What is the quota for switching power supply?
Rating switching power supplies is a common problem in electrical engineering and budgeting. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of the quota application method of switching power supplies and provide structured data for reference.
1. Basic concepts of switching power supply quota application
Switching power supply is a high-frequency power conversion device that is widely used in electronic equipment, industrial control and other fields. In the project budget, quota application refers to selecting appropriate quota sub-items to calculate the consumption of labor, materials and machinery shifts based on the specific characteristics of the project.
2. Frequently asked questions about switching power supply quota application
According to recent hot discussions on the Internet, the following are high-frequency issues regarding the application of switching power supply quotas:
| Question type | frequency of occurrence | solution |
|---|---|---|
| Fixed quota subheading selection | high frequency | Choose according to power supply and installation method |
| Material price adjustment | IF | Refer to local cost information |
| Labor cost calculation | low frequency | Execute according to quota regulations |
3. Specific methods for applying switching power supply quotas
1. Power level division:
| Power range(W) | Fixed quota sub-item number | man-day |
|---|---|---|
| 0-100 | DZ-001 | 0.5 |
| 101-500 | DZ-002 | 0.8 |
| 501-1000 | DZ-003 | 1.2 |
2. Installation method selection:
| Installation method | Fixed quota sub-item number | Adjustment factor |
|---|---|---|
| wall-mounted | AZ-001 | 1.0 |
| rack mount | AZ-002 | 1.2 |
| Embedded | AZ-003 | 1.5 |
4. Analysis of recent hot issues
1. Switching power supply quotas in new energy projects: Recently, a large number of new energy projects have been launched, and the issue of related quota application has become a hot topic. It is recommended to refer to the latest version of "New Energy Construction Project Budget Quotas".
2. Quota processing of smart switching power supplies: With the construction of smart grids, the number of smart switching power supplies with communication functions has increased, and their quotas should be increased in debugging days.
| Function type | Increase working days | Remarks |
|---|---|---|
| Basic type | 0 | No communication function |
| Intelligent | 0.5 | With communication interface |
| Advanced intelligent | 1.0 | With remote monitoring |
5. Things to note when applying quotas
1. Pay attention to regional differences: There may be differences in quota standards in different regions, and the quotas in the project location should prevail.
2. Pay attention to quota updates: Quota standards are usually updated every 3-5 years, so use the latest version.
3. Handling of special situations: For switching power supplies with special specifications, adjustments can be made with reference to similar quotas.
6. Summary
The application of switching power supply quotas requires comprehensive consideration of factors such as power, installation method, and functional characteristics. By rationally selecting the quota sub-items, the project cost can be accurately calculated. It is recommended that engineering personnel refer to relevant documents issued by the local cost management department when applying quotas to ensure the accuracy of budget preparation.
This article is based on recent hot discussions on the Internet and provides structured data and methods for applying switching power supply quotas, hoping to provide a reference for relevant practitioners. In practical applications, it needs to be handled flexibly based on the specific conditions of the project.
