One.Overview
It is a kind of fire-fighting equipment, which has the characteristics of economy, efficiency and applicability. It has become an important alternative to other fire-fighting facilities. Our company is summarizing the original products of the company and the base of similar products in China, and developing a new generation of jt-bzm fire extinguishing equipment. The new device removes the traditional electromagnetic mechanism and the operating mechanism of the heavy hammer, and USES a new mechanical and electrical control mechanism, which is accurate and reliable. It is effective to avoid the failure of the traditional product due to the corrosion of the electromagnetic mechanism pull rod track. Also effectively avoids the origin of goods movements can't continue to use, after some of the components must be replaced device itself defects, greatly reduces the product maintenance, maintenance fee, greatly extend the service life.

Three.Technical indicators
The use of environmental conditions.Ambient temperature: - 5 ℃ ~ + 40 ℃;
Storage temperature: - 25 ℃ ~ + 55 ℃;
Relative humidity: no more than 90%;
Atmospheric pressure: 80kPa~106kPa;
Working power supply
Power supply voltage: 220V,
Allowable deviation: dc -20%~+10%;
Communication - 15% ~ + 10%.
Dc power ripple coefficient: no more than 5%.
Rated frequency: 50Hz, allowable deviation: -10%~+10%.
Exchange loop
Ac voltage: 100V; Ac current: 0.25~5A;
Rated frequency: 50Hz;
When can bus in the four section, 16 lines of three-phase voltage and current for voltage deviation, frequency, and don't balance, sequence component, power (including active, reactive power, apparent), power factor, harmonic (containing rate, RMS) 2 ~ 50 times, fluctuation and flicker power quality indexes such as measurement, calculation and display.
Sampling: no less than 256 points/working frequency, three phase voltage current synchronous sampling.
The output alarm signal of the limited-harmonic index is automatically generated, and the daily harmonic limit report file is automatically generated, and the time limit, line number and measurement value of the time limit are recorded.
The measurement interval is 5~15 minutes, and the measurement data is recorded according to the set time record, and the result is saved for at least one month.
Through RS232 or RS485 serial port and field monitoring equipment communication, upload measurement data.
It can realize GPS second pulse, split pulse time function and receive GPS satellite.
It is an Ethernet interface that can communicate with background software and transmit memory records.
