Description
Technical field
The utility model relates to the power supply unit in electric power system, specifically a kind of a kind of valve locking device be applicable on high-voltage switch cabinet equipment.
Background technology
We know, anti-misoperation locking device is the visual plant that transformer station prevents " five large types " misoperation, and reliable misoperation-proof locking device is the important leverage of the person, electrical network and device security stable operation." State Grid Corporation of China's 18 great anti-accident measures of electrical network " are pointed out: the product of high-tension switch cabinet should be selected " five prevent " complete function." State Grid Corporation of China's electric power safety working regulation " also clear stipulaties: high voltage electric equipment all should install perfect misoperation-proof locking device.And there is perfect anti-misoperation locking device function, what do not have anti mis-closedown function should install mechanical lock additional.
High-tension switch cabinet is widely used in all kinds of electric substation of electric power system and enterprises and institutions' switchgear house, breaker chamber inside is fixed on contact box inside with the fixed contact that high-pressure side distribution line is directly connected, scurry out to prevent high pressure and hurt sb.'s feelings, be provided with upper and lower valve in the outside of contact box, conventional type switch cubicle only possesses upper and lower valve, does not possess valve locking device, when circuit breaker extracts maintenance out, can the artificial upper and lower valve of manual unlocking, cause fixed contact exposed, bring the potential safety hazard that high pressure gets an electric shock.
Summary of the invention
The purpose of this utility model is exactly to overcome the deficiencies in the prior art, provide a kind of switch cubicle under which kind of state (maintenance or run) all cannot from breaker chamber inner artificial open upper and lower valve, block the contact channels of circuit breaker chamber interior electrification in high voltage part and people thus, completely eliminate the high-tension switch cabinet valve locking device that breaker chamber internal high pressure live part causes potential safety hazard.
The utility model can be reached by following measure:
A kind of high-tension switch cabinet valve locking device, it is characterized in that by bearing, jam plate and spring touch pawl three part composition, jam plate rear end is hinged through bearing pin and bearing, make jam plate can carry out back rotation around bearing pin, touch pawl rearward end to be hinged through pin and pedestal lower end, pedestal upper end is connected with bearing, pin is provided with plane scroll spring, one end of plane scroll spring is connected with support, the other end is connected with pin or tactile pawl, the rear end of jam plate is provided with the isoplanar location-plate with jam plate, touching that pawl rear end is provided with tactile pawl is the connecting plate of vertical configuration, location-plate and connecting plate are hinged, to realize the connection of jam plate and tactile pawl end.
Bearing described in the utility model is frame-type, and the limit, upper end of bearing is provided with connecting plate, and on connecting plate, compartment of terrain is provided with connecting hole, and connecting plate is through rivet and be fixed on the side plate of breaker chamber, to carry out the location of bearing.
Support described in the utility model takes the shape of the letter U, and touch pawl and be arranged in U-shaped support through pin, U-shaped support is connected with bearing through connecting rod.
When the utility model uses, when shaking into circuit breaker cart, handcart two side shield compresses tactile pawl front end in the horizontal direction, touching pawl drives jam plate to rotate to the inside, open interlocking, when shaking out circuit breaker cart, handcart two side shield departs from tactile pawl in the horizontal direction, tactile pawl recovers ortho states under spring force, jam plate is driven to return free state, recover interlocking, when circuit breaker cart leaves breaker chamber, jam plate is still in Interlock Status, upper and lower valve cannot be opened, its advantageous effect one is that locking device possesses perfect " five prevent " requirement, the potential safety hazard of indoor for breaker of switch cabinet high-pressure section can be removed completely, two is that locking device cost is low, high financial profit, three is that each several part in locking device all adopts the manufacture of high-strength stainless steel sheet material, should not damage, compact overall structure, compact, install additional efficient and convenient.
Accompanying drawing explanation
