A kind of current transformer erecting device
Technical field
This utility model relates to the auxiliary installing device of a kind of electric load monitoring terminal, particularly relates to a kind of Current Mutual Inductance
Device erecting device.
Background technology
At present, in the area of a large amount of power consumption such as city, cities and towns, rural area, in order to ensure power system security economy
Operation, it is necessary to the ruuning situation of power equipment is carried out monitoring and measuring, and this cover system is referred to as electric load monitoring terminal,
But owing to the magnitude of current span of power system is very large, general measurement and protection device cannot directly access a sub-high pressure and set
Standby, and need to become the big electric current scaling transformation of primary system small area analysis, supply measuring instruments and protection device use.
In the circuit of power consumption, electric current differs greatly, and has to several Wan An from several peaces, is measuring the big of alternating current
During electric current, need to be converted to the electric current that comparison is unified for ease of secondary meter measurement, have employed this device of current transformer, electricity
Current transformer is widely used in primary side and is connected on the fields such as primary system, secondary side joint measuring instruments, relay protection.
Current transformer is that in power system, the secondary device such as measuring instruments, relay protection obtains electrical primary loop current
The sensor of information, current transformer primarily serves big electric current scaling transformation and becomes standard small area analysis, it is achieved thereby that measuring instrument
Table, protection equipment and the standardization of automatic controlling device, miniaturization.Current transformer may further be used to separate high voltage system simultaneously
System, to ensure the safety of the person and equipment, therefore current transformer plays abnormal important effect in power supply or distribution system.
And in transformer station's high-voltage board, often need to install or change current transformer, and generally need manually to install, existing
Two workmans are at least needed to cooperate installation in power supply or power distribution equipment during the bigger current transformer of installation volume: a work
Current transformer is held up and makes it with installing hole to it by people, and another workman utilizes bolt to be fixed by current transformer.This
The working method production efficiency of sample is relatively low, simultaneously because current transformer is heavier, also can cause industrial injury when workman exerts oneself careless, danger
The personal safety of evil workman, is therefore badly in need of the lifting erecting device of a kind of current transformer.
Utility model content

Technical solution of the present utility model is:
A kind of current transformer erecting device, including guide rail, railcar and hoisting apparatus, described railcar includes four
Wheel and two sliding axles;Described wheel and the supporting setting of guide rail;Four pieces of slide blocks it are provided with on described sliding axle;Described lifting
Device is arranged on the sliding axle of railcar by slide block;Described hoisting apparatus includes jack plate, lower jack plate and scissor type
Gripper shoe, is separately installed with scissor type gripper shoe between described upper jack plate and lower jack plate, the left end of scissor type gripper shoe divides
Not with upper jack plate and lower jack plate fixed-link, the right-hand member of scissor type gripper shoe is fixedly connected with gripper shoe scroll wheel;Described
Pallet it is provided with on hoisting apparatus.
It is further preferred that be provided with the steel pipe of band internal thread in described lower jack plate, the steel pipe of described band internal thread is cut with fork
Formula gripper shoe links, and is provided with full thread leading screw in the steel pipe of described band internal thread, and the end of described full thread leading screw is fixing to be connected
There is crank.
It is further preferred that described hoisting apparatus is respectively arranged with two groups, hold up pallet the most side by side.
It is further preferred that be provided with magnetic attracting device in described pallet, described magnetic attracting device is provided with Magnetic sucking switch.Magnetic
Device is possible to prevent current transformer to slide on the weight-bearing surface of pallet.
It is further preferred that described crank is " Z " font crank.
It is further preferred that the left end of described scissor type gripper shoe passes through steady pin with upper jack plate and lower jack plate respectively
Connect.
In above-mentioned erecting device, railcar can move forward and backward on guide rail, and hoisting apparatus passes through slide block at track
Can horizontally slip on car, pallet is for placing heavy current transformer, and personnel can utilize crank shake to adjust electricity up and down
Current transformer height, so just can be with easy adjustment transformer position during installation current transformer.
This utility model has the advantages that compared with the prior art
Current transformer of the present utility model moves erecting device, when current transformer moves installation, and can be easily
Adjust current transformer up and down, around move, so need to install or change current transformer in transformer station's high-voltage board
Will be the most convenient, save manpower.
