Substation and 10KV power distribution system pouring training device

 

With the increase in large and medium -sized enterprises in my country year by year, the power industry has developed rapidly, the power grid is becoming more and more complicated and diverse, and the connection between the same voltage level and different voltage levels is also very close. In this case, the correct door to the door is particularly important.

 

"35KV substation and 10kV power distribution system pouring operation screen" is a tr--ning device specially developed for the transformation of the substation. This system cont--ns three voltage levels of 35KV, 10KV and 0.4KV: 35KV has 4 routes, and the double mother belt contacts; the 10kV side uses single -mother segments, two in two outs, ring network power supply; 0.4kV side uses single mother points. Duan, and has a spare power generation system. In this typical 35KV substation model, students can carry out pouring operations under various operating conditions. The voltage level and line of the substation can also be designed according to the user requirements. Therefore, this device is suitable for tr--ning and assessment of all kinds of vocational colleges, power companies, vocational skills tr--ning departments and other institutions.

1. Experimental purpose and principle:

The task of treatment of water is to improve the quality of water, which makes it meet the water quality standards for drinking water and industrial production water.

This device is a medicine before the pump. The pump impeller is quickly mixed to quickly and evenly disperse the downtime water, which immediately dissolves, and the chemical reaction occurs, so that the colloid impurities in the water form a tiny velvet body. This process can be completed within 10-30 seconds (the water temperature is low and it will not exceed 2 minutes). In order to quickly sink the impurities particles, it must also have particles with larger particle size (0.6 ～ 1.0mm) and sufficient weight and strength (not easy to break). The task of the reaction phase is to create hydraulic conditions, so that the micro velvet can be condensed into a "alum flower" visible to the naked eye in a cert--n practice, and then enter the sedimentation pool to precipitate. The sedimentation tank uses a 60 ° sedimentation tank, which m--nly removes the suspended particles that can be removed through the effect of sinking. According to the theory of shallow pond, when the suspended particles are free to settle, the shallower the pool is shallow, the smaller the sinking speed of the suspended particles that can be intercepted, and the larger the intercepted suspended particles. This theory is suitable for pre -sinking pools for dr--nage treatment.

The process of this set of water plants, its theoretical and technical research, allows students to achieve the following goals:

1. Understand the process and technical design parameters of the wastewater factory;

2. Deepen the understanding of the basic concept of the water plant experiment.

2. M--n technical indicators and parameters:

1. Environmental temperature: 5 ℃ ～ 45 ℃

2. Treatment of water: 0.5 ～ 1m3/h,

3. Water inlet turbidity: 30 ～ 100 °,

4. Water turbidity: 2 ～ 5 °,

5. Filtering speed of fast filter pool: 8 ～ 10m/h,

6. Total size of the device: 3200mm × 500mm × 2100mm

7. Power control system: 1 double -sided sub -light -dense -densely pattern plastic control box, leakage protector, voltage meter, lock button switch, wire tube, etc.
