Description

Intelligent detection module of backup protector

Technical Field

The utility model belongs to the technical field of the lightning protection equipment, concretely relates to intelligent detection module of reserve protector.

Background

SPD is surge protector, also called lightning protector, and is an electronic device for providing safety protection for various electronic equipment, instruments and meters and communication lines. In a low-voltage distribution system, when spike current or voltage is suddenly generated in an electric loop or a communication line due to external interference, a surge protector can conduct shunt current, such as overvoltage caused by lightning, in a very short time, so that damage of the surge to other equipment in the loop is avoided.

The SSD is an external disconnector (also called backup protection device) connected in series at the front end of the surge protector. The SSD serving as a backup protection device of a new-generation surge protector has strong breaking capacity and higher surge endurance capacity, and the short-circuit action current of the SSD is far lower than that of the traditional backup protection device under the condition of considering both the breaking capacity and the surge endurance capacity. The low short-circuit current can be effectively cut off, and more precise short-circuit protection is provided for the surge protector. When the SPD is degraded (subjected to lightning current impact or transient overvoltage impact) and the starting voltage is reduced to be lower than the power supply voltage, the power frequency leakage current can be rapidly increased, and when the current is only a few amperes, the SPD thermal tripping mechanism can break a circuit; when the current is more than 10A, the heating, firing and burning speed of the SPD is higher than the heat transfer speed, which means that the SPD is fired when the heat transfer temperature has not reached the tripping temperature, and the external disconnector must disconnect the circuit before causing the SPD to fire to prevent the fire. When the SPD has lightning current, the external disconnector can not be tripped by mistake, so that the lightning protection of the electrical equipment is always in an effective state.

In the current power supply system, to further improve the lightning protection effect and good safety and stability of the circuit, an SPD is generally required to be configured in the circuit, and a special backup protection device, namely an SSD, is required to be configured for normal and stable operation of the SPD. In the prior art, an SPD module which automatically detects a status and transmits a signal in real time is provided, but an external device which detects a status of an SSD is not provided. If the SSD module is redesigned independently to enable the built-in slave state detection function to be built in, the SSD module cannot be adapted to the original SSD module, and the cost is high.

The embodiment is as follows:

the embodiment discloses an intelligent detection module of a backup protector, which is arranged outside an SSD and used as an independent structure to monitor the state of the SSD and the accessed current information.

The SSD module 2 in this embodiment adopts a housing structure with a standard width of 18mm, the housing has two terminals 7 at two ends, a trip mechanism with an electromagnetic pushing structure is provided in the housing, the two terminals 7 and the internal main circuit form a serial connection, and the electromagnetic pushing structure is a parallel connection.

Because the SSD module 2 is connected in series with the SPD module, the normal current in the access circuit cannot pass through the SPD and be grounded, and no current exists on the line in the normal state. When lightning current exists in the access circuit, the resistance of the SPD module is sharply reduced, and at the moment, the lightning current enters the ground wire through the SSD module 2 and the SPD module and is discharged. Because the duration of the lightning current is short, the large current in short time will not cause the electromagnetic driving structure to act.

And once the SPD module is degraded, the leakage current is generated in the continuous leakage current from the SPD module in the access circuit. Once degraded or leaked, the components in the SPD module may be easily ignited. Therefore, the SPD module is protected by the SSD module 2, when continuous power frequency current appears in the circuit, the coil in the electromagnetic pushing structure generates a magnetic field to push the middle armature to act, so that the tripping mechanism is pushed to the disjunction side, and the series circuit is broken.

The SSD module 2 in this embodiment includes at least two independent housing structures, which are directly fastened or separately disposed on the same bent. The intelligent detection module in the embodiment comprises an intelligent module 1 which is also arranged on the bent frame, a port is arranged on the intelligent module 1, information transmission is achieved by connecting the port with external equipment, and communication and power supply can be achieved through the same port.

Due to its snug or close proximity to the terminals 7 of the SSD module 2. And the electric wire connected into the circuit is inserted into the wiring terminal 7 from the port on the side of the SSD module 2 and is pressed and fixed by the wiring terminal 7. Since the access circuit comprises at least two lines, it will only drain through the SSD module 2 in the presence of lightning current. Because the lightning current has a large value, a certain variable magnetic field can be generated, and the coil of the sensor generates current in the magnetic field due to the electromagnetic induction effect. The current signal is amplified and filtered by a processing circuit in the intelligent module 1, so that the current is analyzed to obtain lightning current information.

Preferably, the sensor is in a ring-shaped mutual inductor 11 structure, the inner diameter of the sensor is larger than or equal to the size of a side port of the SSD module 2, the sensor can be directly attached to a port outside a wiring terminal 7 of the SSD module 2 when the sensor is used, and a cable inserted into the wiring terminal 7 passes through the mutual inductor 11, so that current information detection is realized.

