As a result, personal safety is ensured in the operating process and personal injury accident in operation is prevented. Compared with a product in the prior art, the insulation operating rod has substantial advantages of simple manipulation, security and reliability, and ensured personal safety of the operating worker.
Description
Technical field
The utility model relates to a kind of power equipment operation tool technical field, specifically a kind of link rod of measuring load current.
Background technology
The High-Voltage Insulation link rod is the operation tool a kind of commonly used of power industry, that 10 ~ 35KV circuit high voltage link operates indispensable instrument in the power production process, although link rod has passed through some continuous improvement, but still having weak point, is exactly the advanced link rod of a kind of self illumination, electroscope function such as practical novel C N:201570800U.But in the operation of 10 ~ 35KV of reality circuit high voltage link, it is inadequate only carrying out electrical verification, lack quantitative safety instruction, also will be appreciated that the size of operated line load electric current, because it is breakneck behavior that operated line load electric current surpasses regulation, in case the line load electric current surpasses the setting of " rules ", will cause damage to the person, even jeopardize the safety of operator's life.
The utility model content
The purpose of this utility model is a kind of link rod of measuring load current of design, has easy and simple to handlely, safe and reliable, can guarantee operator's personal safety, thus the harm that can avoid load current to overflow human body is caused.
For reaching above-mentioned purpose, the main technical schemes that the utility model is taked is, this link rod that can measure load current is improved at original link rod, have link rod body and order gram hook, it is characterized in that: set up can the measurement circuitry load current device, the measure portion of this device adopts casing current transformer, its magnetic core is by magnetic core top, the magnetic core bottom forms, circuit part is by rectifier, modulus dress parallel operation, liquid crystal display, LCDs forms, current transformer is contained on the link rod, the magnetic core bottom is fixed on the link rod, be provided with the magnetic core rotating shaft on magnetic core top, the backguy fixing hole, magnetic core top can be rotated around the magnetic core rotating shaft, and the spring fixed hole on the spring is installed in the magnetic core rotating shaft.
The utility model provides a kind of desirable charged current measured for power equipment operation tool technical field
Link rod.This link rod of the utility model since be provided with can the measurement circuitry load current device, therefore can find at any time in operation the size of operated line load electric current, size cases that can clear and definite alert line load electric current, guarantee the personal safety of operating process, thus the personal injury accident when stopping to operate.Compared with prior art, have easy and simple to handlely, safe and reliable, can guarantee the remarkable advantages such as operator's personal safety.
Description of drawings
Reach by reference to the accompanying drawings example and further specify specific structural features of the present utility model.
Fig. 1 is assembly structure schematic diagram of the present utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Fig. 3 is schematic block circuit diagram of the present utility model.
Embodiment
Referring to Fig. 1, Fig. 2, this link rod of measuring load current of the utility model comprises: magnetic core rotating shaft 1, backguy fixing hole 2, order gram collude 3, link rod body 4, backguy 5, magnetic core 6, magnetic core bottom 7, current transformer 8, spring, spring fixed hole, rectifier 11, modulus dress parallel operation 12, liquid crystal display 13, DC power supply 14, LCDs 15, backguy operating knob 16, battery 17 and measure portion.Order gram collude 3 and magnetic core 6 be positioned at the upper side end of link rod body 4, liquid crystal display 13, DC power supply 14, LCDs 15, backguy operating knob 16 and battery 17 are located at the downside of link rod body 4.
Below by accompanying drawing the device operation principle is specified:
The measure portion of this device is comprised of current transformer 8, magnetic core top 6, magnetic core bottom 7, carve a groove installs current transformer 8 to enter again in link rod body 4 upper ends, fixing magnetic core bottom 7 with epoxy resin, be designed with magnetic core rotating shaft 1, backguy fixing hole 2 on magnetic core top 6.Magnetic core top 6 can be rotated around magnetic core rotating shaft 1, spring fixed hole on the spring is installed in the magnetic core rotating shaft 1, in the time of needs measurement circuitry electric current, press down backguy operating knob 16 with finger, backguy 5 drop-down backguy fixing holes 2, magnetic core top 6 is rotated counterclockwise around magnetic core rotating shaft 1, the magnetic core collar extension that magnetic core top 6, magnetic core bottom 7 form is opened, line conductor is put into the magnetic core ring, unclamp backguy operating knob 16, under the elastic reaction of spring, magnetic core top 6, magnetic core bottom 7 just close up can the measurement circuitry wire load current.
Carve a groove in the link rod bottom, the large backguy operating knob 16 of recess width that a diameter compares out is installed, connecting stay wire can realize controlling the function of backguy.
Backguy 5 can be selected the nonmetal wires such as high-intensity nylon, chemical fibre.Also can consider on link rod top a rain cover to be installed, prevent that with the gap between protection magnetic core top 6 and the link rod dust, rainwater etc. from falling into wherein, affect the flexibility that rotate on magnetic core top 6.
Circuit part as shown in Figure 3, current transformer 8 is used casing current transformer, its magnetic core is comprised of magnetic core top 6, magnetic core bottom 7, can open flexibly, closure.Rectifier 11 in the circuit diagram, modulus dress parallel operation 12, liquid crystal display 13, LCDs 15 are components and parts commonly used, dc-battery 17 wherein can select common battery to get final product, can be installed in the link rod lower end, be used for providing the quiescent operation power supply of modulus dress parallel operation 12, liquid crystal display 13, because the power consumption of liquid crystal display static state is very little, so do not need to arrange mains switch.
Secondary circuit class of insulation level is improved in the position of the safety when guaranteeing that the user operates, live part people's grasped as far as possible away from operation the time, prevents that CT secondary induced electricity from discharging to human body.
