Description

Power grid line load tolerance testing device

Technical Field

The application relates to the technical field of power grid line detection, in particular to a power grid line load tolerance testing device.

Background

The power line is a conductor loop for connecting the power transformation and distribution station with each electric energy user or electric equipment, and the power source end (the power transformation and distribution station) transmits and distributes electric energy to the load end (the electric energy user or electric equipment).

The circuit is designed to handle limited amounts of electricity, and overload can occur when you consume more than the safe carrying capacity of the circuit, which consists of wiring, circuit breakers (or fuses in old wiring systems) and devices (such as lamps, appliances and anything plugged into a socket), the amount of electricity used by each device (in operation) can increase the total load of the circuit, and exceeding the rated load of the circuit wiring can cause the circuit breakers to trip, cutting off the power supply to the entire circuit.

Therefore, after the whole power line is built, regular detection is needed to be carried out on the whole power line, the limit total power under the safety state of the power line is determined, and then the whole power line is prevented from being lowered due to aging of the power line after the power line is used.

However, conventional grid circuit testing typically requires an operator to energize the circuit and then detect the voltage and current of the detector, i.e., complete the test, which is simple and quick but has some drawbacks during actual use:

1. in the prior art, voltage and current are directly detected in a power grid line, and the tolerance of the whole power grid line cannot be detected only in a moment in the detection process, so that the durability and reliability of the whole power grid line cannot be determined in a state that the whole power grid line is electrified and various electric appliances with different powers are arranged.

2. And secondly, when the power grid line is detected, the prior art cannot detect the maximum power of the maximum load under the safety condition in the whole circuit, and cannot detect whether the load calibrated in the actual application process is consistent with the load of the actual circuit.

Thus, under the above stated point of view, there is room for improvement in existing grid line load tolerance testing devices.

When the detection of the maximum power of the circuit under the safety condition is required, an operator presses the start button 82, and at this time, the start button 82 drives the start plate 80 to move downwards through the start rod 81, in the process, the start plate 80 moves downwards, and the start plate 80 presses the special-shaped slide sheet 74 on the rotating belt 72.

Referring again to fig. 10 and 11, the insulating support block 3 is further provided with an automatic detection mechanism 2 for detecting a limit load, and the automatic detection mechanism 2 includes a connecting frame 70, a rotating pulley 71, a rotating belt 72, an automatic detection motor 73, a profile slide 74, and a profile matching block 75.

When the starting plate 80 moves downwards, the starting plate 80 presses down the special-shaped sliding plate 74, and meanwhile, the tightening wheel 103 can effectively ensure the limit of the special-shaped sliding plate 74 under the elastic force of the execution spring 102, so that the special-shaped sliding plate 74 is prevented from deforming when the special-shaped sliding plate 74 extrudes the special-shaped matching block 75.