Wherein, this sensor one side is equipped with the viscose, directly laminates the port department at the SSD module 2 that corresponds through the viscose. Or, a bolt is adopted, and a hole is formed in the shell of the SSD module 2 and is fixed through the bolt.

Preferably, the sensor is a one-piece structural sensor module 6 comprising a housing and a sensor circuit board 10 disposed within the housing. As shown in fig. 1-4, the specific structure of the sensor module 6 is illustrated.

The mutual inductor 11 is arranged at the corresponding cable interface 9 and keeps a coaxial relation, and a cable penetrating from the cable interface 9 enters the SSD module 2 after passing through the mutual inductor 11 and then is fixedly connected with the wiring terminal 7 in the port.

As can be seen from fig. 4, the housing of the sensor module 6 is formed by two parts that are fastened to each other, wherein one part is provided with protrusions at four corners inside, the sensor circuit board 10 is limited in the housing by the protrusions, and the two parts are fixedly connected by bolts.

And the left side of sensor circuit board 10 board is equipped with connecting terminal 15, is connected with intelligent module 1 fixed on the bent through connecting terminal 15, then reads the detection data summary in the sensor circuit board 10 board by intelligent module 1 and outwards sends.

Furthermore, a terminal is also arranged in the sensor module 6, the electric terminal 12 is a metal conductor, one end of the electric terminal is fixed on the sensor circuit board 10, and the other end of the electric terminal penetrates out of the inner side of the cable interface 9 of the sensor module 6 to form a flat strip-shaped member. The strip-shaped piece is arranged along the edge of the cable interface 9, so that the insertion of an external cable is not blocked, and a certain surface area is provided. When the sensor module 6 is fixed to the SSD module 2, the terminal can protrude from the port of the terminal 7 of the SSD module 2 and be attached to the metal surface inside the terminal 7.

The wiring terminal has certain toughness and deformation, and can only be attached to the wiring terminal 7 when the wiring terminal 7 moves to clamp an inserted cable, so that the connection with an external cable is realized.

Because sensor module 6 all is equipped with a wiring end on every cable interface 9 respectively, then can be connected with external circuit alone through the wiring end to when no electric current passes through SSD module 2, also can produce the electric energy on sensor circuit board 10 board and supply for intelligent module 1. Meanwhile, other equipment can be powered through the cable.

Preferably, the sensor module 6 is an independent structure and can be directly fixed outside the SSD module 2 by means of adhesive or magnetic attraction. Or the sensor module 2 is matched with the SSD module and detachably connected with the sensor module 6 by arranging structures such as binding bands or buckles.

Or, the sensor module 6 itself is not directly connected to the SSD module 2, as shown in fig. 5 to 7, a buckle is disposed on one side of the sensor module 6, and a bayonet for accommodating the buckle and forming a bayonet fixing is disposed on one side of the smart module 1.

The other signal port 5 is connected with an external system through a cable or other equipment, so that the collected real-time information can be transmitted to the external system for feedback and data reading, and data can be directly written or program setting can be changed when needed through a remote system.

In this embodiment, the signal port 5 uses a 485 bus, but the scheme is not limited to this, and a communication bus may also be used.

Preferably, a trip detection lever 14 is further provided in the smart module 1, and the trip detection lever 14 is freely rotatable in the smart module 1 and has an extended end extending from a side of the smart module 1 close to the SSD module 2. The extension end has a hexagonal-like end portion, can be inserted into the axis of a shift lever 8 of the SSD, and is in transmission connection with the shift lever 8.

Because the external shifting rod 8 immediately rotates when the tripping mechanism inside the SSD module 2 operates, the tripping detection rod 14 in transmission connection with the shifting rod 8 synchronously rotates at the moment. The part of the trip detection rod 14 inside the intelligent module 1 is provided with a disk-shaped expansion end, and the disk surface of the expansion end is provided with at least one magnet 17. And a corresponding hall sensor 16 is arranged on the control circuit board 13 near the tripping detection rod 14, and in an initial state, a magnet 17 on the disk surface of the tripping detection rod 14 is just aligned with the hall sensor 16 or is not in the detection range of the hall sensor 16. Then, when the position of the magnet 17 is changed, the data detected by the hall sensor 16 changes suddenly, and the data is fed back and transmitted as the information of the SSD module 2 tripping.

The trip detection lever 14 in this embodiment is provided with two magnets 17, and the control circuit board 13 is provided with two corresponding hall sensors 16. In an initial state, the two magnets 17 are both located at the position of the hall sensor 16, the hall sensor 16 can detect the existence of the magnets 17 at this time, and after the positions of the two magnets 17 are changed, the two magnets 17 are far away from the hall sensor 16, and a detection value is abruptly changed at this time and is output as a feedback signal. Meanwhile, the detection stability can be improved due to the arrangement of at least two magnets 17.
