Problems solved by technology

However, the existing simulation equipment is only a small simulation system, which is very different from the real system equipment. It is impossible to deeply understand the performance indicators, technical parameters, and the cooperation and interrelationship between the systems and other equipment.
The training method using this small simulation equipment is highly theoretical but lacks practical training, which makes the training effect not good
If you go to the site for training, the personal safety of the trainees cannot be guaranteed, and the on-site equipment may be damaged

Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] Such as figure 1 The simulation training system for the training of residual current protectors and load circuit breakers includes a three-phase four-wire controlled voltage source, and the output of the voltage source is sequentially connected with leakage current and overload protection devices (the comprehensive protection board in the figure ), isolation transformer, ammeter of each phase and isolation switch, the output terminal of the isolation switch is connected to a simulated residual current circuit, which is composed of residual current protectors, dial switches, and leakage current load boxes arranged in series in sequence. The three sets of switch input terminals of the switch are respectively connected to the three-phase output terminals of the residual current protector, and the three sets of switch output terminals of the dial switch ar...

Abstract

The invention relates to a simulated training system comprising a three-phase four-wire program control voltage source. The output of the three-phase four-wire program control voltage source is successively connected with a leakage current and overload protection device, an isolation transformer, ampere meters of various phases and an isolating switch, wherein the output end of the isolating switch is connected with a simulated aftercurrent circuit which is composed of an aftercurrent protector, a dial switch and a leakage current load box, and the aftercurrent protector, the dial switch, theleakage current load box and the aftercurrent protector are successively connected in series; three groups of switch input ends of the dial switch are respectively and correspondingly connected with a three-phase output end of the aftercurrent protector; three groups of switch output ends of the dial switch are respectively and correspondingly connected with a three-phase load of the leakage current load box; the three-phase load is connected in a star shape; and a neutral point is connected to the neutral line of the input end of the aftercurrent protector. The system can satisfy the requirements of the training and the verification of relevant equipment, students can learn to use the relevant equipment in a realer environment and know the operation process and protection well, which is convenient for system verification work and training examination.

Description

technical field [0001] The invention relates to a simulation training system for training electricians, in particular to a training system for simulating the residual current and load of subscriber lines and implementing protection when the tripping protection state is reached. Background technique [0002] In the middle and basic distribution stations (stations) of the power system, there are power inspectors, power distribution operation and maintenance workers (on-duty workers in power transformation and distribution stations), power distribution test and maintenance workers, rural power distribution business workers, relay workers, etc. In order to ensure the safe and stable operation of substations (substations), technical training is required for protection workers, DC equipment maintenance workers, substation commissioning and maintenance personnel, and electrical measuring instrument workers. [0003] Generally speaking, the training must first carry out theoretical ...
