Description

A kind of plug-in strip mast-up
Technical field
The utility model relates to converting station electric power maintaining equipments device, and more specifically, the utility model relates to a kind of plug-in strip mast-up.Described plug-in strip mast-up is a 220KV7 type plug-in strip mast-up, and described 220KV7 type plug-in strip mast-up structure is small and exquisite, easy to use, and safety is big.
Background technology
In the electric system, electrical equipment installation and maintenance device circuits such as the electrical generator of substation, voltage transformer etc. must guarantee to isolate alive part, promptly guarantee staff's safety etc.
In order to finish aforesaid operations, must the installing device for switching in electric system.Owing to change operation scheme or et out of order, in the time of they need being inserted or withdraw from, require reliably and neatly to carry out blocked operation.For example: under circuit et out of order situation, rapid disengagement failure electric current is limited in accident some areas and makes not that et out of order partly continues operation, to improve the reliability of power supply.
When repair apparatus,, it can be divided into following a few class according to the different performance of device for switching:
Device for switching such as low pressure disconnecting link switch, contactless switch, high voltage load switch are used for cut-offfing under normal operation or closed running current.
Fuse is used for cut-offfing overload electric current or short circuit current.
High voltage isolator only is used for isolating power supply when maintenance, does not allow to cut-off or closing current with it.
Automatically breaker is used in predetermined memory time according to selected counts at automatic disjunction faulty line of currentless moment.
Device for switching such as primary cutoff, low-voltage air switch both had been used for cut-offfing or closed running current, also was used for cut-offfing or closed overload electric current or short circuit current.
Owing to change operation scheme or et out of order, in the time of they need being inserted or withdraw from, reliably and neatly carry out blocked operation in order to guarantee.For example, for promoting the safety assurance of urban distribution network control system, must implement to change to certain substation's disconnecting link and transform.At this moment, bonding bussed supply simultaneously, this is safe and the difficult problem of technical maximum.It need build maintenance framework platform and manual chain block lifts, and does not have the highway of going in ring in this substation, and haulage equipment and aloft work are restricted; Especially device structure is old-fashioned, and disconnector and adjacent charging equipment distance have only 3.5 meters, and the space of staff's activity has reached the limit.Before each replacing disconnecting link, the necessary operation of falling the bus for this reason, need be finished more than 200 operational motion and program.It is numerous and diverse to work, and work capacity is big.
In the past, when building maintenance framework platform and manual chain block and lifting, because power-off condition is different, to the plug-in strip lifting, particularly the hanging method of 220KV7 type plug-in strip lifting also had very big difference.For example, can not use crane lifting sometimes and change artificial mast into, so at first need perpendicular mast of more personnel and pulling cable wind rope, secondly the height of mast self whether to around electric equipment influence arranged, increase work capacity once more greatly and be unfavorable for keeping the safety in production.In addition,, adopt artificial mast lifting, can be subjected to restrictions such as condition, environment because crane can not use, in specific time, can not completing task on time.
The utility model content
For overcoming the problems referred to above, the purpose of this utility model is, a kind of plug-in strip mast-up is provided, and described plug-in strip mast-up structure is small and exquisite, easy to use, and safety is big, is not subjected to restrictions such as condition, environment, improves the safe operation situation of electrical network.
The following realization of plug-in strip mast-up of the present utility model:
A kind of plug-in strip mast-up comprises lifting by crane and uses monkey spar that it is characterized in that described mast-up is formed by round steel pipe manufacturing, monkey spar length is 3.1-3.2 rice.
According to plug-in strip mast-up of the present utility model, it is characterized in that described plug-in strip mast-up detachably is made of upper and lower two joints, joint is of a size of 1.5-1.6 rice on it, and it saves down and is of a size of 1.8-1.9 rice, middle bolt together.
According to plug-in strip mast-up of the present utility model, it is characterized in that described suspension bracket is fixed on the plug-in strip footing, and described plug-in strip foundation bolt is being fixed on the plug-in strip base plate of fixed bottom boundary.
According to plug-in strip mast-up of the present utility model, it is characterized in that the round steel pipe of described mast-up is the round steel pipe of 80 * 5mm.
According to plug-in strip mast-up of the present utility model, it is characterized in that described plug-in strip footing is No. eight channel-section steels, processing length is 500-650mm, offers 4 holes on the described channel-section steel, distance is 10-15mm between the described hole.
According to plug-in strip mast-up of the present utility model, it is characterized in that described plug-in strip base plate is done as above-mentioned plug-in strip footing, processing length 500-650mm offers 4 holes, and distance is 10-15mm between the described hole.
Thus, can be used for regulating the width of plug-in strip footing, same material is also used in the below certainly, and same length and eye distance are connected and fixed with overbolt.
According to plug-in strip mast-up of the present utility model, described plug-in strip mast-up structure is small and exquisite, and joint is detachable up and down, and easy to use, safety is big, is not subjected to restrictions such as condition, environment, improves the safe operation situation of electrical network.
