Abstract
The utility model, which belongs to the security protection technical field of the central-positioned handcart power switch cabinet, brings forward an electromagnetic blocking device of a contact baffle plate of a central-positioned trolley power switch cabinet. The blocking device is composed of a baffle plate valve (7), a baffle plate connecting rod (3), a handcart, a handcart guide rail (8), a control circuit board (1), and stop electromagnets (5); and the control circuit board (1) controls the electrification and interruption of the power supply of the stop electromagnets (5). With utilization of the device, the operator can be prevented from touching the electrified part by mistake, thereby reducing the security risk during the maintenance process of the central-positioned cabinet. Therefore, the occurrence of the casualty accident in the maintenance work can be eliminated completely and thus intangible economic and social benefits can be produced.
Description
Technical field
The utility model relates to the safety device of 10kV middle wheelbarrow switch cabinet, specifically relates to the locking device of handcart switch cabinet contact baffle plate.
Background technology
The locking device of handcart switch cabinet contact baffle plate is a kind of when handcart parts in the switch cubicle overhaul, and reliable locking contact baffle plate prevents the safety device at personnel's mistakenly entering into charged position.Along with continuous expansion and the reinforcement of China's power grid construction, advantage has obtained popularization and application widely to middle wheelbarrow switch cabinet because its structural volume is little, closing speed is fast, drop-out current is big etc.According to the GB3906 standard code, the handcart circuit breaker of intermediate switchgear cabinet should make valve be locked in off-position independently when safeguarding or testing.Intermediate switchgear cabinet has following several reasons can cause baffle plate to open by mistake and opens in the application of reality: baffle plate is opened the connecting rod bite, causes the interior charged position of contact of cabinet exposed; The operator safety prevention awareness is not in place, arbitrarily broadens the scope of work; The various uncertain factors of baffle plate linkage etc. are bumped in site operation personnel's false touch.All there is weak point in existing switch cubicle baffle plate locking device, perhaps complex structure, and perhaps locking is unreliable, has certain potential safety hazard, threatens operating personnel's personal safety.
The utility model content
In order to overcome above-mentioned defective of the prior art, the utility model provides a kind of intermediate switchgear cabinet contact baffle plate blocking mechanism, and is simple in structure, and safe and reliable.
A kind of middle dolly power switch cabinet contact baffle plate electromagnetic locking device comprises baffle plate valve, baffle plate connecting rod, handcart, handcart guide rail and control circuit board; Baffle plate valve, baffle plate connecting rod and control circuit board are installed on the sidewall of switch cubicle, and the handcart guide rail is fixed on the bottom surface of switch cubicle; Handcart is mobile in the handcart guide rail, and the baffle plate connecting rod is equipped with baffle plate connecting rod movement arm in both sides up and down; The baffle plate valve drives opening and closing by the baffle plate connecting rod, and it is characterized in that: this locking device also comprises the stop electromagnet, and the stop electromagnet is installed in the side of baffle plate connecting rod, and relative with baffle plate connecting rod movement arm; The stop electromagnet is connected with lead with control circuit board, the power on/off of control circuit board control stop electromagnet.
This middle dolly power switch cabinet contact baffle plate locking device has been eliminated effectively because artificial mounts the potential safety hazard that procedure lock produces at the contact baffle plate, has guaranteed the fail safe of operation and service work; Further improved the automation and intelligentification degree of contact baffle plate blocking mechanism, avoided saying that because of a pipeline equipment job bus equipment all has a power failure, enlarged the overhaul of the equipments scope and cause electric quantity loss.
Description of drawings
Fig. 1 is the structure chart of this device embodiment;
Fig. 2 is the control circuit board schematic diagram of this device embodiment;
Fig. 3 is the schematic diagram of this device and switch cubicle integral body.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, bus-bar room, static contact head device, trigger device, baffle plate valve 7, baffle plate connecting rod 3, stop electromagnet 5, handcart guide rail 8 and control circuit board are installed in the switch cubicle 6.Fixed contact is installed in the bus-bar room, it faces the moving contact that is separated by baffle plate valve 7, moving contact is installed on the wheelbarrow switch of handcart, handcart moves freely in handcart guide rail 8, baffle plate valve 7 drives its opening and closing by baffle plate connecting rod 3, stop electromagnet 5 is installed in baffle plate connecting rod 3 sides, with baffle plate connecting rod movement arm 4 over against, and secure fixation is on switch cubicle 6 madial walls.Stop electromagnet 5 connects to form total system with control circuit board 1 usefulness lead 2.
Contain the microcomputer control circuit in the control circuit board 1, it comprises power control circuit, power electronic circuit, range finding electronic circuit, AccessPort circuit and display circuit.
When wheelbarrow switch need test and overhaul, when handcart is shifted onto from the service position the process of experiment position, control circuit board 1 judges that by the range finding electronic circuit position that handcart pulls out is to control stop electromagnet 5 work of whether switching in cabinet, after 5 energisings of stop electromagnet, stop electromagnet 5 tightly adsorbs baffle plate connecting rod movement arm 4, make that baffle plate connecting rod movement arm 4 can't be movable, thereby make 7 the being forced to property lockings of baffle plate valve, bump charged position to avoid mistake.When handcart when the experiment position is advanced to the process of service position, control circuit board 1 is judged the position that handcart advances by the range finding electronic circuit in cabinet, whether control stop electromagnet 5 cuts off the power supply, 5 outages of stop electromagnet quit work, stop electromagnet 5 discharges baffle plate connecting rod movement arm 4, baffle plate connecting rod 3 can freely be opened baffle plate valve 7, does not influence pushing of handcart.
Claims (2)
