ZE4195 Electrical Trainer Primary Electrician Training Device Vocational Training Equipment Educational Equipment 1 Product overview 1.1 Profile This training device includes a variety of types of basic electrical control device and measurement, through the relevant experiment, can be familiar with lighting circuit, motor control circuit, measuring circuit connection methods, such as to master its control principle and control mode, the corresponding knowledge and skills, suits, higher vocational colleges, secondary vocational schools and vocational school related professional teaching and skills training examination. 1.2 Feature 1. The electrical control line components are installed on the mounting board of the wall board, which is convenient to operate and easy to replace, so as to facilitate the expansion of functions or develop new training; The choice of operation content is typical, practical and scientific. 2. The operating table can be put into use only with the ac power supply of three-phase four-wire; 3. The skills training with the control circuit and the special design of small motor, can simulate the factory in all kinds of electric drive system, can meet the installation, debugging, maintenance electrician, failure analysis and troubleshooting skills training requirements; 4. All the components of the relay contact control line are connected to the terminals via wires. The wiring of the students' wiring is only needed to protect the components; In practice, the line is used to train the process. 5. The output power have the monitor display and short circuit protection function, when training occurs when wrong operation or caused by wrong wiring short circuit, the device can automatic protection, avoid burning fuse and damage electrical appliances, security training smoothly; 6. The training platform has a good safety protection system. The connection between the practical training circuit and the device power supply is connected through the safety socket and high reliable protective sleeve structure pistol, which is safe and fast. 2 Capacity parameters （1） Input power: three phases, five wires 380V±10% 60Hz （2） Dimension: 1600mm×800mm×1500mm （3） Whole capacity: ＜1.5KVA （4） Weight: ＜150kg （5） Work condition: environment temperature -10℃～+40℃ relative humidity ＜85%（25℃） 3 Product consist of 3.1 Power control panel The control screen is an iron double-layer subsurface airtight spray structure, aluminum plastic plate. The main control panel is equipped with resources: 1.Three phase four wires power input, go through electrical rotector, main switch, go through start button, stop button, control contact connet or disconnect, and set emergency stop button. 2.There is a 450V point type AC voltage meter 1 piece on control panel, through band switch can observe three electrical power grid voltage. 3.AC low voltage power supply: equipped with transformer 1 set, AC voltage primary side 220V, secondary side 24V and 6.3V AC voltage, 6.3V for signal indicator light power supply, 26V for the AC power supply of rectifier circuit in energy consumption braking; 4.4 pieces of 5408 diode, it is usef for dynamic braking rectifying circuit. 5.Three pieces of 75Ω/75W resistor is used for electric motor reduction voltage starting,one piece of 10Ω/25W is used fordynamic braking of asynchronous motor. 3.2 Training workbench The actual training table is an iron double layer subglazed structure, the tabletop is fireproof, waterproof, wear-resistant high density plate, the structure is firm, the modelling is beautiful and generous. There are two drawers (with a lock) on the left and right sides of the table, with cabinets, which can be used to place the hanging pieces and the actual training items, and the structure is strong and beautiful. 3.3Training components hanging box configuration （1）Breaker and contactor module This module contains 2P residual-current circuit breaker (RCCB), fuse socket and three pieces of contractor.
