Embodiment Construction
[0017] Such as Figure 1-Figure 5 The knife switch anti-misoperation mechanism of a fully mechanical five-proof 10kV switchgear shown includes a knife switch installed on the cabinet body 1 of the switch cabinet, an intelligent lock for driving the interlock mechanism of the switch cabinet, and a knife switch It includes a rotating shaft 2, a locking disc 3 and a handle 4. One end of the handle 4 is fixed on the rotating shaft 2. The middle part of the locking disc 3 passes through the rotating shaft 3 and is fixed on the rotating shaft 3. The handle 4 drives the locking disc 3 to rotate through the rotating shaft 2. The opening and closing of the knife switch is realized after the angle α, the angle α is generally in the range of 90°~180°, and the smart lock includes a key and a lock cylinder. After the key 5 is inserted into the lock cylinder 6, when the key 5 and the lock cylinder 6 correspond to the program, the interlock mechanism of the switch cabinet will be unlocked, a...

The invention discloses a disconnecting link anti-misoperation mechanism of a full-mechanical five-prevention 10kV switching cabinet, which comprises a disconnecting link and an intelligence lock, wherein the disconnecting link comprises a rotating shaft, an interlocking plate and a handle, the intelligence lock comprises a key and a lock cylinder, a first locking groove and a second locking groove are arranged on the interlocking plate, a linking pin extends from one plate surface of the interlocking plate, and a connecting lever is fixed on the lock cylinder. The disconnecting link anti-misoperation mechanism also comprises a linking plate, an interlocking rod, a swinging hook, a first spring and a second spring, wherein the interlocking rod is arranged above the interlocking plate along the radial direction of the interlocking plate, a stretching part and a third locking groove are arranged on the interlocking rod, and the stretching part is connected with the connecting lever; the linking plate is sleeved on the rotating shaft, a lubricating part is arranged between the linking plate and the rotating shaft, a curved groove is arranged on the linking plate, the linking pin penetrates through the curved groove and is connected with the curved groove in a sliding manner, and a back lock heave is arranged on the linking plate; a hook head of the swinging hook faces towards the interlocking rod, and the back surface of the hook head is fixed on the cabinet body of a switching cabinet horizontally through the second spring. The disconnecting link anti-misoperation mechanism of the full-mechanical five-prevention 10kV switching cabinet is capable of preventing disconnecting link anti-misoperation of the switching cabinet.
Description
technical field [0001] The invention relates to a 10kV switchgear in an electric power system, in particular to a fully mechanical five-proof 10kV switchgear anti-misoperation mechanism for a knife switch. Background technique [0002] The 10kV switchgear (referred to as the switchgear) in the power system includes a switch (Isolator, isolation switch) and a switch (Circuit Breaker, circuit breaker) connected between the 10kV busbar and the output terminal. Generally, the knife switch is used as an isolating switch. It includes a locking plate and a handle. Turning the handle can drive the locking plate to rotate to realize the opening and closing of the knife switch. Due to the danger of high voltage, the operation safety of the knife switch must be ensured, and the knife switch is required to have five Anti-proof function, each switch and switch in the switch cabinet group must be operated in sequence, and it is not allowed to operate the switches of other switch cabinets ...
