Description

Technical Field

[0001] The utility model relates to the technical field of power distribution, in particular to a power distribution fuse module. Background Art

[0002] As we all know, electric energy is the main energy and power of modern industrial production. Electric energy is easy to convert from other forms of energy and easy to convert into other forms of energy for use; the transmission and distribution of electric energy is simple and economical, and it is easy to control, adjust and measure, which is conducive to the automation of production processes.

[0003] At present, in industrial control, when powering and controlling instruments, some power supplies are directly connected to instrument equipment through 24V switching power supplies without protection, and some are sent to electrical equipment through fuses. However, the actual construction is cumbersome and error-prone, and there is no intuitive display when a fault occurs. Special tools are required to check the line, which increases the difficulty of maintenance.

[0004] Power supply is the driving force for all controls. If the power supply fails, all related control systems will be out of control, causing serious consequences. At the very least, the equipment will not operate normally. At worst, it will cause control failure, resulting in significant economic losses or even production safety accidents.

[0007] Furthermore, each of the multiple fault detection components includes a fault indicator light and a voltage-limiting resistor connected in series therewith, and the other end of the fault indicator light is fixedly connected to one end of the fuse body, and the other end of the voltage-limiting resistor is fixedly connected to the other end of the fuse body. After the fuse body blows, the electricity is connected to the positive pole of the power output terminal through the fault indicator light and the voltage-limiting resistor.

[0008] Furthermore, the plurality of the positive power output terminals, the negative power output terminals, the power indicator light, the voltage-limiting fuse, the fuse body, the fault indicator light and the voltage-limiting resistor are all fixedly connected to the epoxy resin base plate to prevent the components from loosening.

[0009] Furthermore, the negative electrodes of the plurality of power output terminals are connected in parallel.

[0010] Furthermore, a plurality of the fuse bodies are designed to be connected in parallel, and each fuse body in the parallel circuit can work independently without affecting each other.

[0011] Furthermore, the surfaces of the plurality of the positive power output terminals, the negative power output terminals, the positive power input terminal, the negative power input terminal, the common negative terminal, the power indicator light, the voltage limiting fuse, the fuse body, the fault indicator light and the voltage limiting resistor are all provided with markings for easy viewing.

[0012] Furthermore, the positive poles of the plurality of power output terminals and the negative poles of the adjacent power output terminals together form a complete power output end of the device, which can be connected to an external power meter to facilitate power supply to the external power meter.

[0013] Beneficial effects of the utility model:

[0014] When the utility model is in use, the power distribution fuse module is provided with a fuse body and a fault detection component at the positive pole of each power output. Once a short circuit or a fault occurs at a certain point, the fuse body can be reliably melted, and the relevant signals can be cut off to ensure the normal power supply, so as not to affect other controls and equipment, thereby solving the problem of power failure caused by grounding of the signal line due to lack of protection or installation error, thereby preventing the occurrence of a situation where the entire related control system is completely out of control due to power failure.

[0015] Each output branch of the module is equipped with a fault indicator light to indicate whether the power supply is faulty, making it easier to find the fault point. Through the fault detection module, the error location can be quickly located and the fault point can be found, thereby improving maintenance efficiency and shortening maintenance time.

[0016] The module is small in size, supports installation on a variety of standard guide rails, generates little heat, and can be arranged in a centralized manner. The module is equipped with a sufficient number of negative common terminals, which can save installation space and construction costs. One module has eight outputs and is equipped with two sets of power terminals, which can be wired in cascade and have flexible configuration. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The first wire 3 is fixedly connected to the positive wire 8, and the positive wire 8 is fixedly connected to multiple fuse bodies 10. The multiple fuse bodies 10 are designed to be connected in parallel. The multiple fuse bodies 10 are all connected in parallel with fault detection components. The multiple fault detection components all include a fault indicator light 12 and a voltage-limiting resistor 14 connected in series therewith, and the other end of the fault indicator light 12 is fixedly connected to one end of the fuse body 10, and the other end of the voltage-limiting resistor 14 is fixedly connected to the other end of the fuse body 10.

[0025] The other ends of the plurality of fuse bodies 10 are all fixedly connected to the positive poles 13 of the power output terminals.

[0026] The second wire 9 is fixedly connected to the connecting wire 6, the other end of the connecting wire 6 is fixedly connected to the negative wire 16, the negative wire 16 is fixedly connected to a plurality of negative power output terminals 15, and the plurality of negative power output terminals 15 are designed to be connected in parallel.

[0027] A plurality of positive power output terminal electrodes 13 and adjacent negative power output terminal electrodes 15 together form a complete device power output terminal.
