Lighting feed circuit 2 in WE2 emergency lighting distribution box
What does APE-SZ mean in electrical construction drawings? APE-SZ stands for emergency distribution box in electrician's construction drawing.
Emergency: dealing with emergencies that need urgent treatment. Distribution box is a massive parameter in data, which generally constitutes a low-voltage forest according to electrical wiring. It is required to assemble switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal cabinet or screen to form a low-voltage distribution box. During normal operation, the circuit can be turned on or off by manual or automatic switch.
Purpose of distribution box: to distribute electric energy reasonably and facilitate the opening and closing operation of the circuit. It has a high level of safety protection and can directly display the on-off state of the circuit. Commonly used distribution boxes are made of wood and metal. Metal distribution boxes are used more because of their higher protection level.
What does the construction drawing jb 12 100 mean? If it's a drawing, look at that position. It may be a drawing number or something. Without a clear description, this question is difficult to answer.
What does ELE mean in electrical construction drawings? ELE stands for electronic leakage protection.
Leakage protector, referred to as leakage switch, also known as leakage circuit breaker, is mainly used to protect people with fatal danger from electric shock when leakage failure occurs in equipment. It has the function of overload and short circuit protection, which can be used to protect the overload and short circuit of lines or motors, and can also be used as the infrequent switching and starting of lines under normal conditions.
What does KDD·KDG mean in the electrical construction drawing? KDG- 1 Underground Remote Circuit Breaker (original KDD- 1)
Product features: it is mainly suitable for remote power-off control of low-voltage control loop of underground feed switch in coal mine, and it is explosion-proof and intrinsically safe. It can be used together with KJ90 and other monitoring system substations. It has the characteristics of small volume, light weight, reliable performance and convenient use. The main feature is that it is controlled by passive solid state circuit breaker module without external power supply; The control output is controllable; Silicon contact, suitable for low voltage AC control circuit. Main technical indicators: input control signal: passive contact output control mode: control distance from SCR contact substation to circuit breaker: ≥20km power-off control capacity: 36VAC/5A power-off control indicator light: red light indicates power-off control overall size: (200× 150× 100)mm total weight: about 4kg.
What does the letter pJQT in the construction drawing mean? You are looking at the structural professional drawings. I'm an architect and I'm not familiar with structural drawings. This kind of figure is generally compiled by the designer himself, which is related to personal habits, but everyone has a tacit understanding. Generally, it is the initial letter of a building component, such as GZ may be a constructional column or a steel column, and TJ may be a pole base. You can know what the designer represents by combining the drawings.
What does the construction drawing c 15 14a mean? This is a window on architectural drawings, with a width of 1500mm and a height of 1400 mm. I'm sure your drawings are marked with 15 14. This one is slightly different from that one, which may be in the form of a sector or an elevation, so
What do PCE and WCE in electrical construction drawings mean respectively?
PCE: strongly grounded bus
WCE: weak current grounding bus
P-power-power
Weak weak low
Current-current
E- grounding
What does 2WL 1 mean in the electrical construction drawing? WL means loop, which is usually used in design. 1 is the first cycle. The front 2 should refer to the second box (to prevent the circuit of the distribution box from repeating).
What does WL8 mean in the electrical construction drawing? I don't know what kind of drawing you mean. Generally speaking, WL means circuit, and the number is the circuit number.
