Before explaining the meaning of the explosion-proof operation column model specifications, let us first understand the purpose of the explosion-proof operation column. It is generally used for remote operation of electrical equipment at multiple locations and for receiving equipment working signals, indicating the current working status of the equipment. For example: living on the 10th floor, with the water pump on the first floor, after installing the operation column, there is no need to go back and forth to the first floor to start the centrifugal pump.Just press the button on the operating column. How do you know the water pump is turned on? Install an indicator light. After the water pump is turned on, the indicator light lights up.。Composition of the explosion-proof operating column: generally composed of buttons, indicator lights, switches, meters, resistors, etc.。

There are many models and specifications of explosion-proof operating columns on the market, such as LBZ, BZC53, LCZ, BCZ, LNZ, BZC51, LBZ51, etc. Among them, the explosion-proof operating column model BLZ51 and the explosion-proof anti-corrosion operating column model LCZ8050 can replace the above explosion-proof operating columns.。

Indicator lights: color, voltage, and power type include DC power (DC) and AC power (AC). Voltage includes high voltage, low voltage, and weak current installation.。The conventional application voltage is low voltage AC380V/220V.。 DC24V in weak current installation is also very common. (In addition to the above, there are also AC36V, AC48V, DC12V) [If there are no special requirements, AC220V with 1 red and 1 green is configured.]。

Meters: the types of meters include ammeters, current meters, frequency meters, speed meters, opening degree meters, voltage signals DC0-10V, DC0-5V; current signals 4-20mA, 0-20mA. Each type of meter has many kinds of control signals and various display ranges.。The operating column commonly uses current meters. The types of current meters are divided into direct input type and transformer ratio type.。Basic transformer type, single ratio with multiple variations. Each engineer's design may have some differences in selection due to different application occasions.。 For example, for a 30KW motor, some use 75/5A, some use 100/5A, and some choose 150/5A.。

Power switch: The toggle switch is simply referred to by its three positions and two types, with a total number of contact points of 1 section: 2 sets of contacts, 2 sections: 4 sets.。

Mounting method: Locking, self-calibration.。Three-position basic functions: Manual / Off / Automatic.。Adopts three-position two-break and two-make, two basic functions: Manual / Automatic, using two sets of one make and one break.。Open/Close, Off/On: Adopting two sets of two-break and two-make.。

The third part A2D2K1B1 respectively indicates: A2 means 2 push buttons, D2 means 2 indicator lights, K1 means a selector switch, which has optional numbering, and B1 means an instrument, including ammeter, voltmeter, etc. The ammeter must specify the current ratio.。

The model designation after the LCZ8050 series explosion-proof operating column is the same as the BLZ51 operating column. Both are explosion-proof operating columns formed by aluminum alloy casting (can also be welded from thick steel plate and stainless steel). LCZ8050 is an explosion-proof and corrosion-proof operating column.。
