An overview,
1.1. GG - 1 a (F) (Z) type high voltage switchgear by mistake, the original GG - 1 a type high pressure tank on the basis of improved after adding "five prevention" locked-in send products, it has the following five kinds of prevent wrong operation function; 
Between a. to prevent wrong, wrong points wrong or circuit breaker; 
B. to prevent loading points, isolating switch; 
C. avoid straying into charged interval;
D. prevent charged hang ground;
E. prevent line brake band.
1.2. GG - 1 a (F) the mistake type high voltage switchgear, suitable for 3, 6 and 10 kv ac system for acceptance and distribution of electrical energy (see table 1) have a way.This product is a indoor type, can be in normal operation in the environment of the following:
A. installation height is not more than 1000 meters above sea level;
B. the surrounding medium temperature is not higher than + 40 oc, no less than 20 oc;
C. indoor relative humidity is not more than 85%; 
D. no conductive dust and can destroy the place of gas and metal and insulation; 
E. no explosive dangerous location; 
F. no violent vibration and bo top and vertical gradient is less than 5 degrees.
Second, the technical data and programs
2.1. GG - 1 a (F) (Z) type high voltage switchgear technology parameters are shown in table 2. 
2.2. General atresia primary loop scheme are shown in table 3-1.General closure does not consider 21 ~ 22, 25 to 28, 31 ~ 33 and 37 ~ 39 main circuit scheme, at the same time also does not consider the breaker with CS2 type operating mechanism. 
The primary loop scheme are shown in table 2.3. Simple atresia 3-2.

Q:The role of temperature control switch and pressure switch in automobile air conditioning system The Does the temperature control switch only control the clutch of the electromagnetic clutch of the compressor? Pressure switch in addition to control the electromagnetic clutch switch also control the cooling fan speed? The Seeking expert answers?
Pressure switch is used to adjust the internal pressure of the air conditioning system, air conditioning system, high and low pressure ratio is the key to refrigeration.
Q:What parameters are required for pressure switch selection?
4. Output form (SPDT, DPDT, two SPDT) 5. Whether to require explosion protection 6. What is the total process connection
Q:Car air conditioning compressor pull, but the fan does not turn, with the pressure switch has a relationship? why?
Probably a circuit problem search Asked If the high voltage switch is faulty, will not cause air conditioning fan does not turn? To answer Generally not,
Q:1, the pressure switch and the flow indicator alarm with the control room through the host (automatic) to start the spray pump? If so, the three modules is not set in the host between the logical relationship? 2, the fire occurs, the general is waiting for the pressure switch action automatically start the spray pump, or the central control room to start manually, it is in the central control room between the straight panel is what is the relationship between?
Automatic sprinkler system in the pressure switch, the control room and the relationship between the three spray from the action of the linkage. The pressure switch is always in the normal state. Only in the linkage in the control room and spray pump at the same time in an automatic state, will be linked to the pump. In the fire control center was 24 hours on duty, the linkage in the control room in a manual state. Pump station main pipe installed relief valve, when the pressure exceeds the safety settings, will automatically open valve pressure relief, drainage to the fire pool. So the pipe will not burst over pressure. After the nozzle action, should be directly connected by the pressure switch automatically start the water pump. Pre-action system, rain system and automatic control of the water curtain system, the fire alarm system should be automatically alarmed immediately after the water supply to the distribution pipeline. The control room should be able to show the water flow indicator, pressure switch, signal valve, water pump, fire pool and water tank level, pressure gas pipeline pressure, and power and standby power is in the normal state of the feedback signal, and should be able to control the pump, Valves, electric valves and other operations. In the wet system wet alarm valve on the back of the nozzle action, the system test debugging water or pipeline leakage, etc., through the wet alarm valve part of the flow from the wet alarm valve valve chamber to the delay device; once the delay device filled with water, Hydraulic alarm action, while the pressure switch to send the action signal.
Q:I use the pressure switch to control the pressure of the storage tank, keep at about 8 kg, what type of pressure switch? Please write a specific model, it is best to be the kind of common, and that is, I think the pipeline on a pump a pressure switch seems to have a lot of drawbacks, may I need to increase what? Such as flow switches and the like
Recommended direct use of electrical contact pressure gauge, both can see the pressure can also be achieved control. Pressure switch is not recommended The best control is the frequency converter + pressure transmitter to achieve PID constant pressure control
Q:Air compressor pressure switch wiring?
Air compressor pressure switch about two or three: two-wire control, three-wire control and four-wire control.
Q:Switch mechanical pressure switch and electronic pressure switch what is the difference
Electronic pressure gauge and mechanical pressure gauge, of course, there are differences, such as electronic pressure switch KP46P-02-F1, mechanical KP1-3-01-03-PT, installation in different ways, different performance, the pressure switch is Applicable to the day line, STAR, small oblique arm machine robot industry, such as {Dongguan days where pneumatic} have to provide this pressure gauge
Q:How to calculate the allowable error of the pressure switch
Occupational examination questions in the operating questions are: pressure switch to allow the error = ± pressure switch set value × precision level%, of which the accuracy level is generally 1.5
Q:Fire sprinkler system pressure difference, the pressure switch in the fire control center alarm, but the hydraulic alarm did not alarm
B, when the double-contact pressure switch, the problem is simple, as long as a group of contacts wiring to the spray pump control cabinet, another group of contacts connected to the alarm host. Now the actual engineering applications, double contact pressure switch with more and more.
Q:Fire hydrant pipe network low pressure switch installed in what position
The setting of the pressure switch is highly relevant to your floor. Our GE-208F pressure switch has been widely used in multiple construction sites, good feedback. Cheng Ding electromechanical
