It has an arc extinguishing device and a certain opening and closing speed, and can pass the normal working current and the specified short-circuit circuit in the closing state. 3. It is strictly forbidden to turn on and off the circuit with load.

1. The current value of the air switch is too low, and the load power is greater than the rated power of the air switch. 2. The load joint is not firm, and the joint is not compressed. 3. If there is a short circuit in the line, check whether the electrical plug is dry. 4. The line is aging and leaking, resulting in both the live wire and the neutral line.

The so-called PNP and NPN proximity switches are for the type of DC three-wire proximity switch output transistor, and even though many proximity switch output stages use MOS transistors, they are still called the same. Differences: PNP type proximity switch: The type of proximity switch output transistor is P...

The load switch and combination electrical appliances are mainly composed of frames, isolation switches (the current limiting fuse of the combination is on the isolation switch), vacuum switch tubes, grounding switches, spring operating mechanisms, etc. The product has compact structure, small size, long life, strong closing and breaking ability, and simple operation and maintenance.

Conventional domestic travel switch LX19-001/111 in the LX19 series, LXK3-20S/T in the LXK3 series, JLXK1 series JLXK1-111/411/511 in the conventional travel switch are the most representative.

JD series warning light is Tianyi electrical appliances in the field of signal control launched high-performance products, once launched, it has won the unanimous favor of customers, products in the design, manufacturing, quality control and other aspects of the company's quality system has always been under the strict testing and supervision of the company's quality system, to ensure that each product ...

(1) The disconnector should have an obvious disconnection point, which is easy to identify whether the electrical appliance is disconnected from the power grid. (2) There should be reliable insulation between the disconnect points of the disconnector, that is, there should be enough distance between the disconnect points of the disconnector to ensure that it can work reliably under harsh climatic conditions, and ...

How to use the indicator color correctly? 1. The indicator light (also known as the signal light) is mainly used to attract the attention of the operator or instruct the operator to carry out a certain operation in the way of bright indication, and as an indication that a certain state or instruction is being executed or has been executed. 2. General ...

1. After opening, establish a reliable insulation gap to separate the equipment or line that needs to be overhauled from the power supply with an obvious disconnection point to ensure the safety of maintenance personnel and equipment. 2. According to the operation needs, change the line. 3. It can be used to divide and combine small currents in the line, ...

36V is a safe voltage, but it cannot be used as a standard for dividing high and low voltages. There are two ways to divide high and low pressure: 1. According to the rated voltage: the rated voltage is 1000V and below is called low voltage; The rated voltage of 1000V or more is called high voltage. 2. According to the voltage of the equipment to the ground...

(1) Eddy current proximity switch This type of switch is sometimes called an inductive proximity switch. It is the use of conductive objects when they are close to the proximity switch to produce eddy currents inside the object. This eddy current reacts to the proximity switch, causing the internal circuit parameters of the switch to change, so as to identify the presence or absence of ...
