Technical field
This reality is novel to be related to substation's backman's fixture fields.More particularly to relay protection of power system personnel are doing electric current
Mutual inductor such as spreads at a kind of collapsible CT reference test bar used when work.
Background technique
Currently, electrical equipment reduces equipment spacing and occupied space to save occupied area as far as possible, by equipment it
Between spacing reduce.Especially done in switchgear current transformer spread etc. work require that testing crew crawls into switchgear will
Primary corresponding polar end of the testing wire clamp to CT or PT.When testing crew is crawled into switchgear, very difficult stretch out one's hand is clipped to once
Equipment, and blocking there are also busbar, arrester, instrument etc. in switchgear, so that by equipment one in testing wire clamp to switchgear
Secondary polar end can be extremely difficult.
Summary of the invention
The purpose of this utility model is to design a kind of collapsible CT reference test bar, can free extension, can rotate as needed
Test wire can be connected to equipment in Various Complex situation by holding the clip of control front end by respective angles.
To achieve the above object, the technical solution adopted in the utility model are as follows: a kind of collapsible CT reference test bar, including sequentially
The first pole, the second pole and the third pole of connection；First pole is rotatably connected on the top side of the second pole, the
The tail portion of two poles is rotatably connected on the top of third pole；The axis perpendicular of the rotation axis of first pole and the second pole,
The rotation axis of second pole is vertical with the axis of third pole；It is equipped at the top of second pole for adjusting the first pole rotational angle
Knob；The turned position of second pole also is provided with the knob for adjusting the second pole rotational angle；Peace outside third pole
Equipped with a clip control handle, the first pole includes the interconnecting piece being connected with the second pole and is connected with interconnecting piece
It which is provided with the clip of test wire slot；It is conductively connected between clip and test wire slot；Clip control handle is each by being located at
Flexible axle inside a pole is connected to control the folding of clip with clip, is hollow structure inside each pole so as to conducting wire
It is penetrated from third pole bottom and is embedded in test wire slot after being pierced by the top of the second pole.
The position for getting at and needing to clamp test wire is difficult in manpower, it can be using the utility model as auxiliary.It will
Test wire is walked upwards via the third pole of bottom, after the second pole top sidewall is pierced by, the test that is stuck on clip
In line slot, clip is extended into corresponding position, clip is opened by clip control handle, clip is then clipped into corresponding positions
It sets.Operation and clip by the pitch angle of two knobs adjustable first pole and the second pole, in order to manpower
Clamping.It is removed after the completion of test also easily.
Further, second pole is telescopic pole.
Telescopic pole is convenient to be adjusted in length direction, in conjunction with angular adjustment, can satisfy under more complicated states
Test wire clamping operation.
Further, LED bulb is installed below the clip of the first pole, LED bulb is installed on third pole outer wall
Switch, inside are equipped with battery；LED bulb switch is connected structure by being located at the route inside pole with LED bulb and battery
At current supply circuit.
Collapsible CT reference test bar front end also can accurately clip to when dark with LED searchlight ancillary staff
Correct position.
When collapsible CT reference test bar use can free extension, respective angles can be rotated as needed and can be folded solid
Fixed, test wire penetrates and can be reliably connected the clip of front end inside collapsible CT reference test bar, is shone by small switch control LED
It is bright and clip folding is controlled by hand handle, facilitate the corresponding polar end of connection primary equipment.The utility model facilitates contraction to fold, just
In carrying, do not take up space, low cost, practicability height.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of collapsible CT reference test bar.
The overlooking structure diagram of Fig. 2 the utility model.
The connection schematic diagram of Fig. 3 clip and clip control handle.
The connection schematic diagram of Fig. 4 the second pole and third pole.
The first pole of 1-, the second pole of 2-, 3- third pole, 4- knob, 5- clip control handle, 6-LED bulb switch,
The first rotation axis of 7-, the second rotation axis of 8-, 9- torsional spring, 10- flexible axle；
11- interconnecting piece, 12- test wire slot, 13- clip, 14-LED light bulb.
Specific embodiment
1. can be convenient the connection adjustable angle penetrated between test wire and three pair rod inside collapsible CT reference test bar can consolidate
Fixed, the first pole includes the clip of LED bulb and girdle tests slot.Pole is made of insulating material, knob, flexible axle, handle
It is external also all to be coated using insulating materials.
2. the second pole of collapsible CT reference test bar is responsible for connecting the effect of the first pole and third pole, head and the tail junction
There are adjustment knobs, angle and is capable of fixing between adjustable bar.It is illustrated in figure 2 the position of the first pole and the connection of the second pole
Schematic diagram, the first pole rotates (upper and lower pitch rotation) around first rotating shaft, convenient for angle is adjusted to suitable position；It can in Fig. 4
See that the second pole is connected by the second rotation axis with third pole, can conveniently adjust angle；It can be made by turning knob
Connection at shaft loosens, and then rotates the first or second pole and tightens to suitable position, then by knob.It is needed when operation
The good insulation equipment of wearing.
3. the third pole of collapsible CT reference test bar is provided with battery, LED switch and the hand handle for controlling clip.
As it can be seen that being connected between clip and clip control handle 5 by flexible axle 10 in Fig. 3, clip control handle 5 and third section
Be connected between 3 lateral wall of bar by shaft (lateral wall aperture is equipped with shaft in hole, and handle rotation is located in shaft), shaft
It is equipped with torsional spring, torsional spring (or handle) is connected with flexible axle 10, inwardly mediates handle, and torsional spring (or handle) rotation drives flexible axle 10
It pulls downward on, 10 upper end of flexible axle is divided into two strands, and driving two parts of clip to be turned out respectively (can change flexible axle side by pulley
To), clip is opened；And when handle is failure to actuate (i.e. in holding figure when position), two half parts of clip pass through torsional spring retaining clip
Tightly.This structure can there are many implementations, for example commonly object are taken to press from both sides using sanitationman, the folder of certain the utility model
Son is normally closed.
The utility model Work tool aims at simplified substation and the work such as spreads and design, and has at low cost, easy to use, knot
The features such as structure is simple, practical facilitates the operation of relay protection personnel, improves working efficiency.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, make specifically being altered or varied belonging to the utility model
