuit protection functions to ensure the safety of the equipment. The UPS power supply plays an important role in modern information and power management and is widely used in multiple fields such as data centers, hospitals, financial institutions, industrial control, and households.

[0003] Existing UPS power supplies with a leakage protection function usually consist of a protective box, a battery pack, and a charge and discharge control system. The protective box is used to protect the battery pack and circuit control components. The battery pack is connected in series to store electrical energy for backup. The charge and discharge control system usually includes a power input interface, a power output interface, a controller, an inverter, and a circuit breaker, etc. The controller is used to control the input of mains power and the output of battery power to ensure automatic switching to battery power supply when the mains power is interrupted. The inverter converts alternating current into direct current to charge the battery under normal mains power conditions, and converts the direct current in the battery into alternating current when the mains power is interrupted for use by the load. The circuit breaker is used to detect faults in the circuit and automatically cut off the circuit to prevent equipment damage or safety accidents such as fires.

[0004] During the use of existing UPS power supplies with a leakage protection function, since the battery pack is installed tightly and the battery pack needs to be charged and discharged frequently during use to avoid a decrease in battery energy storage performance, a large amount of heat is generated during the charge and discharge process of the battery pack, resulting in frequent temperature rises and falls inside the protective box. At the same time, there are significant differences in ambient temperature due to seasonal changes. The low temperature environment in winter affects battery activity, and abnormal temperature changes may accelerate the aging of the circuit, thereby affecting the service life of the UPS power supply and even its safety. Summary of the Invention

[0005] Based on this, in view of the problems in the prior art, it is necessary to provide a UPS power supply with a leakage protection function.

The condenser is fixedly arranged on the side wall of the protective box. The compressor is fixedly arranged on the side wall of the protective box near the condenser. A third notch for the fan to be inserted is formed on the side wall of the protective box. A temperature sensor is fixedly arranged on the inner top of the protective box.

[0008] Further, a pipeline is arranged on the side wall of the condenser and is connected to the compressor in communication. The condensation pipe is inserted on the side wall of the protective box, and the two ends of the condensation pipe are sequentially connected to the condenser and the compressor in communication. The condensation pipe is arranged in an S shape on the side wall of the fan. The heating wires are symmetrically and fixedly arranged on the side wall of the fan near the condensation pipe. The inside of the condensation pipe is filled with a coolant.

[0009] Further, second partition boards are fixedly arranged on the top ends of the first partition boards, and inner supports are fixedly arranged on the inner side walls of the second partition boards. The inner supports are all in a wavy shape, and two heat conducting pads are fixedly arranged on the side walls of the inner supports. The other sides of the heat conducting pads support on the side walls of the battery packs.

[0010] Further, the battery packs are connected in series in sequence, and the input interface, the output interface, the battery packs, the inverter, and the circuit breaker protector are coupled to the controller in sequence.

After the battery packs are connected in series, they are then coupled to the controller. Wires are arranged at the ends of the input interface and coupled to the commercial power, and wires are arranged at the ends of the output interface and coupled to the circuit of the protection device.

Then starting the fan can blow cold air into the protection box, and the cold air can flow between the battery packs, so as to accelerate the cooling inside the protection box. When the heating wire and the fan are started, they can heat the inside of the protection box.

[0020] The beneficial effects of the present invention compared with the prior art are:

[0021] First, a UPS power supply with leakage protection function in the present invention cooperates with a protection box, a constant temperature system, a limit assembly, a battery pack and a temperature sensor. The constant temperature system includes a condenser, a compressor, a fan, a condenser tube and a heating wire. The temperature sensor can accelerate the cooling of the inside of the protection box by cooperating with the compressor, the fan and the condenser tube. The temperature sensor can increase the temperature inside the protection box by working with the compressor and the heating wire, thereby ensuring that the inside of the protection box is constant, thereby reducing line damage and increasing the service life of the equipment;

[0022] Secondly, a UPS power supply with leakage protection function in the present invention is provided with a second partition, an inner support and a thermal pad. The second partition is hollow inside to facilitate air circulation, the inner support is wavy to improve the stability of the second partition support, and the thermal pad improves the stability of the battery pack and the second partition, thereby improving the heat transfer efficiency of the battery pack;

[0023] Thirdly, a UPS power supply with leakage protection function in the present invention is provided with a pressure gauge and a warning light. The pressure gauge can detect the internal pressure of the condenser in real time.

At the four corner positions of the bottom end of the protective box (1), bases (13) are fixedly provided. Protrusions (14) are clamped in the middle of the bases (13).

9. A UPS power supply with a leakage protection function according to claim 1, characterized in that: A second dust-proof net (7) is clamped on the side wall of the protective box (1) away from the first dust-proof net (404). A handle (5) is provided at the top end of the protective box (1). The internal dimensions of the second clamping groove (6) are adapted to the external dimensions of the second dust-proof net (7).

10. A UPS power supply with a leakage protection function, adopting a UPS power supply with a leakage protection function as described in any one of claims 1-9, characterized in that, Including the following steps: S1: Wiring and grid connection. The battery packs (16) are sequentially clamped on the surface of the support plate (1502). The first partition plates (1503) and the second partition plates (1509) support and limit. After the battery packs (16) are connected in series in sequence, they are coupled to the controller (21). Wires are arranged at the ends of the input interface (3) to be coupled to the mains electricity, and wires are arranged at the ends of the output interface (11) to be coupled to the circuit of the protection device. S2: Charging and discharging. Close the master control switch (9) to connect the device to the mains electricity. The controller (21) controls the inverter (18) to convert the alternating current output by the mains electricity into direct current and store it inside the battery pack (16) for charging. When the mains electricity is cut off, the battery pack (16) supplies power to the controller (21), so that the controller (21) is driven reversely to convert the direct current stored inside the battery pack (16) into alternating current and release it for emergency use of the device. S3: Constant temperature control. The temperature sensor (20) is used to sense the temperature change inside the protection box (1). The temperature sensor (20) controls the start and stop of the compressor (402), the fan (403) and the heating wire (410) in a linked manner. Starting the compressor (402) can make the coolant inside the driving condenser pipe (406) enter the condenser (401) for heat dissipation and cooling, and then flow back into the condenser pipe (406). Then starting the fan (403) can blow cold air into the interior of the protection box (1). The cold air can flow between the battery packs (16), thereby accelerating the cooling inside the protection box (1). When the heating wire (410) and the fan (403) are started, they can heat the interior of the protection box (1).
