The specific design idea is as follows:
the invention relates to fixed high-voltage electrical equipment for power generation, power supply and power distribution, which is mainly used for electrical equipment maintenance, electrical test, power distribution maintenance and security fences required for regional isolation of banks, stations, hospitals and the like, in particular to a GIS high-voltage combined electrical appliance.
Along with the high-speed development of the power technology, the power equipment is updated, the overhaul work requirement and the operation mode are regulated to be changed, the complexity of the structural type and the space arrangement of the power transformation equipment is greatly improved, the problems of heavy traditional safety fence equipment, inconvenient transportation, troublesome assembly and disassembly and the like are gradually highlighted, the workload of operation and maintenance personnel of a transformer substation is increased intangibly, and the problems of difficult fixation, poor wind resistance, easy dumping and the like of the traditional safety fence are also non-negligible potential hidden hazards in the aspect of safety measure arrangement.
The existing primary equipment safety measures of the transformer substation are mainly divided into two types, wherein one type is the work place safety measure which is made by operators for working teams. The other is a hard isolation safety measure which is arranged by a construction unit for strictly distinguishing a construction area from an equipment operation area;
the operators can prevent the operators from working on the primary equipment of the transformer substation to enter, go up and touch the live operation equipment by mistake, or prevent personal injury from taking measures.
Traditional primary safety measures are divided into disc base type, insertion base type and fixed fence net type according to the supporting mode of the safety fence, and each mode has the advantages and disadvantages and is characterized as follows:
1. common problem:
the fixing is not firm, and the fixing is easy to topple under the influence of external force in the use process. The operation and maintenance personnel are arranged by experience, so that the operation and maintenance personnel are difficult to horizontally and vertically arrange and are not attractive.
2. Single problem:
the fixed bracket type telescopic fence is mainly used for safety measure arrangement of indoor equipment such as a relay protection room screen cabinet, a switch cabinet and the like, can be spliced, but has inflexible corner, longer bracket legs and inconvenient transportation.
The inserted soil type metal support leg is in a combined mode of the inserted rod and the purse net, the spliced corner is flexible, the inserted soil type metal support leg is only suitable for soft ground, cannot be used on hard ground, and the weight of the inserted rod metal support leg is large.
The disc base is mainly used on hard ground, the base is large and heavy, the assembly and disassembly process is complex, and the workload of operation and maintenance staff is increased.
The inserted link embedded pile type is that the pile is embedded underground, the construction is complex, the maintenance is difficult, and the one-time investment for installing the pile at a distribution point is large.
3. Improvement direction of safety fence:
through the comparison of several safety fences (purse nets) mainly used by the current transformer substation, in combination with the actual safety measure requirements of the transformer substation, the improvement direction of the safety fences mainly surrounds the following points:
(1) the fence needs to be firmly fixed at the root, has wind resistance and is not easy to fall down.
(2) The inserted link is to select light material, simplifies support foot structure simultaneously, reduces the transportation burden.
(3) The fence structure is optimized, the installation and dismantling processes are simplified, and the load of operation and maintenance staff is reduced.
(4) The method has applicability to hard and soft ground, simplifies the pre-buried foundation structure and reduces the cost.
(5) The pre-buried point location is combined with the actual equipment arrangement of the transformer substation places, especially considering the conditions of more combined electric appliance struts and frameworks
In condition, the embedded point positions need to be flexibly set so as to adapt to the arrangement requirements of various maintenance work safety measures.
(6) Considering the locking function of the security fence, preventing artificial damage to the security measure
(7) On the basis of realizing complete fence functions, the purse seine is flat, horizontal, vertical, tidy and beautiful as much as possible.
4. The specific technical structure is as follows:
the multifunctional upright post combined safety fence developed by the inventor is a means for effectively guaranteeing personal safety of GIS equipment overhaulers and equipment safety isolation and warning, improves safety and reliability of equipment in maintenance, reduces field management cost, fills the gap that standardized safety measures for field overhaul of GIS equipment lack of systematicness for a long time, provides standardized guiding measures for field safety production, and is a new technical product required to be used in various fixed electrical equipment overhaul and maintenance operation safety measures.
The utility model provides a multifunctional upright post combined safety fence is an innovation to safety fence, purse seine or warning area that uses in the electric power system, mainly solves following problem:
(1) the heavy physical labor of operation and maintenance personnel is effectively reduced.
(2) Effectively solves the problems that the safety fence, the purse net or the warning belt is easy to fall down and is not placed normally when being influenced by external force in use
Problems.
(3) The safety fence, the purse net or the warning belt can be effectively controlled, and the safety fence, the purse net or the warning belt has the problems of various varieties, inconvenient use, high damage rate after use and difficult storage and management after use.
The multifunctional upright post combined safety fence is used as a parent body, and when operation and maintenance personnel arrange safety measures, used varieties can be adjusted according to the actual field requirements, such as: fence, purse net, warning belt, etc.
The multifunctional upright post combined safety fence mainly comprises a ground buckle locking disc, a purse net or a warning belt and a combined upright post part.
1. The ground knot locking disk comprises the following components: the floor lock disc is provided with a boss corresponding to the floor lock disc.
2. The combined upright post comprises the following components: insulating rod, barrier round pin, stop circle, multi-functional string cover, stand chuck, stand top is equipped with the capping lid, and stand chuck fastening is in the bottom of combination stand, stand chuck component: the chuck housing, the locating pin or the screw, the limit sleeve and the buckle play a role in protecting the buckle, and the boss outside the housing can assist in locating during operation.
The specific operation steps are as follows:
when the operation and maintenance staff hangs the safety isolation fence according to the requirement, the stand column is only required to be transported to the site, and the chuck on the stand column is inserted and fixed on the ground buckle plate according to the requirement, and the concrete implementation mode is as follows:
1. and (3) column locking: and aligning and pressing the card cover socket mark at the bottom of the upright post with the locking function with the starting point mark of the card seat, and rotating clockwise by about 45 degrees, wherein the upright post and the card seat are automatically locked at the moment.
2. Hanging a net: the purse seine is hung at the upper hook of the upright post, and if the purse seine is locked, the purse seine can be locked by pushing the locking plate into the locking plate groove on the upright post and enabling the locking plate to be meshed with the bottom end of the locking plate.
3. And (3) net collection: the key is inserted into the control lock, the control lock is opened by clockwise rotation, the net hanging lock plate automatically pops out of the lock plate groove at the moment, the net can be collected, and then the key can be taken out by anticlockwise rotation of the key.
