Before interpreting the model meaning of the explosion-proof operating column, let us first understand the purpose of the explosion-proof operating column. It is typically used for remote or multi-location control of electrical equipment and for receiving equipment operating signals, displaying the current working status of the equipment. For example: if you live on the 10th floor and the water supply pump is on the 1st floor, installing an operating column eliminates the need to run back and forth to the 1st floor to start the pump.Simply press the button on the operation column. To know whether the pump is started, install a signal light; after the pump starts, the indicator light illuminates.。Composition of the explosion-proof operation column: It typically consists of buttons, indicator lights, selector switches, instruments, potentiometers, etc.。

Currently, there are multiple models of explosion-proof operation columns on the market, such as LBZ, BZC53, LCZ, BCZ, LNZ, BZC51, LBZ51, etc. Among them, the explosion-proof operation column model BLZ51 and the explosion-proof anti-corrosion operation column model LCZ8050 can replace the above-mentioned explosion-proof operation columns.。

Indicator lights: Color, voltage, and type of electricity include direct current (DC) and alternating current (AC); voltage includes high voltage, low voltage, and extra-low voltage.。Conventional voltages used are low voltage AC380V/220V.。 DC24V in extra-low voltage is also relatively common (in addition to the above, there are AC36V, AC48V, DC12V) [if no special requirements, AC220V is provided, 1 red and 1 green].。

Instruments: Types include voltmeters, ammeters, frequency meters, tachometers, and opening indicators. Voltage signals include DC0-10V and DC0-5V; current signals include 4-20mA and 0-20mA. Each type of instrument has multiple input signals and multiple display ranges.。The ammeter is commonly used in operation columns. Ammeter types are divided into direct input type and transformer ratio type.。Conventional transformer type has multiple single ratios. Each engineer's design selection may vary depending on the application site.。 For example, for the same 30KW motor, some choose 75/5A, some choose 100/5A, and some choose 150/5A.。

Switches: The common terminology for transfer switch functions includes three-position and two-position. Contact quantity: 1 section means two sets of contacts, 2 sections means four sets.。

Action mode: self-locking, self-resetting.。Three-position common functions: manual/stop/automatic.。Three-position with two normally open contacts is selected; two-position common functions: manual/automatic, with two-position one normally open and one normally closed selected.。Break/Make, Off/On: select two-position, two normally open contacts。

The third part, A2D2K1B1, respectively indicates: A2 means two push buttons, D2 means two indicator lights, K1 means a transfer switch (the transfer switch has selectable codes), 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 control station is the same as that of the BLZ51 control station. Both are explosion-proof control stations die-cast from aluminum alloy (steel plate and stainless steel welding are also available). LCZ8050 refers to the explosion-proof and corrosion-proof control station。
