Background technology
The electrical equipment line parameter circuit value of power plant, substation is the foundation calculating the item evaluation work such as electric network swim, short circuit current, voltage, stable, relay protection setting, and its correctness is significant for guarantee power network safety operation.In order to have one truly, accurately to hold to the parameters of circuit, specifically must measure the line parameter circuit value of circuit.This is for the safety of accurate evaluation substation, guarantees that the equipment reliability service tool of electric system is of great significance.Conducting transmission line parameter testing and other protection wiring are special and other protection wiring processes; different according to the requirement of surveyed parameter; in positive sequence impedance and zero sequence impedance test process; need to carry out three phase short circuit and three phase short circuit ground connection with three-phase ground line respectively to institute's survey line road, to meet corresponding test condition.During as carried out positive sequence impedance test, adopting corresponding voltage class insulating bar according to voltage of system grade, grounding jumper being fixed on hanging wire insulating bar carrying out grounding jumper simultaneously.In traditional positive sequence impedance test, by testing crew, insulating bar is lifted the hanging wire carrying out grounding jumper, owing to being three phase line, hanging earthing conductor needs to carry out three times, due to the limitation in height of insulating bar and manpower restriction in hanging earthing conductor process, often make grounding jumper not contact firmly fully with circuit, this just makes a large amount of muscle power of testing crew consumption carry out repeatedly hanging earthing conductor to reach test condition.In traditional circuit parameter experiment hanging earthing conductor process, there are the following problems: one is that (220kV insulating bar is made up of four joints with manually lifting insulating bar, totally 8 meters long, after band electrical test examination line, weight can reach 10 kilograms) consume one's strength, the firmness of hanging earthing conductor, the firmness of usual hanging earthing conductor, can not meet test request; Two is that the electrical equipment that circuit can be caused to connect in testing crew extension electrical test line (insulating bar rocks after 6 meters) process rocks, and easily causes device damage; Three is that the area of contact of grounding jumper and circuit is bad, causes test figures unstable; Four is need personnel many, and usually need 2-3 people to complete, work efficiency is lower.
Summary of the invention
The utility model is exactly to solve the problems of the technologies described above, and provides a kind of portable electric test connection insulated lifting device, and this device is easy to carry, simple to operate, adjustable length, and can need fast grounding jumper to be installed according to testing crew, and work efficiency is high, cheap.
The technical scheme of the utility model technical solution problem is to achieve these goals:
A kind of portable electric test connection insulated lifting device, comprise castor, gear, it is to be fixed on two axles on casing and is respectively equipped with pitch wheel I, II; The shaft end of any one in this gear I, II is provided with rocking bar; The adapting position of the circumference of described gear I, II is connected respectively the pole of shelf support lower end; The pole of this shelf support upper end is connected with geometrical clamp, and described bottom half is provided with four castors.
Described shelf support is intersected between two by some poles, and is connected by bolt and forms.
Described shelf support is made up of insulating material.
Described geometrical clamp adopts " recessed " character form structure.
Described castor is insulation universal caster wheel, and with fixing clamp on castor.
Owing to adopting technique scheme, the utility model is made compared with prior art to have following beneficial effect:
The utility model be to overcome artificial lift dangerous in insulating bar process, efficiency is low, consume one's strength the drawback such as large.Have easy to carry, support is detachable, mechanical strength good, lifting is steady, load carrying ability is large, fast power-saving, safe and reliable and work efficiency high.Thus meet the needs of power transmission and transformation line power frequency parameter test and other protection wiring, be easy to promote the use of.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is the left TV structure schematic diagram of the utility model Fig. 1.
Vital parts in figure: geometrical clamp 1, shelf support 2, bolt 3, rocking bar 4, casing 5, gear I 6, castor 7, gear II 8.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is further elaborated, but protection domain of the present utility model not limited by specific embodiment, is as the criterion with claims.In addition, with without prejudice under the prerequisite of technical solutions of the utility model, any change that the those of ordinary skill in the art done the utility model easily realize or change all will fall within right of the present utility model.
Embodiment 1
A kind of portable electric test connection insulated lifting device as shown in Figure 1 and Figure 2, comprise castor, gear, two axles are provided with in its casing 5, and be fixed on casing 5 wall, these two axles are respectively equipped with pitch wheel I 6, gear II 8, the axle that the shaft end of gear I 8 leans out casing 5 part is fixed with rocking bar 4; On the adapting position of the periphery of gear I 6, gear II 8, the pole of shelf support 2 lower end of making respectively by bolt and insulating material is connected; The pole of shelf support 2 upper end is connected with " recessed " font geometrical clamp 1 by bolt, is provided with four insulation universal caster wheels 7 with fixing clamp bottom casing 5.
Embodiment 2
A kind of portable electric test connection insulated lifting device, comprise castor, gear, two axles are provided with in its casing 5, and be fixed on casing 5 wall, these two axles are respectively equipped with pitch wheel I 6, gear II 8, the axle that the shaft end of gear I 6 leans out casing 5 part is fixed with rocking bar 4; On the adapting position of the periphery of gear I 6, gear II 8, the pole of shelf support 2 lower end of making respectively by bolt and insulating material is connected; The pole of shelf support 2 upper end is connected with geometrical clamp 1 by bolt 3, is provided with four insulation universal caster wheels 7 with fixing clamp bottom casing 5.
When the utility model specifically uses: geometrical clamp 1 is by manual operation rocking bar 4 driven gear I 6, gear II 8 and being elevated.According to lifting principle, gear I 6, gear II 8 drive shelf support 2.Shelf support 2 can be raised to desired height as rotated clockwise rocking bar 4, test connection is fixed on the line after arriving desired height by geometrical clamp 1.Otherwise grounding jumper rotates counterclockwise rocking bar 4 after installing, shelf support 2 can be fallen dismounting geometrical clamp 1.
