浅述变压器瓦斯保护动作原因与处理方法

变压器作为一种静止的电器与其他电气设备相比,故障较少。但是,一旦变压器发生故障就会造成扬水生产中断,且需要很长的时间进行修复,从而给灌区造成严重的经济损失。因此,作为运行人员当加强对变压器运行的监视以及维护,以保证变压器能够安全运行,且将事故消灭在萌芽状态。此外,一旦发生故障必须能够正确判断事故的原因和性质并做出正确的处理防止故障扩大。本文通过介绍变压器瓦斯保护动作产生的原因,从而提出分析诊断变压器故障的基本原则和方法。

Heterogeneous treatment effects and mechanisms in information-based environmental policies: Evidence from a large-scale field experiment

Policymakers often rely on non-pecuniary, information-based programs to achieve social objectives. Using data from a water conservation information campaign implemented as a randomized controlled trial, we estimate heterogeneous household responses. Understanding such heterogeneity is important for improving the cost-effectiveness of non-pecuniary programs, extending them to other populations and probing the mechanisms through which the treatment effects arise. We find little evidence of heterogeneous responses to purely technical information or to traditional conservation messages that combine technical information and moral suasion. In contrast, norm-based messages that combine technical information, moral suasion and social comparisons exhibit strong heterogeneity: households that are wealthier, owner-occupied and use more water are more responsive. These subgroups tend to be least responsive to pecuniary incentives. We find no evidence that any subgroup increases their water use in response to the messages. By targeting the messages to subgroups known to be most responsive, program costs could be reduced by over 50% with only a 20% reduction in the treatment effect. Combining theory and data, we also shed light on the mechanisms through which the treatment effects arise, which has implications for program design and future research on the program's welfare effects.     

An economic evaluation attached to a single-centre,parallel group,unmasked, randomized controlled trial of a 3-day intensive social cognitive treatment (can do treatment) in patients with relapsing remitting multiple sclerosis and low disability

Abstract

Aims: This trial-based economic evaluation (EE) assesses from a societal perspective the cost-effectiveness of an intensive 3-day cognitive theory-based intervention (CDT), compared to care-as-usual, in patients with relapsing remitting multiple sclerosis (RRMS) and low disability (Expanded Disability Status Scale [EDDS] score < 4.0).

Materials and methods: The trial of the EE was registered in the Dutch Trial Register: Trial NL5158 (NTR5298). The incremental cost-effectiveness ratio (ICER) was expressed in cost on the Control sub-scale of the Multiple Sclerosis Self-Efficacy Scale (MSSES) and the incremental cost-utility ratio (ICUR) in the cost per Quality Adjusted Life Years (QALY) using the EQ-5D-5L. Bootstrap, sensitivity, and sub-group analyses were performed to determine the robustness of the findings.

Results: The two groups of 79 patients were similar in baseline characteristics. The base case ICER is situated in the northeast quadrant (€72 (40.74/€2,948)) due to a higher MSSES Control score and higher societal costs in the CDT group. The ICUR is situated in the northwest (inferior) quadrant due to losses in QALY and higher societal costs for the CDT group (?0.02/€2,948). Overall, bootstrap, sensitivity, and sub-group analyses confirm the base case findings. However, when the SF-6D is used as a study outcome, there is a high probability that the ICUR is situated in the northeast quadrant.

Limitations: The relative short follow-up time (6?months) and the unexpected increase in MSSES Control in the control group.

Conclusions: When using the EQ-5D-5L to calculate a QALY, CDT is not a cost-effective alternative in comparison to care as usual. However, when using self-efficacy or SF-6D as outcomes, there is a probability that CDT is cost-effective. Based on the current results, CDT for patients with RRMS clearly show its potential. However, an extended follow-up for the economic evaluation is warranted before a final decision on implementation can be made.
