Specifications

Switchgear indicator and operator is mainly used in indoor switchgear with 0.1KV-40.5KV rated voltage.

Overview

The control and display device for switchgear is a comprehensive, multifunctional, intelligent and dynamic indicating device for various kinds of 0.1-0.45kV indoor switch cabinet. With simplified panel and well-organized layout, this switchgear accessory provides information about switch status, and it has been utilized in electric power, chemical engineering, railway, mining, metallurgy, cement and other industries.

Features

1. All the major components are of industrial grade

2. The switchgear operator adopts high-end PIC Microcontroller supplied by microchip Technology Inc.

3. Temperature data at high voltage electrical contacts are transmitted in a wireless way, so this process is safe, reliable and anti-interference

4. As for signal isolation, both discrete input and communication interface adopt optocoupler and switch while 12V relay is adopted for the output.

5. The software makes use of several leading-edge technologies, such as redundancy, fault tolerance and digital filtering, to ensure its high reliability. So, our control and display device is able to work normally under extreme conditions for a long time.

Ordering Instruction

The following information shall be provided when ordering this control and display device

1. Schematic diagram

2. Product name, model and quantity

3. Power supply:AC/DC220V or AC/DC110V

4. Wiring length for temperature and humidity sensors

5. Temperature monitoring point

6. Other special requirement

Q:Part of the rated voltage of the power equipment is marked 10.5kv, and this is similar to the label 10KV power equipment what is the difference?Consulted a lot of teachers, but it is said that this is the old and new two methods, I would like to ask what is the basis of this, it is best to have a national standard for reference: 3, rated voltage transformerRegulations, to accept the power of the primary winding, the output power of the two windings, the general, the primary winding voltage = network voltage, the voltage of the two winding due to the consideration of the loss, higher than the network voltage of 5% to 10%

Q:What are the main interference sources of the two power system: There are three kinds of electromagnetic interference in power system: electromagnetic interference between the primary equipment, the primary equipment and the secondary equipment, and between the two devices, and the electromagnetic interference between the two devices. According to the propagation path of electromagnetic disturbance, it can be divided into conduction coupling and radiation coupling. A line in the power system of switching operation, fault, lightning strikes, transient current and voltage and electromagnetic radiation line, enter the two loop through various coupling modes, these pathways are electromagnetic voltage transformer, capacitor voltage transformer, current transformer, coupling capacitor, high voltage bus and the two cable distribution between the capacitive and inductive coupling transmission way, also have a line to the surrounding space transient electromagnetic radiation energy, is two times the equipment or circuit receiving radiation coupling way.

Q:What are the characteristics of the grounding of the power system and equipment?: Security grounding - is to protect the safety of the people and set the grounding point, such as: electrical equipment shell grounding, voltage transformer grounding two times, etc..

Q:Power transformers and other equipment are what units procurement bidding, all those procedures!: Power Grid Corp on the volume of business is greater, because their main business is to invest in the construction of power grids.There are also a small number of individual units, such as large projects and large enterprises.

Q:What is the power plant: Is to do the preparation of electricity ahTransformer transformerSmall to power switch, etc.

Q:The state of power system equipment is divided into four states: (1) running state. The isolating switch and circuit breaker of the equipment are in the closing state, and the circuit is connected between the power supply and the receiving end.(2) hot standby. The circuit breaker of the equipment is disconnected, and the isolating switch is in the closing state. (3) cold standby. The circuit breakers and disconnecting switches of the equipment are in the open position.

Q:In order to obtain the qualification test of power equipment, the company needs to have a hard condition: Can not be directly applied for; there will be a variety of requirements for the application, including the number of test personnel configuration (to have a certificate, no evidence of personnel does not count), test equipment configuration (to provide invoices for the purchase of equipment, there is no light

Q:What is the installation equipment of the transformer on the power installation project: It is composed of oil immersed transformer, low voltage outlet cabinet, lightning arrester, conductor, concrete pole, insulator, hardware and iron accessories, concrete prefabricated components. Construction method:

Q:On the safety hazards of electric equipment safety: 3 where in the overhead power line protection zone new, reconstruction or expansion of the building, must go to the power supply department for the approval of the relevant procedures for the safety of power facilities construction. It is forbidden to borrow, dig fish ponds, pile up or dump harmful chemicals in the power line protection zones.4 where the demolition, the power line protection zones of overweight, lifting, drilling, piling, scaffolding and other construction work, it shall be permitted by the power supply departments, take appropriate safety measures, and can work in the power supply department under the supervision of professional staff.

Q:Recently went out to do the test, do not know the difference between the two tests: The purpose of the test is to test the performance of the equipment to prevent the occurrence of the fault, the former is the first time after the installation of the equipment to change the nature of the acceptance test, which is run during the routine. The content of the test items are different.You check the 1 power standards will know, since you do this test should have a standard hand.
