[0092] The following embodiments given in conjunction with the accompanying drawings further illustrate the specific implementation manners of the intelligent measurement switch with multi-phase independent breaking of the present utility model. The intelligent measurement switch with multi-phase independent breaking of the present utility model is not limited to the descriptions of the following embodiments.

[0093] As Figure 1 shown, the intelligent measurement switch with multi-phase independent breaking of this embodiment includes a housing 1 and three phase pole units arranged side by side in the housing 1. Each phase pole unit includes two terminal connectors arranged at both ends, as well as an arc extinguishing chamber, a static contact, a moving contact, an operating mechanism, and a release arranged between the two terminal connectors. The operating mechanism is connected to the moving contact. Each operating mechanism of the phase pole unit has a handle 10 extending outside the housing 1. The handle 10 can drive the moving contact of the corresponding phase pole unit to contact and separate from the static contact through the operating mechanism. The operating mechanism includes an energy storage mechanism, and the energy storage mechanism is locked in the energy storage state when the moving contact contacts the static contact. The operating mechanism generally includes a locking catch and a tripping catch that are latched together. The link structure (four-bar link or five-bar link) formed when the locking catch and the tripping catch are latched together can drive the moving contact to swing. When the moving contact contacts the static contact, the spring serving as the energy storage mechanism is locked in the energy storage state. When the locking catch is pushed to release the latching cooperation between the locking catch and the tripping catch, the operating mechanism trips, and the unlocked energy storage mechanism releases energy to drive the moving contact to separate from the static contact, achieving fault protection. The release is generally an electromagnetic release, which can trigger the drive to release the latching cooperation between the locking catch and the tripping catch after being powered on.

[0094] The housing 1 further includes a comprehensive protection module 2 and a carrier communication module 3. The carrier communication module 3 is used for communicating with the upper computer. The comprehensive protection module 2 collects current and / or voltage signals in the three phase pole units and acts when a fault is detected, triggering the phase pole unit with a fault or triggering the three phase pole units to disconnect; the comprehensive protection module 2 includes a measurement mechanism and a mode switching mechanism. The measurement mechanism includes a microprocessor (protection chip), a measurement chip, a communication chip, etc. The microprocessor and the measurement chip are connected to the sampling mechanism. The microprocessor is connected to the measurement chip and is also connected to the releases of the three phase pole units; the measurement chip collects current and / or voltage signals in the three phase pole units through the sampling mechanism for high-precision current measurement in the three phase pole units. The microprocessor determines whether there is a fault based on the current and / or voltage signals detected by the measurement chip and acts to trigger the phase pole unit with a fault to disconnect or trigger all phase pole units to disconnect through the release when a fault is detected; the communication chip is used to implement RS485 communication and / or Bluetooth communication and / or CAN communication, etc.

[0095] The mode switching mechanism is provided with a switching switch 20, and the switching switch 20 is connected to the microprocessor of the measurement mechanism to feedback signals, which is used to switch the comprehensive protection module 2 between single-phase operation and all-phase linkage. When the comprehensive protection module 2 is in the all-phase linkage state, if any phase pole unit fails, the comprehensive protection module 2 also simultaneously drives the tripping devices corresponding to all phase pole units to act, causing the operating mechanisms of all phase pole units to trip, unlocking the energy storage mechanisms of the operating mechanisms of all phase pole units, and disconnecting the moving contacts and static contacts of all phase pole units simultaneously. When the comprehensive protection module 2 is in the single-phase operation state, it only drives the tripping device of the faulty phase pole unit to act, causing the operating mechanism of this phase pole unit to trip, unlocking the energy storage mechanism of the operating mechanism of the faulty phase pole unit, and disconnecting the moving contact and static contact of the phase pole unit with fault current. The fault can be any one or a combination of overload, short circuit, short circuit short delay, zero break, over-voltage and under-voltage, and phase break. It can be understood that the number of phase pole units is not limited to three, and can also be two or four phase pole units. As other embodiments, the mode switching mechanism can also not be provided, that is, when any phase pole unit fails, all phase pole units are triggered to disconnect.

[0096] An improvement point of this embodiment is that a connection structure is provided in the housing 1. The comprehensive protection module and the carrier communication module 3 are modularized respectively and are plugged into the connection structure respectively. The comprehensive protection module and the carrier communication module 3 are connected through the connection structure, which can not only be individually unplugged and replaced for the convenience of users, but also the body of the intelligent measurement switch does not contain electronic components, and all electronic components are placed in each module unit, which can effectively realize the life cycle of primary equipment and secondary equipment.

A protruding fixing portion 143 is provided on the side edge of the cover plate 142 close to the operation portion 13. A fixing hole 144 for accommodating the fixing portion 143 is provided on the operation portion 13. The fixing hole 144 is located between the two handles 10. After the cover plate 142 is closed, the fixing portion 143 is connected to the housing 1 through a first screw 145. A first anti-disassembly cover 146 for sleeving on the first screw 145 is provided in the fixing hole 144. The anti-disassembly cover can prevent the first screw 145 from being privately removed. Of course, the cover plate 142 can also be made of an opaque material. The cover plate 142 can also be connected by means of a buckle instead of a screw, and the anti-disassembly cover can also be not provided, which all belong to the protection scope of the present invention.
